摘要

这次毕业设计通过对单片机的学习、应用,以AT89S51芯片为核心,辅以必要的电路,设计了一个简易的电子时钟,它主要通过DP-51PROC单片机综合仿真实验仪实现,通过数码管能够准确显示时间,调整时间,它的计时周期为24小时,从而到达学习、设计、开发软、硬件的能力。主要实现功能为显示时间,时间校准调时(采用手动按键调时),闹铃功能(设置定时时间,到点后闹铃发出响声)。通过键盘可以进行校时、定时。闹铃功能使用I/O 口定时翻转电平驱动的无源蜂鸣器。本文主要介绍了工作原理及调试过程。

Abstract

The MCU through graduation learning applications to AT89S51 chip as the core, supplemented by the necessary circuitry to design a simple electronic clock, it is mainly through the DP-51PROC Single Chip Experimental Device to achieve, through the digital control can be accurately show time, adjustment time, it's time period is 24 hours, so get to learn, design, development hardware and software capabilities. Main achieved function to show time, the time when calibration transfer (using the manual button adjustment time), alarm clock (set the regular time, the point to issue after the alarm sound). When the keyboard can be school, regularly. Alarm clock using the I / O port level drivers regularly turn passive buzzer. This paper describes the working principle and the debugging process.

Keywords:MCU electronics clock DP-51PROC
