// The coding in notpike's script is quite complex, using multiple LUTs to form the data sent to the YSO.
// The format is actually very simple if it is rather seen as short and long gaps between pulses (as seen in many OOK remotes).
// The frames and data rate suspiciously match the NEC infrared protocol (http://www.sbprojects.com/knowledge/ir/nec.php) without
// the address complement. The exact data rate would be 1786 baud (560us/fragment).
// NotPike: The data rate should be 1786 but the remote was transmitting at 1766
