Description: 实现pc机键盘（p/s2接口）与8位单片机连接使用
原理：键盘时钟接在p3.2口，既8051的外部中断int0上，键盘数据接到p1.0上
每次按键，键盘会向单片机发脉冲使单片机发生外部中断，数据有p1.0口一位一位传进来
传回的数据格式为：1位开始位（0），8位数据位（所按按键的通码，用来识别按键），1位校验位(奇校验)
1位结束位(1)
实现：将键盘发回的数据放到一个缓冲区里（数组），当按键结束后发生内部中断来处理所按的按键
缺点：由于51单片机的容量有限所以缓冲区不可以开的太大，这就导致可以记录键盘的按键次数过少，
也就是容错性一般。不过如果正常使用键盘是不会出错的
