- 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

- 动态扫描显示接口 动态扫描显示接口是单片机中应用最为广泛的一种显示方式之一。其接口电路是把所有显示器的8个笔划段a-h同名端连在一起,而每一个显示器的公共极COM是各自独立地受I/O线控制。CPU向字段输出口送出字形码时,所有显示器接收到相同的字形码,但究竟是那个显示器亮,则取决于COM端,而这一端是由I/O控制的,所以我们就可以自行决定何时显示哪一位了。而所谓动态扫描就是指我们采用分时的方法,轮流控制各个显示器的COM端,使各个显示器轮流点亮。-dynamic scan displa
