LedStrip.h

00001 // Parent class for all addressable LED strips.
00002 // Partially based on work by and (c) 2011 Jelmer Tiete
00003 // whose library is ported from the Arduino implementation of Adafruit Industries
00004 // found at: http://github.com/adafruit/LPD8806
00005 // and their strips: http://www.adafruit.com/products/306
00006 // Released under the MIT License: http://mbed.org/license/mit
00007 
00008 // This is a pure virtual parent class for all LED strips, so that different types
00009 // of strip may be used in a single array or container.
