INTRODUCTION:
The scripts in this directory try to work according to the KISS principle. It
contains a script which redirects its stdin to serial device
(send_to_serial.py), one that simulates the ledbar and sends the data unaltered
from its stdin to its stdout, a module that helps programmers to program
various graphical effects and some example effect generators using this module.
EXAMPLES:
./rainbow.py | ./demo.py >/dev/null
- only simulate the rainbow effect, do not send it anywhere
./rainbow.py | ./send_to_serial.py
- only send the data to the serial device, do not show the simulation
./rainbow.py | ./demo.py | ./send_to_serial.py
- combine both options, show a simulation and send the data to the serial
device
DEPENDENCIES:
demo.py requires PyGame, Python wrapper around SDL
send_to_serial.py requires PySerial, Python library for work with serial ports
equalizer.py requires PyAudio (wrapper around PortAudio) and a microphone
