 * Copyright 2009 Ken Shirriff
 * For details, see http://arcfn.com/2009/08/multi-protocol-infrared-remote-library.html
 *
 * Edited by Mitra to add new controller SANYO
 *
 * Interrupt code based on NECIRrcv by Joe Knapp
 * http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1210243556
 * Also influenced by http://zovirl.com/2008/11/12/building-a-universal-remote-with-an-arduino/
 *
 * JVC and Panasonic protocol added by Kristian Lauszus (Thanks to zenwheel and other people at the original blog post)
 * LG added by Darryl Smith (based on the JVC protocol)
 * Whynter A/C ARC-110WD added by Francesco Meschia
 * Coolix A/C / heatpump added by bakrus
 * Denon: sendDenon, decodeDenon added by Massimiliano Pinto
