Description: 8255A控制步进电机汇编程序
步进电机作为执行器件，广泛用于自动控制系统、印字位置的控制及XY记录仪的无关控制等各个领域，而步进电机最适宜于用微处理器来控制，此法应用于实验教学、科研中效果良好。
1、实现全数字化驱动电路
设计思路是采用步进脉冲分配器专用芯片PMM8713和程序计数器8253的方法。图1是采用可编程计数器8253、8255和PMM8713芯片的全数字控制方式接线图。在单片机系统中，只连接8253、8255和PMM8713各一个。

课题六：数字闹钟
1. 通过8253定时器产生秒脉冲定时中断。在中断服务程序中实现秒、分、小时的进位（24小时制）。
2. 将当前时分秒在七段LED显示器上显示（如：091132）。
3. 可设置闹钟的时间当前值（对准时间）,设置闹铃时间,闹铃功能的关闭和开放.
关键词:数字闹钟，8253定时器，LED显示器，8255A并行口
