以AT89S52单片机为心_设计出功能较强的新型单片机实验系统毕业设计.doc

摘 要 目前单片机应用已渗透到各个领域，单片机技术的发展也因此日新月异传统的单片机实验系统，需要频繁拔插烧写单片机芯片来编程，依赖于仿真机调试，实验成本高且效率低.，已不适应现代科技开发需求。本文从微处理器、嵌入式系统和C语言等三个方面着手，以AT89S52单片机为核心，设计出功能较强的新型单片机实验系统。以AT89S52为核心，设计出12种实验的原理图。采用电子CAD(PROTEL99SE软件)、Proteus等软件。利用C语言调整软件dev C++IDE、编译器Keil C（uVision-51）软件等技术创新，实现了Proteus仿真调试功能，将嵌入式技术融入到单片机实验系统开发与应用中极大地提高了程序开发的效率，达到优化单片机实验系统功能的目的。微处理器 嵌入式系统 AT89S52单片机 实验系统调试与仿真 ProteusAt present the monolithic integrated circuit ( Microcontroller Unit,MCU) applications have penetrated into all fields. The traditional monolithic integrated circuit experiment system, needs frequently to pull out inserts the fever to write the monolithic integrated circuit chip to program, relies on to the simulation machine debugging, The experimental cost high also the efficiency is low, already unsuitable modern science and technology development demand. This article from the microprocessor, Embedded Systems and the C language and so on three aspects begins, to draw up take the AT89S52 monolithic. integrated circuit as a core, designs the function stronger new monolithic integrated circuit experiment system. Took AT89S52 as the core, Designed 12 experiments. After uses electronic CAD (PROTEL99SE software), Proteus software.Using C language adjustment software dev C++IDE, compiler K.eil C (uVision-51) and, technical innovation and so on Proteus software, has realized the Proteus on-line simulation debugging function, Inserts the embedded technology to melt into to in the monolithic integrated circuit experiment system development and the application. Key words:Microprocessor; Embedded Systems;AT89S52 MCU; Experimental system;Debugging and simulation;Proteus目 录 摘 要 I Abstract II 第一章 概述 1 第二章 Proteus 介绍 3 2.1 Proteus的工作过程【2】 3 2.2 用Proteus软件虚拟单片机实验的优点 4 2.3 本章小结 4 第三章 单片机介绍 6 3.1 功能特征描述 6 3.2 引脚功能【4】 6 3.3 存储器结构 9 3.3.1 程序存储器 9 3.3.2 数据存储器 9 3.4 看门狗定时器 9 3.4.1 WDT的使用 10 3.4.2 掉电和空闲方式下的WDT 10 3.5 UART 10 3.6 定时器0 和定时器1 10 3.7 定时器2 11 3.7.1 捕捉方式 11 3.7.2 自动重载【6】 11 3.8 波特率发生器 12 3
