说明：  PIC单片机写的红外遥控接收代码，很经典用定时器和中断一起处理的很高效而且定时器还可以用于别的地方，彻底模块化隔离，已经测试绝对可用！
(PIC microcontroller code written by infrared remote control receiver, classic together with a timer and interrupt handling is very efficient and the timer can also be used somewhere else, completely modular isolation, has been tested absolutely available!)
