题目：基于52单片机数字时钟设计 学 院 专 业 姓 名 班 级 学 号 指导教师 起讫时间 基于AT89C52单片机数字时钟设计 [摘要] 时间是科学技术和日常生活中最基本的物理量之一，随着科技的快速发展和生活水平的不断提高，人们对时钟的精准度和实用性要求越来越高。本文基于单片机技术原理，以单片机AT89S52作为核心控制器，通过硬件电路的制作以及软件程序的编制，设计制作出一个数字时钟系统。 本文主要介绍一种基于AT89C52 单片机和1062液晶显示器的六位数字时钟，具有操作简单，显示明了，功能强大的特点。有三个按键，可以调时校对的功能。 该电路系统采用AT89C52单片机作为核心，功耗小，能在5V的低压工作。本设计采用的Keil编译系统是现在使用比较多的ARM编译系统。与ADS编译系统相比，Keil编译系统不需要模版，自动生成启动文件，且Keil For Arm编译系统可以与Proteus联机，这一点在虚拟开发中是非常实用的。 本文从硬件电路到单片机控制器再到微处理器程序进行了一系列的设计，最终将各模块整合到Proteus中进行仿真，最终在Proteus中仿真的结果令人满意。 关键词 AT89C52单片机 ；1602液晶 ；Keil编译系统；Proteus仿真 The implementation of digital clock with AT89C52 single chip computer Author :付宁波 Teacher:程娅荔 [Abstract]Time is one of the most fundamental physical quantities in science and technology and daily life. With the rapid development of science and technology and living standard , human beings are increasingly demanding of the accuracy and practicability of the clock . With reference to the analysis of the demand of the function of the clock in peoples daily life, and with the single-chip microcomputer technical principal , and by considering the AT89S52 single-chip computer as the core controller as well as the design of hardware circuit and the programming of software, a digital clock system can be designed and made This paper mainly introduces a method based on AT89C52 single chip computer and 1062 LCD digital clock, has six operation is simple, show clear, powerful features. There are three key, can you adjust the function of when checking. This circuit system adapts the AT89C52 single-chip computer as core, which has the advantage of low power. Therefore, it can work under the circumstance of low voltage of 5 ， This design uses the Keil for ARM compiling system , which now is used widely. Compared with ADS compiler system, Keil compiler syste
