摘要
用单片机来设计数字钟,软件实现各种功能比较方便.但因软件的执行需要一定的时间,所以就会出现误差.对比实际的时钟,查找出误差的来源,并作出调整误差的方法,使得误差尽可能地小,使得系统可以达到实际数字钟的允许误差范围内.
It＇s very convenient to use a SCM to design a digital clock with software. But the error will easily come out with the time run by software. To contrast with the real clock and find the reason which cause the error and give the arithmetic which can minimize error,then lets the clock meet the need of production.
