00002 * WiiClassicControllerReader. A program allowing the output of one or two
00003 * Wii Classic Controllers to be read via I2C and decoded for use, using the mbed 
00004 * microcontroller and its associated libraries.

00006 * Written by Alfredo Guerrero <alfredog83@gmail.com> for the mbedGC open-source 
00007 * game console <http://www.mbedgc.com>. Based on the original code for
00008 * the WiiNunchuckReader written by Petras Saduikis <petras@petras.co.uk>.
