单片机的电子时钟：6个数码管分时循环工作，刷新频率≥25Hz。键盘采用矩阵式电路，L1-L4作为输出，H1-H4作为输入。（详细工作原理请参考教材第10章）。 系统时钟采用12MHz，采用定时器方式2计时-SCM Electronic Clock: 6 digital control time-cycle work, refresh frequency ≥ 25Hz. Keyboard, a matrix circuit, L1-L4 as the output, H1-H4 as input. (Details please refer to teaching works Chapter 10). The system clock is 12MHz, using the timer mode 2 time
