基于AT89S52单片机的数字时钟设计

Design of Digital Clock Based on AT89S52 Single-chip Microcomputer

设计并实现了一种利用AT89S52单片机的数字时钟。使用时钟芯片产生时间脉冲,并以此脉冲信号作为数字时钟的基准时间信号。利用按键实现对日期、时间等参量的切换与调整,并通过液晶显示日期、时间等参量的当前值,同时具有整点报时功能。

The digital clock is designed and realized by an AT89S52 SCM,using the clock chip produced the clock pulse as the base time of the digital clock.Keys are realized to switch and adjust parameters of date and time.Through the liquid crystal displayed the current value of date and time,meanwhile,the digital clock has the function of ZDTIME.
