Peter Emil Jensen / NeoStrip

Library for controlling a strip of Adafruit NeoPixels with WS2812 drivers. Because of the strict timing requirements of the self-clocking data signal, the critical parts of code are written in ARM assembly. Currently, only the NXP LPC1768 platform is supported. More information about NeoPixels can be found at http://learn.adafruit.com/adafruit-neopixel-uberguide/overview

Fork of NeoStrip by Allen Wild
