F2812实验程序，8位键控蜂鸣器与lcd-F2812 experimental procedure, eight keying buzzer sounded with the lcd

利用8255可编程并行口做一个扫描键盘实验，把按键输入的键码，显示在由8279控制的七段数码管上。8255PA口做键盘输入线，PB口作扫描线-8255 programmable parallel port using a scanning keyboard to do the experiment, the button input keys code, displayed in the control of the team respectively by 8279 digital tube. 8255PA I make the keyboard input line, PB mouth for scan line

提供了键盘的扫描码目录，可以通过查询实现相关热键的拦截。-Provides a keyboard scan code directory, can be achieved by querying the relevant hotkey to intercept.
