该项目是数字时钟的使用RTC DS12C887和8051微控制器（AT89C51）与时间设定，我们可以将它设置闹铃唯一不同的改进版本。它有助于理解在RTC的12C887设定报警的概念。该方案采用两个外部中断0和1，分别设定时间和闹铃。用于设置时间销P3中的微控制器8051的^2由低，这是外部中断0。对于报警设置微控制器的引脚P3.3由低是外部中断1。

常用EEPROM芯片的读写操作，51单片机控制电路，实验时要用74LS373一片，AT28C16一片，AT28C17一片，电路十分简单，根据实际电路联接情况，自行确定存储地址，最后别忘了还要8个LED和470欧姆电阻.-EEPROM chip used to read and write operations, 51 MCU control circuit, experiment, use 74LS373 1, AT28C16 1, AT28C17 1, the circuit is very simple, based on the actual situation of the circuit connectivity, self-determined memory addresses, finally do not forget to also 8 LED and 470 ohm resistors.
