利用实验箱提供的键盘扫描电路和显示电路,做一个扫描键盘和数码显示实验，把按键输入的键码在六位数码管上显示出来

实验程序可分成三个模块。

① 键输入模块：扫描键盘、读取一次键盘并将键值存入键值缓冲单元。

② 显示模块：将显示单元的内容在显示器上动态显示。

③ 主程序：调用键输入模块和显示模块。

-Experimental box provided by the keyboard scanning circuit and display circuit, do a scan keyboard and digital display experiment, the keys to enter the key code on the six digital displays experimental procedures can be divided into three modules. ① key input module: scan the keyboard, reads the keyboard and keys into a key buffer unit. ② Display Module: The content displayed on the display unit of the dynamic display. ③ the main program: call key input module and display module.
