串行驱动led显示- Serial actuates led to demonstrate

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

针对51单片机的中断触发按键的程序，利用P3.2口接行列按键。-For 51 single-chip key interrupt to trigger the process, I then use the ranks of P3.2 button.
