单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振，若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-The smallest single-chip system, the two LED digital tube by the serial output driver 164 then two, Lout, Rout output for the left and right channels, SET, ALT0, ALT1 three buttons can also be their own at the beginning of the I/O definition change you want to use the I/O port 12M crystal, if one uses a 89C51 only loaded about 14 songs can be loaded with 89C52 under near 40

crc计算方法之一，适合于有较大ROM或外部存储器的单片机-unicef.org calculation method, one more suitable for external memory or ROM Microcontroller

此程序可以实现两个单片机之间的相互通信；串口采用方式1工作，10位异步接受和发送，波特率可变，由定时器1控制；且含有校验-This program can be achieved between the two microcontrollers communicate with each other serial port mode 1 using the work of 10-bit asynchronous receive and send, variable baud rate, from Timer 1 control and contains a checksum
