红外遥控解码的C51程序，认为是可能是史上最简的。此程序是针对uPD6121系列的遥控器的取码程序，解码值在Im[2]中，当IrOK=1时解码有效。 -C51 infrared remote control decoding procedure may be considered to be the history of the most simple. This procedure is uPD6121 series of remote control codes of the check procedure, decoding value Im [2], when IrOK = 1 when decoding effectively.
