基于单片机控制的串行口调时时钟设计

The Design of Serial Port Debugging Clock Based on Single Chip Microcomputer

介绍了单片机的串口通信方式和时钟中断定时方法,采用89S52的定时器0中断实现时钟秒、分、时的控制,使用单片机的串口通信中断对时钟进行调节,设计了硬件电路,编写了软件程序,实现了计算机对时钟的实时控制。

This paper introduces serial communication mode and interrupt timing method of single chip microcomputer, that is to realize the control of the seconds, minutes and hours of clock by using 89S52 timer＇s 0 interrupt and to adjust the clock by using serial communication interrupt of single chip microcomputer, designs the hardware circuit, and writes the software program, realizing the real-time control of computer to the clock.
