|
||||
text of GPLv2 is included below. In addition to the requirements in the GPL,
|
||||
we STRONGLY ENCOURAGE you to do the following:
|
||||
|
||||
(1) Publish your entire project on a web site and drop us a note with the URL.
|
||||
Use the form at http://www.obdev.at/vusb/feedback.html for your submission.
|
||||
|
||||
(2) Adhere to minimum publication standards. Please include AT LEAST:
|
||||
- a circuit diagram in PDF, PNG or GIF format
|
||||
- full source code for the host software
|
||||
- a Readme.txt file in ASCII format which describes the purpose of the
|
||||
project and what can be found in which directories and which files
|
||||

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
||||
|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

This is the README file for USBaspLoader.
|
||||
|
||||
USBaspLoader is a USB boot loader for AVR microcontrollers. It can be used on
|
||||
all AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.
|
||||
The firmware is flashed into the upper 2 kB of the flash memory and takes
|
||||
control immediately after reset. If a certain hardware condition is met
|
||||
(this condition can be configured, e.g. a jumper), the boot loader waits for
|
||||
data on the USB interface and loads it into the remaining part of the flash
|
||||
memory. If the condition is not met, control is passed to the loaded firmware.
|
||||
|
||||
This boot loader is similar to Thomas Fischl's avrusbboot and our own
|
||||
bootloadHID, but it requires no separate command line tool to upload the data.
|
||||
USBaspLoader emulates Thomas Fischl's USBasp programmer instead. You can thus
|
||||
use AVRDUDE to upload flash memory data (and if the option is enabled) EEPROM
|
||||
data.
|
||||
|
||||
Since USBaspLoader cooperates with AVRDUDE, it can be used in conjunction with
|
||||
the Arduino software to upload flash memory data.
|
||||
|
||||
|
||||
FILES IN THE DISTRIBUTION
|
||||
=========================
|
||||
Readme.txt ........ The file you are currently reading.
|
||||
firmware .......... Source code of the controller firmware.
|
||||
firmware/usbdrv ... USB driver -- See Readme.txt in that directory for info
|
||||
License.txt ....... Public license (GPL2) for all contents of this project.
|
||||
Changelog.txt ..... Logfile documenting changes in soft-, firm- and hardware.
|
||||
|
||||
|
||||
BUILDING AND INSTALLING
|
||||
=======================
|
||||
This project can be built on Unix (Linux, FreeBSD or Mac OS X) or Windows.
|
||||
|
||||
For all platforms, you must first describe your hardware in the file
|
||||
"firmware/bootloaderconfig.h". See the documentation in the example provided
|
||||
with this distribution for details. Then edit "firmware/Makefile" to reflect
|
||||
the target device, the device's boot loader address and fuse bit values.
|
||||
|
||||
Building on Windows:
|
||||
You need WinAVR for the firmware, see http://winavr.sourceforge.net/.
|
||||
To build the firmware with WinAVR, change into the "firmware" directory,
|
||||
check whether you need to edit the "Makefile" (e.g. change device settings,
|
||||
programmer hardware, clock rate etc.) or bootloaderconfig.h and type "make"
|
||||
to compile the source code. Before you upload the code to the device with
|
||||
"make flash", you should set the fuses with "make fuse". To protect the boot
|
||||
loader from overwriting itself, set the lock bits with "make lock" after
|
||||
uploading the firmware.
|
||||
|
||||
Building on Unix (Linux, FreeBSD and Mac):
|
||||
You need the GNU toolchain and avr-libc for the firmware. See
|
||||
http://www.nongnu.org/avr-libc/user-manual/install_tools.html
|
||||
for a good description on how to install the GNU compiler toolchain and
|
||||
avr-libc on Unix. For Mac OS X, we provide a read-made package, see
|
||||
http://www.obdev.at/avrmacpack/
|
||||
|
||||
To build the firmware, change to the "firmware" directory, edit "Makefile"
|
||||
and bootloaderconfig.h as described in the Windows paragraph above and type
|
||||
"make" to compile the source code. Before you upload the code to the device
|
||||
with "make flash", you should set the fuses with "make fuse". Then protect the
|
||||
boot loader firmware with "make lock".
|
||||
|
||||
|
||||
WORKING WITH THE BOOT LOADER
|
||||
============================
|
||||
The boot loader is quite easy to use. Set the jumper (or whatever condition
|
||||
you have configured) for boot loading on the target hardware, connect it to
|
||||
the host computer and (if not bus powered) issue a Reset on the AVR.
|
||||
|
||||
You can now flash the device with AVRDUDE through a "virtual" USBasp
|
||||
programmer.
|
||||
|
||||
|
||||
USING THE USB DRIVER FOR YOUR OWN PROJECTS
|
||||
==========================================
|
||||
This project is not intended as a reference implementation. If you want to
|
||||
use AVR-USB in your own projects, please see
|
||||
* PowerSwitch for the most basic example,
|
||||
* Automator for an HID example or
|
||||
* AVR-Doper for a very complex example on how to simulate a serial
|
||||
interface (virtual COM port).
|
||||
All these projects can be downloaded from http://www.obdev.at/avrusb/
|
||||
|
||||
|
||||
ABOUT THE LICENSE
|
||||
=================
|
||||
It is our intention to make our USB driver and this demo application
|
||||
available to everyone. Moreover, we want to make a broad range of USB
|
||||
projects and ideas for USB devices available to the general public. We
|
||||
therefore want that all projects built with our USB driver are published
|
||||
under an Open Source license. Our license for the USB driver and demo code is
|
||||
the GNU General Public License Version 2 (GPL2). See the file "License.txt"
|
||||
for details.
|
||||
|
||||
If you don't want to publish your source code under the GPL2, you can simply
|
||||
pay money for AVR-USB. As an additional benefit you get USB PIDs for free,
|
||||
licensed exclusively to you. See the file "CommercialLicense.txt" in the usbdrv
|
||||
directory for details.
|
||||
|
||||

General Description:
|
||||
This file (together with some settings in Makefile) configures the boot loader
|
||||
according to the hardware.
|
||||
|
||||
This file contains (besides the hardware configuration normally found in
|
||||
usbconfig.h) two functions or macros: bootLoaderInit() and
|
||||
bootLoaderCondition(). Whether you implement them as macros or as static
|
||||
inline functions is up to you, decide based on code size and convenience.
|
||||
|
||||
bootLoaderInit() is called as one of the first actions after reset. It should
|
||||
be a minimum initialization of the hardware so that the boot loader condition
|
||||
can be read. This will usually consist of activating a pull-up resistor for an
|
||||
external jumper which selects boot loader mode.
|
||||
|
||||
bootLoaderCondition() is called immediately after initialization and in each
|
||||
main loop iteration. If it returns TRUE, the boot loader will be active. If it
|
||||
returns FALSE, the boot loader jumps to address 0 (the loaded application)
|
||||
immediately.
|
||||
|
||||
For compatibility with Thomas Fischl's avrusbboot, we also support the macro
|
||||
names BOOTLOADER_INIT and BOOTLOADER_CONDITION for this functionality. If
|
||||
these macros are defined, the boot loader usees them.

/* ------------------- Fine Control over USB Descriptors ------------------- */
|
||||
/* If you don't want to use the driver's default USB descriptors, you can
|
||||
* provide our own. These can be provided as (1) fixed length static data in
|
||||
* flash memory, (2) fixed length static data in RAM or (3) dynamically at
|
||||
* runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
|
||||
* information about this function.
|
||||
* Descriptor handling is configured through the descriptor's properties. If
|
||||
* no properties are defined or if they are 0, the default descriptor is used.
|
||||
* Possible properties are:
|
||||
* + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
|
||||
* at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
|
||||
* used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
|
||||
* you want RAM pointers.
|
||||
* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
|
||||
* in static memory is in RAM, not in flash memory.
|
||||
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
|
||||
* the driver must know the descriptor's length. The descriptor itself is
|
||||
* found at the address of a well known identifier (see below).
|
||||
* List of static descriptor names (must be declared PROGMEM if in flash):
|
||||
* char usbDescriptorDevice[];
|
||||
* char usbDescriptorConfiguration[];
|
||||
* char usbDescriptorHidReport[];
|
||||
* char usbDescriptorString0[];
|
||||
* int usbDescriptorStringVendor[];
|
||||
* int usbDescriptorStringDevice[];
|
||||
* int usbDescriptorStringSerialNumber[];
|
||||
* Other descriptors can't be provided statically, they must be provided
|
||||
* dynamically at runtime.
|
||||
*
|
||||
* Descriptor properties are or-ed or added together, e.g.:
|
||||
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
|
||||
*
|
||||
* The following descriptors are defined:
|
||||
* USB_CFG_DESCR_PROPS_DEVICE
|
||||
* USB_CFG_DESCR_PROPS_CONFIGURATION
|
||||
* USB_CFG_DESCR_PROPS_STRINGS
|
||||
* USB_CFG_DESCR_PROPS_STRING_0
|
||||
* USB_CFG_DESCR_PROPS_STRING_VENDOR
|

* USB_CFG_DESCR_PROPS_STRING_PRODUCT

* USB_CFG_DESCR_PROPS_HID
|
||||
* USB_CFG_DESCR_PROPS_HID_REPORT
|
||||
* USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
|
||||
*
|
||||
* Note about string descriptors: String descriptors are not just strings, they
|
||||
* are Unicode strings prefixed with a 2 byte header. Example:
|
||||
* int serialNumberDescriptor[] = {
|

* USB_STRING_DESCRIPTOR_HEADER(6),
|

* 'S', 'e', 'r', 'i', 'a', 'l'

This file documents changes in the firmware-only USB driver for atmel's AVR
|
||||
microcontrollers. New entries are always appended to the end of the file.
|
||||
Scroll down to the bottom to see the most recent changes.
|
||||
|
||||
2005-04-01:
|
||||
- Implemented endpoint 1 as interrupt-in endpoint.
|
||||
- Moved all configuration options to usbconfig.h which is not part of the
|
||||
driver.
|
||||
- Changed interface for usbVendorSetup().
|
||||
- Fixed compatibility with ATMega8 device.
|
||||
- Various minor optimizations.
|
||||
|
||||
2005-04-11:
|
||||
- Changed interface to application: Use usbFunctionSetup(), usbFunctionRead()
|
||||
and usbFunctionWrite() now. Added configuration options to choose which
|
||||
of these functions to compile in.
|
||||
- Assembler module delivers receive data non-inverted now.
|
||||
- Made register and bit names compatible with more AVR devices.
|
||||
|
||||
2005-05-03:
|
||||
- Allow address of usbRxBuf on any memory page as long as the buffer does
|
||||
not cross 256 byte page boundaries.
|
||||
- Better device compatibility: works with Mega88 now.
|
||||
- Code optimization in debugging module.
|
||||
- Documentation updates.
|
||||
|
||||
2006-01-02:
|
||||
- Added (free) default Vendor- and Product-IDs bought from voti.nl.
|
||||
- Added USBID-License.txt file which defines the rules for using the free
|
||||
shared VID/PID pair.
|
||||
- Added Readme.txt to the usbdrv directory which clarifies administrative
|
||||
issues.
|
||||
|
||||
2006-01-25:
|
||||
- Added "configured state" to become more standards compliant.
|
||||
- Added "HALT" state for interrupt endpoint.
|
||||
- Driver passes the "USB Command Verifier" test from usb.org now.
|
||||
- Made "serial number" a configuration option.
|
||||
- Minor optimizations, we now recommend compiler option "-Os" for best
|
||||
results.
|
||||
- Added a version number to usbdrv.h
|
||||
|
||||
2006-02-03:
|
||||
- New configuration variable USB_BUFFER_SECTION for the memory section where
|
||||
the USB rx buffer will go. This defaults to ".bss" if not defined. Since
|
||||
this buffer MUST NOT cross 256 byte pages (not even touch a page at the
|
||||
end), the user may want to pass a linker option similar to
|
||||
"-Wl,--section-start=.mybuffer=0x800060".
|
||||
- Provide structure for usbRequest_t.
|
||||
- New defines for USB constants.
|
||||
- Prepared for HID implementations.
|
||||
- Increased data size limit for interrupt transfers to 8 bytes.
|
||||
- New macro usbInterruptIsReady() to query interrupt buffer state.
|
||||
|
||||
2006-02-18:
|
||||
- Ensure that the data token which is sent as an ack to an OUT transfer is
|
||||
always zero sized. This fixes a bug where the host reports an error after
|
||||
sending an out transfer to the device, although all data arrived at the
|
||||
device.
|
||||
- Updated docs in usbdrv.h to reflect changed API in usbFunctionWrite().
|
||||
|
||||
* Release 2006-02-20
|
||||
|
||||
- Give a compiler warning when compiling with debugging turned on.
|
||||
- Added Oleg Semyonov's changes for IAR-cc compatibility.
|
||||
- Added new (optional) functions usbDeviceConnect() and usbDeviceDisconnect()
|
||||
(also thanks to Oleg!).
|
||||
- Rearranged tests in usbPoll() to save a couple of instructions in the most
|
||||
likely case that no actions are pending.
|
||||
- We need a delay between the SET ADDRESS request until the new address
|
||||
becomes active. This delay was handled in usbPoll() until now. Since the
|
||||
spec says that the delay must not exceed 2ms, previous versions required
|
||||
aggressive polling during the enumeration phase. We have now moved the
|
||||
handling of the delay into the interrupt routine.
|
||||
- We must not reply with NAK to a SETUP transaction. We can only achieve this
|
||||
by making sure that the rx buffer is empty when SETUP tokens are expected.
|
||||
We therefore don't pass zero sized data packets from the status phase of
|
||||
a transfer to usbPoll(). This change MAY cause troubles if you rely on
|
||||
receiving a less than 8 bytes long packet in usbFunctionWrite() to
|
||||
identify the end of a transfer. usbFunctionWrite() will NEVER be called
|
||||
with a zero length.
|
||||
|
||||
* Release 2006-03-14
|
||||
|
||||
- Improved IAR C support: tiny memory model, more devices
|
||||
- Added template usbconfig.h file under the name usbconfig-prototype.h
|
||||
|
||||
* Release 2006-03-26
|
||||
|
||||
- Added provision for one more interrupt-in endpoint (endpoint 3).
|
||||
- Added provision for one interrupt-out endpoint (endpoint 1).
|
||||
- Added flowcontrol macros for USB.
|
||||
- Added provision for custom configuration descriptor.
|
||||
- Allow ANY two port bits for D+ and D-.
|
||||
- Merged (optional) receive endpoint number into global usbRxToken variable.
|
||||
- Use USB_CFG_IOPORTNAME instead of USB_CFG_IOPORT. We now construct the
|
||||
variable name from the single port letter instead of computing the address
|
||||
of related ports from the output-port address.
|
||||
|
||||
* Release 2006-06-26
|
||||
|
||||
- Updated documentation in usbdrv.h and usbconfig-prototype.h to reflect the
|
||||
new features.
|
||||
- Removed "#warning" directives because IAR does not understand them. Use
|
||||
unused static variables instead to generate a warning.
|
||||
- Do not include <avr/io.h> when compiling with IAR.
|
||||
- Introduced USB_CFG_DESCR_PROPS_* in usbconfig.h to configure how each
|
||||
USB descriptor should be handled. It is now possible to provide descriptor
|
||||
data in Flash, RAM or dynamically at runtime.
|
||||
- STALL is now a status in usbTxLen* instead of a message. We can now conform
|
||||
to the spec and leave the stall status pending until it is cleared.
|
||||
- Made usbTxPacketCnt1 and usbTxPacketCnt3 public. This allows the
|
||||
application code to reset data toggling on interrupt pipes.
|
||||
|
||||
* Release 2006-07-18
|
||||
|
||||
- Added an #if !defined __ASSEMBLER__ to the warning in usbdrv.h. This fixes
|
||||
an assembler error.
|
||||
- usbDeviceDisconnect() takes pull-up resistor to high impedance now.
|
||||
|
||||
* Release 2007-02-01
|
||||
|
||||
- Merged in some code size improvements from usbtiny (thanks to Dick
|
||||
Streefland for these optimizations!)
|
||||
- Special alignment requirement for usbRxBuf not required any more. Thanks
|
||||
again to Dick Streefland for this hint!
|
||||
- Reverted to "#warning" instead of unused static variables -- new versions
|
||||
of IAR CC should handle this directive.
|
||||
- Changed Open Source license to GNU GPL v2 in order to make linking against
|
||||
other free libraries easier. We no longer require publication of the
|
||||
circuit diagrams, but we STRONGLY encourage it. If you improve the driver
|
||||
itself, PLEASE grant us a royalty free license to your changes for our
|
||||
commercial license.
|
||||
|
||||
* Release 2007-03-29
|
||||
|
||||
- New configuration option "USB_PUBLIC" in usbconfig.h.
|
||||
- Set USB version number to 1.10 instead of 1.01.
|
||||
- Code used USB_CFG_DESCR_PROPS_STRING_DEVICE and
|
||||
USB_CFG_DESCR_PROPS_STRING_PRODUCT inconsistently. Changed all occurrences
|
||||
to USB_CFG_DESCR_PROPS_STRING_PRODUCT.
|
||||
- New assembler module for 16.5 MHz RC oscillator clock with PLL in receiver
|
||||
code.
|
||||
- New assembler module for 16 MHz crystal.
|
||||
- usbdrvasm.S contains common code only, clock-specific parts have been moved
|
||||
to usbdrvasm12.S, usbdrvasm16.S and usbdrvasm165.S respectively.
|
||||
|
||||
* Release 2007-06-25
|
||||
|
||||
- 16 MHz module: Do SE0 check in stuffed bits as well.
|
||||
|
||||
* Release 2007-07-07
|
||||
|
||||
- Define hi8(x) for IAR compiler to limit result to 8 bits. This is necessary
|
||||
for negative values.
|
||||
- Added 15 MHz module contributed by V. Bosch.
|
||||
- Interrupt vector name can now be configured. This is useful if somebody
|
||||
wants to use a different hardware interrupt than INT0.
|
||||
|
||||
* Release 2007-08-07
|
||||
|
||||
- Moved handleIn3 routine in usbdrvasm16.S so that relative jump range is
|
||||
not exceeded.
|
||||
- More config options: USB_RX_USER_HOOK(), USB_INITIAL_DATATOKEN,
|
||||
USB_COUNT_SOF
|
||||
- USB_INTR_PENDING can now be a memory address, not just I/O
|
||||
|
||||
* Release 2007-09-19
|
||||
|
||||
- Split out common parts of assembler modules into separate include file
|
||||
- Made endpoint numbers configurable so that given interface definitions
|
||||
can be matched. See USB_CFG_EP3_NUMBER in usbconfig-prototype.h.
|
||||
- Store endpoint number for interrupt/bulk-out so that usbFunctionWriteOut()
|
||||
can handle any number of endpoints.
|
||||
- Define usbDeviceConnect() and usbDeviceDisconnect() even if no
|
||||
USB_CFG_PULLUP_IOPORTNAME is defined. Directly set D+ and D- to 0 in this
|
||||
case.
|
||||
|
||||
* Release 2007-12-01
|
||||
|
||||
- Optimize usbDeviceConnect() and usbDeviceDisconnect() for less code size
|
||||
when USB_CFG_PULLUP_IOPORTNAME is not defined.
|
||||
|
||||
* Release 2007-12-13
|
||||
|
||||
- Renamed all include-only assembler modules from *.S to *.inc so that
|
||||
people don't add them to their project sources.
|
||||
- Distribute leap bits in tx loop more evenly for 16 MHz module.
|
||||
- Use "macro" and "endm" instead of ".macro" and ".endm" for IAR
|
||||
- Avoid compiler warnings for constant expr range by casting some values in
|
||||
USB descriptors.
|
||||
|
||||
* Release 2008-01-21
|
||||
|
||||
- Fixed bug in 15 and 16 MHz module where the new address set with
|
||||
SET_ADDRESS was already accepted at the next NAK or ACK we send, not at
|
||||
the next data packet we send. This caused problems when the host polled
|
||||
too fast. Thanks to Alexander Neumann for his help and patience debugging
|
||||
this issue!
|
||||
|
||||
* Release 2008-02-05
|
||||
|
||||
- Fixed bug in 16.5 MHz module where a register was used in the interrupt
|
||||
handler before it was pushed. This bug was introduced with version
|
||||
2007-09-19 when common parts were moved to a separate file.
|
||||
- Optimized CRC routine (thanks to Reimar Doeffinger).
|
||||
|
||||
* Release 2008-02-16
|
||||
|
||||
- Removed outdated IAR compatibility stuff (code sections).
|
||||
- Added hook macros for USB_RESET_HOOK() and USB_SET_ADDRESS_HOOK().
|
||||
- Added optional routine usbMeasureFrameLength() for calibration of the
|
||||
internal RC oscillator.
|
||||
|
||||
* Release 2008-02-28
|
||||
|
||||
- USB_INITIAL_DATATOKEN defaults to USBPID_DATA1 now, which means that we
|
||||
start with sending USBPID_DATA0.
|
||||
- Changed defaults in usbconfig-prototype.h
|
||||
- Added free USB VID/PID pair for MIDI class devices
|
||||
- Restructured AVR-USB as separate package, not part of PowerSwitch any more.
|
||||
|
||||
* Release 2008-04-18
|
||||
|
||||
- Restructured usbdrv.c so that it is easier to read and understand.
|
||||
- Better code optimization with gcc 4.
|
||||
- If a second interrupt in endpoint is enabled, also add it to config
|
||||
descriptor.
|
||||
- Added config option for long transfers (above 254 bytes), see
|
||||
USB_CFG_LONG_TRANSFERS in usbconfig.h.
|
||||
- Added 20 MHz module contributed by Jeroen Benschop.
|
||||
|
||||
* Release 2008-05-13
|
||||
|
||||
- Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length
|
||||
was not incremented, pointer to length was incremented instead.
|
||||
- Added code to command line tool(s) which claims an interface. This code
|
||||
is disabled by default, but may be necessary on newer Linux kernels.
|
||||
- Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING".
|
||||
- New header "usbportability.h" prepares ports to other development
|
||||
environments.
|
||||
- Long transfers (above 254 bytes) did not work when usbFunctionRead() was
|
||||
used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!]
|
||||
- In hiddata.c (example code for sending/receiving data over HID), use
|
||||
USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so
|
||||
that we need not claim the interface.
|
||||
- in usbPoll() loop 20 times polling for RESET state instead of 10 times.
|
||||
This accounts for the higher clock rates we now support.
|
||||
- Added a module for 12.8 MHz RC oscillator with PLL in receiver loop.
|
||||
- Added hook to SOF code so that oscillator can be tuned to USB frame clock.
|
||||
- Added timeout to waitForJ loop. Helps preventing unexpected hangs.
|
||||
- Added example code for oscillator tuning to libs-device (thanks to
|
||||
Henrik Haftmann for the idea to this routine).
|
||||
- Implemented option USB_CFG_SUPPRESS_INTR_CODE.
|
||||
|
||||
* Release 2008-10-22
|
||||
|
||||
- Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and
|
||||
similar, not offset of 0x20 needs to be added.
|
||||
- Allow distribution under GPLv3 for those who have to link against other
|
||||
code distributed under GPLv3.
|
||||
|
||||
* Release 2008-11-26
|
||||
|
||||
- Removed libusb-win32 dependency for hid-data example in Makefile.windows.
|
||||
It was never required and confused many people.
|
||||
- Added extern uchar usbRxToken to usbdrv.h.
|
||||
- Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser.
|
||||
|
||||
* Release 2009-03-23
|
||||
|
||||
- Hid-mouse example used settings from hid-data example, fixed that.
|
||||
- Renamed project to V-USB due to a trademark issue with Atmel(r).
|
||||
- Changed CommercialLicense.txt and USBID-License.txt to make the
|
||||
background of USB ID registration clearer.
|
||||
|
||||
* Release 2009-04-15
|
||||
|
||||
- Changed CommercialLicense.txt to reflect the new range of PIDs from
|
||||
Jason Kotzin.
|
||||
- Removed USBID-License.txt in favor of USB-IDs-for-free.txt and
|
||||
USB-ID-FAQ.txt
|
||||
- Fixed a bug in the 12.8 MHz module: End Of Packet decection was made in
|
||||
the center between bit 0 and 1 of each byte. This is where the data lines
|
||||
are expected to change and the sampled data may therefore be nonsense.
|
||||
We therefore check EOP ONLY if bits 0 AND 1 have both been read as 0 on D-.
|
||||
- Fixed a bitstuffing problem in the 16 MHz module: If bit 6 was stuffed,
|
||||
the unstuffing code in the receiver routine was 1 cycle too long. If
|
||||
multiple bytes had the unstuffing in bit 6, the error summed up until the
|
||||
receiver was out of sync.
|
||||
- Included option for faster CRC routine.
|
||||
Thanks to Slawomir Fras (BoskiDialer) for this code!
|
||||
- Updated bits in Configuration Descriptor's bmAttributes according to
|
||||
USB 1.1 (in particular bit 7, it is a must-be-set bit now).
|
||||
|
||||
* Release 2009-08-22
|
||||
|
||||
- Moved first DBG1() after odDebugInit() in all examples.
|
||||
- Use vector INT0_vect instead of SIG_INTERRUPT0 if defined. This makes
|
||||
V-USB compatible with the new "p" suffix devices (e.g. ATMega328p).
|
||||
- USB_CFG_CLOCK_KHZ setting is now required in usbconfig.h (no default any
|
||||
more).
|
||||
- New option USB_CFG_DRIVER_FLASH_PAGE allows boot loaders on devices with
|
||||
more than 64 kB flash.
|
||||
- Built-in configuration descriptor allows custom definition for second
|
||||
endpoint now.

V-USB Driver Software License Agreement
|
||||
Version 2009-08-03
|
||||
|
||||
THIS LICENSE AGREEMENT GRANTS YOU CERTAIN RIGHTS IN A SOFTWARE. YOU CAN
|
||||
ENTER INTO THIS AGREEMENT AND ACQUIRE THE RIGHTS OUTLINED BELOW BY PAYING
|
||||
THE AMOUNT ACCORDING TO SECTION 4 ("PAYMENT") TO OBJECTIVE DEVELOPMENT.
|
||||
|
||||
|
||||
1 DEFINITIONS
|
||||
|
||||
1.1 "OBJECTIVE DEVELOPMENT" shall mean OBJECTIVE DEVELOPMENT Software GmbH,
|
||||
Grosse Schiffgasse 1A/7, 1020 Wien, AUSTRIA.
|
||||
|
||||
1.2 "You" shall mean the Licensee.
|
||||
|
||||
1.3 "V-USB" shall mean all files included in the package distributed under
|
||||
the name "vusb" by OBJECTIVE DEVELOPMENT (http://www.obdev.at/vusb/)
|
||||
unless otherwise noted. This includes the firmware-only USB device
|
||||
implementation for Atmel AVR microcontrollers, some simple device examples
|
||||
and host side software examples and libraries.
|
||||
|
||||
|
||||
2 LICENSE GRANTS
|
||||
|
||||
2.1 Source Code. OBJECTIVE DEVELOPMENT shall furnish you with the source
|
||||
code of V-USB.
|
||||
|
||||
2.2 Distribution and Use. OBJECTIVE DEVELOPMENT grants you the
|
||||
non-exclusive right to use, copy and distribute V-USB with your hardware
|
||||
product(s), restricted by the limitations in section 3 below.
|
||||
|
||||
2.3 Modifications. OBJECTIVE DEVELOPMENT grants you the right to modify
|
||||
the source code and your copy of V-USB according to your needs.
|
||||
|
||||
2.4 USB IDs. OBJECTIVE DEVELOPMENT furnishes you with one or two USB
|
||||
Product ID(s), sent to you in e-mail. These Product IDs are reserved
|
||||
exclusively for you. OBJECTIVE DEVELOPMENT has obtained USB Product ID
|
||||
ranges under the Vendor ID 5824 from Wouter van Ooijen (Van Ooijen
|
||||
Technische Informatica, www.voti.nl) and under the Vendor ID 8352 from
|
||||
Jason Kotzin (Clay Logic, www.claylogic.com). Both owners of the Vendor IDs
|
||||
have obtained these IDs from the USB Implementers Forum, Inc.
|
||||
(www.usb.org). OBJECTIVE DEVELOPMENT disclaims all liability which might
|
||||
arise from the assignment of USB IDs.
|
||||
|
||||
2.5 USB Certification. Although not part of this agreement, we want to make
|
||||
it clear that you cannot become USB certified when you use V-USB or a USB
|
||||
Product ID assigned by OBJECTIVE DEVELOPMENT. AVR microcontrollers don't
|
||||
meet the electrical specifications required by the USB specification and
|
||||
the USB Implementers Forum certifies only members who bought a Vendor ID of
|
||||
their own.
|
||||
|
||||
|
||||
3 LICENSE RESTRICTIONS
|
||||
|
||||
3.1 Number of Units. Only one of the following three definitions is
|
||||
applicable. Which one is determined by the amount you pay to OBJECTIVE
|
||||
DEVELOPMENT, see section 4 ("Payment") below.
|
||||
|
||||
Hobby License: You may use V-USB according to section 2 above in no more
|
||||
than 5 hardware units. These units must not be sold for profit.
|
||||
|
||||
Entry Level License: You may use V-USB according to section 2 above in no
|
||||
more than 150 hardware units.
|
||||
|
||||
Professional License: You may use V-USB according to section 2 above in
|
||||
any number of hardware units, except for large scale production ("unlimited
|
||||
fair use"). Quantities below 10,000 units are not considered large scale
|
||||
production. If your reach quantities which are obviously large scale
|
||||
production, you must pay a license fee of 0.10 EUR per unit for all units
|
||||
above 10,000.
|
||||
|
||||
3.2 Rental. You may not rent, lease, or lend V-USB or otherwise encumber
|
||||
any copy of V-USB, or any of the rights granted herein.
|
||||
|
||||
3.3 Transfer. You may not transfer your rights under this Agreement to
|
||||
another party without OBJECTIVE DEVELOPMENT's prior written consent. If
|
||||
such consent is obtained, you may permanently transfer this License to
|
||||
another party. The recipient of such transfer must agree to all terms and
|
||||
conditions of this Agreement.
|
||||
|
||||
3.4 Reservation of Rights. OBJECTIVE DEVELOPMENT retains all rights not
|
||||
expressly granted.
|
||||
|
||||
3.5 Non-Exclusive Rights. Your license rights under this Agreement are
|
||||
non-exclusive.
|
||||
|
||||
3.6 Third Party Rights. This Agreement cannot grant you rights controlled
|
||||
by third parties. In particular, you are not allowed to use the USB logo or
|
||||
other trademarks owned by the USB Implementers Forum, Inc. without their
|
||||
consent. Since such consent depends on USB certification, it should be
|
||||
noted that V-USB will not pass certification because it does not
|
||||
implement checksum verification and the microcontroller ports do not meet
|
||||
the electrical specifications.
|
||||
|
||||
|
||||
4 PAYMENT
|
||||
|
||||
The payment amount depends on the variation of this agreement (according to
|
||||
section 3.1) into which you want to enter. Concrete prices are listed on
|
||||
OBJECTIVE DEVELOPMENT's web site, usually at
|
||||
http://www.obdev.at/vusb/license.html. You agree to pay the amount listed
|
||||
there to OBJECTIVE DEVELOPMENT or OBJECTIVE DEVELOPMENT's payment processor
|
||||
or reseller.
|
||||
|
||||
|
||||
5 COPYRIGHT AND OWNERSHIP
|
||||
|
||||
V-USB is protected by copyright laws and international copyright
|
||||
treaties, as well as other intellectual property laws and treaties. V-USB
|
||||
is licensed, not sold.
|
||||
|
||||
|
||||
6 TERM AND TERMINATION
|
||||
|
||||
6.1 Term. This Agreement shall continue indefinitely. However, OBJECTIVE
|
||||
DEVELOPMENT may terminate this Agreement and revoke the granted license and
|
||||
USB-IDs if you fail to comply with any of its terms and conditions.
|
||||
|
||||
6.2 Survival of Terms. All provisions regarding secrecy, confidentiality
|
||||
and limitation of liability shall survive termination of this agreement.
|
||||
|
||||
|
||||
7 DISCLAIMER OF WARRANTY AND LIABILITY
|
||||
|
||||
LIMITED WARRANTY. V-USB IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY
|
||||
KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OBJECTIVE
|
||||
DEVELOPMENT AND ITS SUPPLIERS HEREBY DISCLAIM ALL WARRANTIES, EITHER
|
||||
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
|
||||
OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND
|
||||
NON-INFRINGEMENT, WITH REGARD TO V-USB, AND THE PROVISION OF OR FAILURE
|
||||
TO PROVIDE SUPPORT SERVICES. THIS LIMITED WARRANTY GIVES YOU SPECIFIC LEGAL
|
||||
RIGHTS. YOU MAY HAVE OTHERS, WHICH VARY FROM STATE/JURISDICTION TO
|
||||
STATE/JURISDICTION.
|
||||
|
||||
LIMITATION OF LIABILITY. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW,
|
||||
IN NO EVENT SHALL OBJECTIVE DEVELOPMENT OR ITS SUPPLIERS BE LIABLE FOR ANY
|
||||
SPECIAL, INCIDENTAL, INDIRECT, OR CONSEQUENTIAL DAMAGES WHATSOEVER
|
||||
(INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF BUSINESS PROFITS,
|
||||
BUSINESS INTERRUPTION, LOSS OF BUSINESS INFORMATION, OR ANY OTHER PECUNIARY
|
||||
LOSS) ARISING OUT OF THE USE OF OR INABILITY TO USE V-USB OR THE
|
||||
PROVISION OF OR FAILURE TO PROVIDE SUPPORT SERVICES, EVEN IF OBJECTIVE
|
||||
DEVELOPMENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN ANY
|
||||
CASE, OBJECTIVE DEVELOPMENT'S ENTIRE LIABILITY UNDER ANY PROVISION OF THIS
|
||||
AGREEMENT SHALL BE LIMITED TO THE AMOUNT ACTUALLY PAID BY YOU FOR V-USB.
|
||||
|
||||
|
||||
8 MISCELLANEOUS TERMS
|
||||
|
||||
8.1 Marketing. OBJECTIVE DEVELOPMENT has the right to mention for marketing
|
||||

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of

If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>

CPU CORE CLOCK FREQUENCY
|
||||
========================
|
||||
We supply assembler modules for clock frequencies of 12 MHz, 12.8 MHz, 15 MHz,
|
||||
16 MHz, 16.5 MHz 18 MHz and 20 MHz. Other clock rates are not supported. The
|
||||
actual clock rate must be configured in usbconfig.h.
|
||||
|
||||
12 MHz Clock
|
||||
This is the traditional clock rate of V-USB because it's the lowest clock
|
||||
rate where the timing constraints of the USB spec can be met.
|
||||
|
||||
15 MHz Clock
|
||||
Similar to 12 MHz, but some NOPs inserted. On the other hand, the higher clock
|
||||
rate allows for some loops which make the resulting code size somewhat smaller
|
||||
than the 12 MHz version.
|
||||
|
||||
16 MHz Clock
|
||||
This clock rate has been added for users of the Arduino board and other
|
||||
ready-made boards which come with a fixed 16 MHz crystal. It's also an option
|
||||
if you need the slightly higher clock rate for performance reasons. Since
|
||||
16 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code
|
||||
is somewhat tricky and has to insert a leap cycle every third byte.
|
||||
|
||||
12.8 MHz and 16.5 MHz Clock
|
||||
The assembler modules for these clock rates differ from the other modules
|
||||
because they have been built for an RC oscillator with only 1% precision. The
|
||||
receiver code inserts leap cycles to compensate for clock deviations. 1% is
|
||||
also the precision which can be achieved by calibrating the internal RC
|
||||
oscillator of the AVR. Please note that only AVRs with internal 64 MHz PLL
|
||||
oscillator can reach 16.5 MHz with the RC oscillator. This includes the very
|
||||
popular ATTiny25, ATTiny45, ATTiny85 series as well as the ATTiny26. Almost
|
||||
all AVRs can reach 12.8 MHz, although this is outside the specified range.
|
||||
|
||||
See the EasyLogger example at http://www.obdev.at/vusb/easylogger.html for
|
||||
code which calibrates the RC oscillator based on the USB frame clock.
|
||||
|
||||
18 MHz Clock
|
||||
This module is closer to the USB specification because it performs an on the
|
||||
fly CRC check for incoming packets. Packets with invalid checksum are
|
||||
discarded as required by the spec. If you also implement checks for data
|
||||
PID toggling on application level (see option USB_CFG_CHECK_DATA_TOGGLING
|
||||
in usbconfig.h for more info), this ensures data integrity. Due to the CRC
|
||||
tables and alignment requirements, this code is bigger than modules for other
|
||||
clock rates. To activate this module, you must define USB_CFG_CHECK_CRC to 1
|
||||
and USB_CFG_CLOCK_KHZ to 18000 in usbconfig.h.
|
||||
|
||||
20 MHz Clock
|
||||
This module is for people who won't do it with less than the maximum. Since
|
||||
20 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code
|
||||
uses similar tricks as the 16 MHz module to insert leap cycles.
|
||||
|
||||
|
||||
USB IDENTIFIERS
|
||||
===============
|
||||
Every USB device needs a vendor- and a product-identifier (VID and PID). VIDs
|
||||
are obtained from usb.org for a price of 1,500 USD. Once you have a VID, you
|
||||
can assign PIDs at will.
|
||||
|
||||
Since an entry level cost of 1,500 USD is too high for most small companies
|
||||
and hobbyists, we provide some VID/PID pairs for free. See the file
|
||||
USB-IDs-for-free.txt for details.
|
||||
|
||||
Objective Development also has some license offerings which include product
|
||||
IDs. See http://www.obdev.at/vusb/ for details.
|
||||
|
||||
|
||||
DEVELOPMENT SYSTEM
|
||||
==================
|
||||
This driver has been developed and optimized for the GNU compiler version 3
|
||||
and 4. We recommend that you use the GNU compiler suite because it is freely
|
||||
available. V-USB has also been ported to the IAR compiler and assembler. It
|
||||
has been tested with IAR 4.10B/W32 and 4.12A/W32 on an ATmega8 with the
|
||||
"small" and "tiny" memory model. Not every release is tested with IAR CC and
|
||||
the driver may therefore fail to compile with IAR. Please note that gcc is
|
||||
more efficient for usbdrv.c because this module has been deliberately
|
||||
optimized for gcc.
|
||||
|
||||
Gcc version 3 produces smaller code than version 4 due to new optimizing
|
||||
capabilities which don't always improve things on 8 bit CPUs. The code size
|
||||
generated by gcc 4 can be reduced with the compiler options
|
||||
-fno-move-loop-invariants, -fno-tree-scev-cprop and
|
||||
-fno-inline-small-functions in addition to -Os. On devices with more than
|
||||
8k of flash memory, we also recommend the linker option --relax (written as
|
||||
-Wl,--relax for gcc) to convert absolute calls into relative where possible.
|
||||
|
||||
For more information about optimizing options see:
|
||||
|
||||
http://www.tty1.net/blog/2008-04-29-avr-gcc-optimisations_en.html
|
||||
|
||||
These optimizations are good for gcc 4.x. Version 3.x of gcc does not support
|
||||
most of these options and produces good code anyway.

||||

Version 2009-08-22
|
||||
|
||||
==========================
|
||||
WHY DO WE NEED THESE IDs?
|
||||
==========================
|
||||
|
||||
USB is more than a low level protocol for data transport. It also defines a
|
||||
common set of requests which must be understood by all devices. And as part
|
||||
of these common requests, the specification defines data structures, the
|
||||
USB Descriptors, which are used to describe the properties of the device.
|
||||
|
||||
From the perspective of an operating system, it is therefore possible to find
|
||||
out basic properties of a device (such as e.g. the manufacturer and the name
|
||||
of the device) without a device-specific driver. This is essential because
|
||||
the operating system can choose a driver to load based on this information
|
||||
(Plug-And-Play).
|
||||
|
||||
Among the most important properties in the Device Descriptor are the USB
|
||||
Vendor- and Product-ID. Both are 16 bit integers. The most simple form of
|
||||
driver matching is based on these IDs. The driver announces the Vendor- and
|
||||
Product-IDs of the devices it can handle and the operating system loads the
|
||||
appropriate driver when the device is connected.
|
||||
|
||||
It is obvious that this technique only works if the pair Vendor- plus
|
||||
Product-ID is unique: Only devices which require the same driver can have the
|
||||
same pair of IDs.
|
||||
|
||||
|
||||
=====================================================
|
||||
HOW DOES THE USB STANDARD ENSURE THAT IDs ARE UNIQUE?
|
||||
=====================================================
|
||||
|
||||
Since it is so important that USB IDs are unique, the USB Implementers Forum,
|
||||
Inc. (usb.org) needs a way to enforce this legally. It is not forbidden by
|
||||
law to build a device and assign it any random numbers as IDs. Usb.org
|
||||
therefore needs an agreement to regulate the use of USB IDs. The agreement
|
||||
binds only parties who agreed to it, of course. Everybody else is free to use
|
||||
any numbers for their IDs.
|
||||
|
||||
So how can usb.org ensure that every manufacturer of USB devices enters into
|
||||
an agreement with them? They do it via trademark licensing. Usb.org has
|
||||
registered the trademark "USB", all associated logos and related terms. If
|
||||
you want to put an USB logo on your product or claim that it is USB
|
||||
compliant, you must license these trademarks from usb.org. And this is where
|
||||
you enter into an agreement. See the "USB-IF Trademark License Agreement and
|
||||
Usage Guidelines for the USB-IF Logo" at
|
||||
http://www.usb.org/developers/logo_license/.
|
||||
|
||||
Licensing the USB trademarks requires that you buy a USB Vendor-ID from
|
||||
usb.org (one-time fee of ca. 2,000 USD), that you become a member of usb.org
|
||||
(yearly fee of ca. 4,000 USD) and that you meet all the technical
|
||||
specifications from the USB spec.
|
||||
|
||||
This means that most hobbyists and small companies will never be able to
|
||||
become USB compliant, just because membership is so expensive. And you can't
|
||||
be compliant with a driver based on V-USB anyway, because the AVR's port pins
|
||||
don't meet the electrical specifications for USB. So, in principle, all
|
||||
hobbyists and small companies are free to choose any random numbers for their
|
||||
IDs. They have nothing to lose...
|
||||
|
||||
There is one exception worth noting, though: If you use a sub-component which
|
||||
implements USB, the vendor of the sub-components may guarantee USB
|
||||
compliance. This might apply to some or all of FTDI's solutions.
|
||||
|
||||
|
||||
=======================================================================
|
||||
WHY SHOULD YOU OBTAIN USB IDs EVEN IF YOU DON'T LICENSE USB TRADEMARKS?
|
||||
=======================================================================
|
||||
|
||||
You have learned in the previous section that you are free to choose any
|
||||
numbers for your IDs anyway. So why not do exactly this? There is still the
|
||||
technical issue. If you choose IDs which are already in use by somebody else,
|
||||
operating systems will load the wrong drivers and your device won't work.
|
||||
Even if you choose IDs which are not currently in use, they may be in use in
|
||||
the next version of the operating system or even after an automatic update.
|
||||
|
||||
So what you need is a pair of Vendor- and Product-IDs for which you have the
|
||||
guarantee that no USB compliant product uses them. This implies that no
|
||||
operating system will ever ship with drivers responsible for these IDs.
|
||||
|
||||
|
||||
==============================================
|
||||
HOW DOES OBJECTIVE DEVELOPMENT HANDLE USB IDs?
|
||||
==============================================
|
||||
|
||||
Objective Development gives away pairs of USB-IDs with their V-USB licenses.
|
||||
In order to ensure that these IDs are unique, Objective Development has an
|
||||
agreement with the company/person who has bought the USB Vendor-ID from
|
||||
usb.org. This agreement ensures that a range of USB Product-IDs is reserved
|
||||
for assignment by Objective Development and that the owner of the Vendor-ID
|
||||
won't give it to anybody else.
|
||||
|
||||
This means that you have to trust three parties to ensure uniqueness of
|
||||
your IDs:
|
||||
|
||||
- Objective Development, that they don't give the same PID to more than
|
||||
one person.
|
||||
- The owner of the Vendor-ID that they don't assign PIDs from the range
|
||||
assigned to Objective Development to anybody else.
|
||||
- Usb.org that they don't assign the same Vendor-ID a second time.
|
||||
|
||||
|
||||
==================================
|
||||
WHO IS THE OWNER OF THE VENDOR-ID?
|
||||
==================================
|
||||
|
||||
Objective Development has obtained ranges of USB Product-IDs under two
|
||||
Vendor-IDs: Under Vendor-ID 5824 from Wouter van Ooijen (Van Ooijen
|
||||
Technische Informatica, www.voti.nl) and under Vendor-ID 8352 from Jason
|
||||
Kotzin (Clay Logic, www.claylogic.com). Both VID owners have received their
|
||||
Vendor-ID directly from usb.org.
|
||||
|
||||
|
||||
=========================================================================
|
||||
CAN I USE USB-IDs FROM OBJECTIVE DEVELOPMENT WITH OTHER DRIVERS/HARDWARE?
|
||||
=========================================================================
|
||||
|
||||
The short answer is: Yes. All you get is a guarantee that the IDs are never
|
||||
assigned to anybody else. What more do you need?
|
||||
|
||||
|
||||
============================
|
||||
WHAT ABOUT SHARED ID PAIRS?
|
||||
============================
|
||||
|
||||
Objective Development has reserved some PID/VID pairs for shared use. You
|
||||
have no guarantee of uniqueness for them, except that no USB compliant device
|
||||
uses them. In order to avoid technical problems, we must ensure that all
|
||||
devices with the same pair of IDs use the same driver on kernel level. For
|
||||
details, see the file USB-IDs-for-free.txt.
|
||||
|
||||
|
||||
======================================================
|
||||
I HAVE HEARD THAT SUB-LICENSING OF USB-IDs IS ILLEGAL?
|
||||
======================================================
|
||||
|
||||
A 16 bit integer number cannot be protected by copyright laws. It is not
|
||||
sufficiently complex. And since none of the parties involved entered into the
|
||||
USB-IF Trademark License Agreement, we are not bound by this agreement. So
|
||||
there is no reason why it should be illegal to sub-license USB-IDs.
|
||||
|
||||
|
||||
=============================================
|
||||
WHO IS LIABLE IF THERE ARE INCOMPATIBILITIES?
|
||||
=============================================
|
||||
|
||||
Objective Development disclaims all liabilities which might arise from the
|
||||
assignment of IDs. If you guarantee product features to your customers
|
||||
without proper disclaimer, YOU are liable for that.

FREE USB-IDs FOR SHARED USE
|
||||
===========================
|
||||
|
||||
Objective Development has reserved a set of USB Product-IDs for use according
|
||||
to the guidelines outlined below. For more information about the concept of
|
||||
USB IDs please see the file USB-ID-FAQ.txt. Objective Development guarantees
|
||||
that the IDs listed below are not used by any USB compliant devices.
|
||||
|
||||
|
||||
====================
|
||||
MECHANISM OF SHARING
|
||||
====================
|
||||
|
||||
From a technical point of view, two different devices can share the same USB
|
||||
Vendor- and Product-ID if they require the same driver on operating system
|
||||
level. We make use of this fact by assigning separate IDs for various device
|
||||
classes. On application layer, devices must be distinguished by their textual
|
||||
name or serial number. We offer separate sets of IDs for discrimination by
|
||||
textual name and for serial number.
|
||||
|
||||
Examples for shared use of USB IDs are included with V-USB in the "examples"
|
||||
subdirectory.
|
||||
|
||||
|
||||
======================================
|
||||
IDs FOR DISCRIMINATION BY TEXTUAL NAME
|
||||
======================================
|
||||
|
||||
If you use one of the IDs listed below, your device and host-side software
|
||||
must conform to these rules:
|
||||
|
||||
(1) The USB device MUST provide a textual representation of the manufacturer
|
||||
and product identification. The manufacturer identification MUST be available
|
||||
at least in USB language 0x0409 (English/US).
|
||||
|
||||
(2) The textual manufacturer identification MUST contain either an Internet
|
||||
domain name (e.g. "mycompany.com") registered and owned by you, or an e-mail
|
||||
address under your control (e.g. "myname@gmx.net"). You can embed the domain
|
||||
name or e-mail address in any string you like, e.g. "Objective Development
|
||||
http://www.obdev.at/vusb/".
|
||||
|
||||
(3) You are responsible for retaining ownership of the domain or e-mail
|
||||
address for as long as any of your products are in use.
|
||||
|
||||
(4) You may choose any string for the textual product identification, as long
|
||||
as this string is unique within the scope of your textual manufacturer
|
||||
identification.
|
||||
|
||||
(5) Application side device look-up MUST be based on the textual manufacturer
|
||||
and product identification in addition to VID/PID matching. The driver
|
||||
matching MUST be a comparison of the entire strings, NOT a sub-string match.
|
||||
|
||||
(6) For devices which implement a particular USB device class (e.g. HID), the
|
||||
operating system's default class driver MUST be used. If an operating system
|
||||
driver for Vendor Class devices is needed, this driver must be libusb or
|
||||
libusb-win32 (see http://libusb.org/ and
|
||||
http://libusb-win32.sourceforge.net/).
|
||||
|
||||
Table if IDs for discrimination by textual name:
|
||||
|
||||
PID dec (hex) | VID dec (hex) | Description of use
|
||||
==============+===============+============================================
|
||||
1500 (0x05dc) | 5824 (0x16c0) | For Vendor Class devices with libusb
|
||||
--------------+---------------+--------------------------------------------
|
||||
1503 (0x05df) | 5824 (0x16c0) | For generic HID class devices (which are
|
||||
| | NOT mice, keyboards or joysticks)
|
||||
--------------+---------------+--------------------------------------------
|
||||
1505 (0x05e1) | 5824 (0x16c0) | For CDC-ACM class devices (modems)
|
||||
--------------+---------------+--------------------------------------------
|
||||
1508 (0x05e4) | 5824 (0x16c0) | For MIDI class devices
|
||||
--------------+---------------+--------------------------------------------
|
||||
|
||||
Note that Windows caches the textual product- and vendor-description for
|
||||
mice, keyboards and joysticks. Name-bsed discrimination is therefore not
|
||||
recommended for these device classes.
|
||||
|
||||
|
||||
=======================================
|
||||
IDs FOR DISCRIMINATION BY SERIAL NUMBER
|
||||
=======================================
|
||||
|
||||
If you use one of the IDs listed below, your device and host-side software
|
||||
must conform to these rules:
|
||||
|
||||
(1) The USB device MUST provide a textual representation of the serial
|
||||
number. The serial number string MUST be available at least in USB language
|
||||
0x0409 (English/US).
|
||||
|
||||
(2) The serial number MUST start with either an Internet domain name (e.g.
|
||||
"mycompany.com") registered and owned by you, or an e-mail address under your
|
||||
control (e.g. "myname@gmx.net"), both terminated with a colon (":") character.
|
||||
You MAY append any string you like for further discrimination of your devices.
|
||||
|
||||
(3) You are responsible for retaining ownership of the domain or e-mail
|
||||
address for as long as any of your products are in use.
|
||||
|
||||
(5) Application side device look-up MUST be based on the serial number string
|
||||
in addition to VID/PID matching. The matching must start at the first
|
||||
character of the serial number string and include the colon character
|
||||
terminating your domain or e-mail address. It MAY stop anywhere after that.
|
||||
|
||||
(6) For devices which implement a particular USB device class (e.g. HID), the
|
||||
operating system's default class driver MUST be used. If an operating system
|
||||
driver for Vendor Class devices is needed, this driver must be libusb or
|
||||
libusb-win32 (see http://libusb.org/ and
|
||||
http://libusb-win32.sourceforge.net/).

This file is an example configuration (with inline documentation) for the USB

|
||||
also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
|
||||
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
|
||||
other hardware interrupt, as long as it is the highest level interrupt, see
|
||||
section at the end of this file).
|
||||
+ To create your own usbconfig.h file, copy this file to your project's
|
||||
+ firmware source directory) and rename it to "usbconfig.h".
|

* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
|
||||
* in static memory is in RAM, not in flash memory.
|
||||
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
|
||||
* the driver must know the descriptor's length. The descriptor itself is
|
||||
* found at the address of a well known identifier (see below).
|
||||
* List of static descriptor names (must be declared PROGMEM if in flash):
|
||||
* char usbDescriptorDevice[];
|
||||
* char usbDescriptorConfiguration[];
|
||||
* char usbDescriptorHidReport[];
|
||||
* char usbDescriptorString0[];
|
||||
* int usbDescriptorStringVendor[];
|
||||
* int usbDescriptorStringDevice[];
|
||||
* int usbDescriptorStringSerialNumber[];
|
||||
* Other descriptors can't be provided statically, they must be provided
|
||||
* dynamically at runtime.
|
||||
*
|
||||
* Descriptor properties are or-ed or added together, e.g.:
|
||||
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
|
||||
*
|
||||
* The following descriptors are defined:
|
||||
* USB_CFG_DESCR_PROPS_DEVICE
|
||||
* USB_CFG_DESCR_PROPS_CONFIGURATION
|
||||
* USB_CFG_DESCR_PROPS_STRINGS
|
||||
* USB_CFG_DESCR_PROPS_STRING_0
|
||||
* USB_CFG_DESCR_PROPS_STRING_VENDOR
|
||||
* USB_CFG_DESCR_PROPS_STRING_PRODUCT
|
||||
* USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
|
||||
* USB_CFG_DESCR_PROPS_HID
|
||||
* USB_CFG_DESCR_PROPS_HID_REPORT
|
||||
* USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
|
||||
*
|
||||
* Note about string descriptors: String descriptors are not just strings, they
|
||||
* are Unicode strings prefixed with a 2 byte header. Example:
|
||||
* int serialNumberDescriptor[] = {
|
||||
* USB_STRING_DESCRIPTOR_HEADER(6),
|
||||
* 'S', 'e', 'r', 'i', 'a', 'l'
|
||||
* };

/*
|
||||
Hardware Prerequisites:
|
||||
=======================
|
||||
USB lines D+ and D- MUST be wired to the same I/O port. We recommend that D+
|
||||
triggers the interrupt (best achieved by using INT0 for D+), but it is also
|
||||
possible to trigger the interrupt from D-. If D- is used, interrupts are also
|
||||
triggered by SOF packets. D- requires a pull-up of 1.5k to +3.5V (and the
|
||||
device must be powered at 3.5V) to identify as low-speed USB device. A
|
||||
pull-down or pull-up of 1M SHOULD be connected from D+ to +3.5V to prevent
|
||||
interference when no USB master is connected. If you use Zener diodes to limit
|
||||
the voltage on D+ and D-, you MUST use a pull-down resistor, not a pull-up.
|
||||
We use D+ as interrupt source and not D- because it does not trigger on
|
||||
keep-alive and RESET states. If you want to count keep-alive events with
|
||||
USB_COUNT_SOF, you MUST use D- as an interrupt source.
|
||||
|
||||
As a compile time option, the 1.5k pull-up resistor on D- can be made
|
||||
switchable to allow the device to disconnect at will. See the definition of
|
||||
usbDeviceConnect() and usbDeviceDisconnect() further down in this file.
|
||||
|
||||
Please adapt the values in usbconfig.h according to your hardware!
|
||||
|
||||
The device MUST be clocked at exactly 12 MHz, 15 MHz, 16 MHz or 20 MHz
|
||||
or at 12.8 MHz resp. 16.5 MHz +/- 1%. See usbconfig-prototype.h for details.
|
||||
|
||||
|
||||
Limitations:
|
||||
============
|
||||
Robustness with respect to communication errors:
|
||||
The driver assumes error-free communication. It DOES check for errors in
|
||||
the PID, but does NOT check bit stuffing errors, SE0 in middle of a byte,
|
||||
token CRC (5 bit) and data CRC (16 bit). CRC checks can not be performed due
|
||||
to timing constraints: We must start sending a reply within 7 bit times.
|
||||
Bit stuffing and misplaced SE0 would have to be checked in real-time, but CPU
|
||||
performance does not permit that. The driver does not check Data0/Data1
|
||||
toggling, but application software can implement the check.
|
||||
|
||||
Input characteristics:
|
||||
Since no differential receiver circuit is used, electrical interference
|
||||
robustness may suffer. The driver samples only one of the data lines with
|
||||
an ordinary I/O pin's input characteristics. However, since this is only a
|
||||
low speed USB implementation and the specification allows for 8 times the
|
||||
bit rate over the same hardware, we should be on the safe side. Even the spec
|
||||
requires detection of asymmetric states at high bit rate for SE0 detection.
|
||||
|
||||
Number of endpoints:
|
||||
The driver supports the following endpoints:
|
||||
|
||||
- Endpoint 0, the default control endpoint.
|
||||
- Any number of interrupt- or bulk-out endpoints. The data is sent to
|
||||
usbFunctionWriteOut() and USB_CFG_IMPLEMENT_FN_WRITEOUT must be defined
|
||||
to 1 to activate this feature. The endpoint number can be found in the
|
||||
global variable 'usbRxToken'.
|
||||
- One default interrupt- or bulk-in endpoint. This endpoint is used for
|
||||
interrupt- or bulk-in transfers which are not handled by any other endpoint.
|
||||
You must define USB_CFG_HAVE_INTRIN_ENDPOINT in order to activate this
|
||||
feature and call usbSetInterrupt() to send interrupt/bulk data.
|
||||
- One additional interrupt- or bulk-in endpoint. This was endpoint 3 in
|
||||
previous versions of this driver but can now be configured to any endpoint
|
||||
number. You must define USB_CFG_HAVE_INTRIN_ENDPOINT3 in order to activate
|
||||
this feature and call usbSetInterrupt3() to send interrupt/bulk data. The
|
||||
endpoint number can be set with USB_CFG_EP3_NUMBER.
|
||||
|
||||
Please note that the USB standard forbids bulk endpoints for low speed devices!
|
||||
Most operating systems allow them anyway, but the AVR will spend 90% of the CPU
|
||||
time in the USB interrupt polling for bulk data.
|
||||
|
||||
Maximum data payload:
|
||||
Data payload of control in and out transfers may be up to 254 bytes. In order
|
||||
to accept payload data of out transfers, you need to implement
|
||||
'usbFunctionWrite()'.
|
||||
|
||||
USB Suspend Mode supply current:
|
||||
The USB standard limits power consumption to 500uA when the bus is in suspend
|
||||
mode. This is not a problem for self-powered devices since they don't need
|
||||
bus power anyway. Bus-powered devices can achieve this only by putting the
|
||||
CPU in sleep mode. The driver does not implement suspend handling by itself.
|
||||
However, the application may implement activity monitoring and wakeup from
|
||||
sleep. The host sends regular SE0 states on the bus to keep it active. These
|
||||
SE0 states can be detected by using D- as the interrupt source. Define
|
||||
USB_COUNT_SOF to 1 and use the global variable usbSofCount to check for bus
|
||||
activity.
|
||||
|
||||
Operation without an USB master:
|
||||
The driver behaves neutral without connection to an USB master if D- reads
|
||||
as 1. To avoid spurious interrupts, we recommend a high impedance (e.g. 1M)
|
||||
pull-down or pull-up resistor on D+ (interrupt). If Zener diodes are used,
|
||||
use a pull-down. If D- becomes statically 0, the driver may block in the
|
||||
interrupt routine.
|
||||
|
||||
Interrupt latency:
|
||||
The application must ensure that the USB interrupt is not disabled for more
|
||||
than 25 cycles (this is for 12 MHz, faster clocks allow longer latency).
|
||||
This implies that all interrupt routines must either have the "ISR_NOBLOCK"
|
||||
attribute set (see "avr/interrupt.h") or be written in assembler with "sei"
|
||||
as the first instruction.
|
||||
|
||||
Maximum interrupt duration / CPU cycle consumption:
|
||||
The driver handles all USB communication during the interrupt service
|
||||
routine. The routine will not return before an entire USB message is received
|
||||
and the reply is sent. This may be up to ca. 1200 cycles @ 12 MHz (= 100us) if
|
||||
the host conforms to the standard. The driver will consume CPU cycles for all
|
||||
USB messages, even if they address another (low-speed) device on the same bus.

General Description:
|
||||
This file is the 12 MHz version of the asssembler part of the USB driver. It
|
||||
requires a 12 MHz crystal (not a ceramic resonator and not a calibrated RC
|
||||
oscillator).
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!
|
||||
|
||||
|
||||
Timing constraints according to spec (in bit times):
|
||||
timing subject min max CPUcycles
|
||||

General Description:
|
||||
This file is the 12.8 MHz version of the USB driver. It is intended for use
|
||||
with the internal RC oscillator. Although 12.8 MHz is outside the guaranteed
|
||||
calibration range of the oscillator, almost all AVRs can reach this frequency.
|
||||
This version contains a phase locked loop in the receiver routine to cope with
|
||||
slight clock rate deviations of up to +/- 1%.
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
LIMITATIONS
|
||||
===========
|
||||
Although it may seem very handy to save the crystal and use the internal
|
||||
RC oscillator of the CPU, this method (and this module) has some serious
|
||||
limitations:
|
||||
(1) The guaranteed calibration range of the oscillator is only 8.1 MHz.
|
||||
They typical range is 14.5 MHz and most AVRs can actually reach this rate.
|
||||
(2) Writing EEPROM and Flash may be unreliable (short data lifetime) since
|
||||
the write procedure is timed from the RC oscillator.
|
||||
(3) End Of Packet detection (SE0) should be in bit 1, bit it is only checked
|
||||
if bits 0 and 1 both read as 0 on D- and D+ read as 0 in the middle. This may
|
||||
cause problems with old hubs which delay SE0 by up to one cycle.
|
||||
(4) Code size is much larger than that of the other modules.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!
|
||||

General Description:
|
||||
This file is the 15 MHz version of the asssembler part of the USB driver. It
|
||||
requires a 15 MHz crystal (not a ceramic resonator and not a calibrated RC
|
||||
oscillator).
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!

General Description:
|
||||
This file is the 16 MHz version of the asssembler part of the USB driver. It
|
||||
requires a 16 MHz crystal (not a ceramic resonator and not a calibrated RC
|
||||
oscillator).
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!

General Description:
|
||||
This file is the 16.5 MHz version of the USB driver. It is intended for the
|
||||
ATTiny45 and similar controllers running on 16.5 MHz internal RC oscillator.
|
||||
This version contains a phase locked loop in the receiver routine to cope with
|
||||
slight clock rate deviations of up to +/- 1%.
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!

General Description:
|
||||
This file is the 18 MHz version of the asssembler part of the USB driver. It
|
||||
requires a 18 MHz crystal (not a ceramic resonator and not a calibrated RC
|
||||
oscillator).
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!

;max stack usage: [ret(2), YL, SREG, YH, [sofError], bitcnt(x5), shift, x1, x2, x3, x4, cnt, ZL, ZH] = 14 bytes
|
||||
;nominal frequency: 18 MHz -> 12 cycles per bit
|
||||
; Numbers in brackets are clocks counted from center of last sync bit
|
||||
; when instruction starts
|
||||
;register use in receive loop to receive the data bytes:
|
||||
; shift assembles the byte currently being received
|
||||
; x1 holds the D+ and D- line state
|
||||
; x2 holds the previous line state
|
||||
; cnt holds the number of bytes left in the receive buffer
|
||||
; x3 holds the higher crc byte (see algorithm below)
|
||||
; x4 is used as temporary register for the crc algorithm
|
||||
; x5 is used for unstuffing: when unstuffing the last received bit is inverted in shift (to prevent further
|
||||
; unstuffing calls. In the same time the corresponding bit in x5 is cleared to mark the bit as beening iverted
|
||||
; zl lower crc value and crc table index
|
||||
; zh used for crc table accesses
|
||||
|
||||
;--------------------------------------------------------------------------------------------------------------
|
||||
; CRC mods:
|
||||
; table driven crc checker, Z points to table in prog space
|
||||
; ZL is the lower crc byte, x3 is the higher crc byte
|
||||
; x4 is used as temp register to store different results
|
||||
; the initialization of the crc register is not 0xFFFF but 0xFE54. This is because during the receipt of the
|
||||
; first data byte an virtual zero data byte is added to the crc register, this results in the correct initial
|
||||
; value of 0xFFFF at beginning of the second data byte before the first data byte is added to the crc.
|
||||
; The magic number 0xFE54 results form the crc table: At tabH[0x54] = 0xFF = crcH (required) and
|
||||
; tabL[0x54] = 0x01 -> crcL = 0x01 xor 0xFE = 0xFF
|
||||
; bitcnt is renamed to x5 and is used for unstuffing purposes, the unstuffing works like in the 12MHz version
|
||||
;--------------------------------------------------------------------------------------------------------------
|
||||
; CRC algorithm:
|
||||
; The crc register is formed by x3 (higher byte) and ZL (lower byte). The algorithm uses a 'reversed' form
|
||||
; i.e. that it takes the least significant bit first and shifts to the right. So in fact the highest order
|
||||
; bit seen from the polynomial devision point of view is the lsb of ZL. (If this sounds strange to you i
|
||||
; propose a research on CRC :-) )
|
||||
; Each data byte received is xored to ZL, the lower crc byte. This byte now builds the crc
|
||||
; table index. Next the new high byte is loaded from the table and stored in x4 until we have space in x3
|
||||
; (its destination).
|
||||
; Afterwards the lower table is loaded from the table and stored in ZL (the old index is overwritten as
|
||||
; we don't need it anymore. In fact this is a right shift by 8 bits.) Now the old crc high value is xored
|
||||
; to ZL, this is the second shift of the old crc value. Now x4 (the temp reg) is moved to x3 and the crc
|
||||
; calculation is done.
|
||||
; Prior to the first byte the two CRC register have to be initialized to 0xFFFF (as defined in usb spec)
|
||||
; however the crc engine also runs during the receipt of the first byte, therefore x3 and zl are initialized
|
||||
; to a magic number which results in a crc value of 0xFFFF after the first complete byte.
|
||||
;
|
||||
; This algorithm is split into the extra cycles of the different bits:
|
||||
; bit7: XOR the received byte to ZL
|
||||
; bit5: load the new high byte to x4
|
||||
; bit6: load the lower xor byte from the table, xor zl and x3, store result in zl (=the new crc low value)
|
||||
; move x4 (the new high byte) to x3, the crc value is ready

General Description:
|
||||
This file is the 20 MHz version of the asssembler part of the USB driver. It
|
||||
requires a 20 MHz crystal (not a ceramic resonator and not a calibrated RC
|
||||
oscillator).
|
||||
|
||||
See usbdrv.h for a description of the entire driver.
|
||||
|
||||
Since almost all of this code is timing critical, don't change unless you
|
||||
really know what you are doing! Many parts require not only a maximum number
|
||||
of CPU cycles, but even an exact number of cycles!

General Description:
|
||||
This header is intended to contain all (or at least most of) the compiler
|
||||
and library dependent stuff. The C code is written for avr-gcc and avr-libc.
|
||||
The API of other development environments is converted to gcc's and avr-libc's
|
||||
API by means of defines.
|
||||
|
||||
This header also contains all system includes since they depend on the
|
||||
development environment.
|
||||
|
||||
Thanks to Oleg Semyonov for his help with the IAR tools port!
