Arduino Interface Library for ITeadStudio Colorduino and Colors Shield Copyright (c) 2011-2016 Sam C. Lin <lincomatic@hotmail.com> To install, copy libraries/Colorduino to your <arduino sketchbook folder>/libraries/Colorduino folder. ColorduinoPlasma.pde is a sample program which uses the library. It displays an animated plasma on an 8x8 LED matrix NOTE: Later versions of Arduino make the library run slowly. It's easy to see because ColorduinoPlasma runs slowly in a step-like version. I'm not sure which version triggers the slowdown, but my testing with Arduino 1.6.3 -> 1.8.1 all exhibit the slowdown. Arduino 1.0.2 runs full speed Modified: Removed the inefficient digitalPinToBitMask() and digitalPinToPort(), which was causing the sketch to run very slow if compiled by later versions of Arduino.
