51单片机实现遥控解码，通过数码管显示键码的程序，P0口驱动数码管段选，p2.6和p2.7为数码管位选，接收头连到P3.2口。此程序以通过验证，可以直接编译使用，另外还有一个继电器和蜂鸣器的控制，不用可以屏蔽掉。-51 MCU remote control decoding, digital display key code through the program, P0 port drive digital pipe election, p2.6 and p2.7 for the digital control bit selection, receiver connected to the P3.2 port. This process through validation, you can compile using, in addition to a relay and buzzer control, do not be masked.
