摘要
该电子钟使用12MHZ晶振与单片机AT89C51相连接,通过软件编程的方法实现了以24小时为一个周期同时显示小时,分钟和秒的要求,并在计时过程中具有报时功能,当时间到达整点进行蜂鸣报时。该电子钟设有三个按键:S1,S2和S3键,使之具备了校时、定时功能。
This electron clock is connected to the MCU AT89C51 by the 12MHZ crystal oscillator. With software programming, the clock can display hour, minute and second at the same time in a 24 - hour cycle. It can give correct time with a buzzer when it is on the hour. This kind of electron clock is equipped with three keys, S1, $2 and $3, which enable the clock to adjust to keep accurate time and to buzz at the set time.
