1. Abstract
The system uses MCU AT89S52 as its central part. The periphery circuits mainly include clock module, keyboard module, liquid crystal display module and stop watch and counting down the important day. This kind of electronic clock not only has basic function of the general digital clock, but also have the following function: the alarm clock time establishment, demonstrating the calendar, the stop watch, counting down the important day, and so on. The system uses the serial clock chip DS1307, to realize the display of time establishment and alarm clock. To proofread the clock and the establish alarm clock time conveniently, we can use liquid crystal display and the keyboard .We can also complete stop watch and counting down the important day by using the MCU interruption system.The overall system carries on the programming by using MCU C51 language, and realizes its each design function.
Key Words: MCU Clock chip Liquid crystal display(LCD) C51 language
