0到99秒的计时,误差极小,不同一般的DELAY哦.-0-99 seconds of the time, the error is very small and different from other DELAY oh.

用8255,8253,8259实现的具有显示时分秒的电子时钟.-With 8255,8253,8259 realize is displayed every minute with an electronic clock.

此打字游戏采用取系统时间生成随机数来完成的,打开letter.exe文件,输入1则进入游戏 输入2,选择游戏难度 3或Ese退出游戏. -This typing game check the system time used to generate random numbers to be completed and opened letter.exe document, enter an input into the game 2, or 3 to choose the game difficulty Ese exit the game.

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
