This example shows how to use the USB driver to implement a CDC class USB peripheral.

To run this example, you must attach a USB cable to the board. See
|
|
||||||
the "Getting Started Guide" appendix for details.
|
|
||||||
|
|
||||||
How to use:
|
|
||||||
Click the debug toolbar button.
|
|
||||||
Click the go button.
|
|
||||||
Plug the LPCXpresso's target side into a PC using a USB cable retrofit
|
|
||||||
or a 3rd party base board.
|
|
||||||
|
|

|
* Created on: Jan 30, 2011
|

|
* Author: Jan Axelson
|
||||||
|
*
|
||||||
|
* Demonstrates communicating with generic HID-class USB devices
|
||||||
|
* using libusb-1.0 (libusb.org).
|
||||||
|
* Sends and receives 2-byte reports.
|
||||||
|
* Requires: an attached HID-class device that supports 2-byte
|
||||||
|
* Input, Output, and Feature reports.
|
||||||
|
* The device firmware should respond to a received report by sending a report.
|
||||||
|
* Change VENDOR_ID and PRODUCT_ID to match your device's Vendor ID and Product ID.
|
||||||
|
* See Lvr.com/hidpage.htm for example device firmware.
|
||||||
|
* This firmware is adapted from code provided by Xiaofan.
|
||||||
|
* Note: libusb error codes are negative numbers.
|
||||||
|
* Compile with the -lusb option.
