课程设计 基于80C51系列单片机教学实验板设计 摘要 单片机由于控制功能强、可靠性高和体积小、价格低等特点，在智能仪器仪表、工业测控、家用电器等领域有非常广泛的应用。因此，几乎每所高校在机电、自动控制、应用电子等工科专业中都开设了《单片机原理与应用》课程。《单片机原理与应用》作为一门实践性很强的课程，必须要有一套合适的单片机实验平台和实验项目来配合教学，才能实现教学目标。 Because of strong control function,high reliability,small volume and low cost,the Microcontroller unit (MCU has broad application prospect in intelligent instruments and apparatus, industrial measuring and controlling system and home appliances.Almost all of universities and colleges provide the MCU course, namely the principle and application of MCU. This course is a practical course, which needs a suit of experimental platform and various contents to support teaching and learning process. 论文根据80C51单片机技术不断成熟和完善，市场拥有量大且快速增长，为各个学校单片机教学的首选机型这一实际情况，设计开发了80C51系列单片机教学实验板。该实验板以建立单片机应用“系统”的概念为主题，从具体应用这一角度切入主题，注重实验的实用性、方便性、经济性、系统性和开放性。 Actually,the 8OC51 MCU is highly accepted in the market and rapidly developed because of its mature and perfect technology, this paper designs a MCU teaching and experimental board by using 80C51 product. 该实验板围绕常用控制系统为主线的各个基本项目的实践教学，以此激发学生对单片机学习和应用的兴趣，让学生掌握单片机的原理和用途，熟悉开发单片机应用系统的流程和方法，初步具有开发简单的单片机应用系统软硬件的能力，达到开设单片机课程的教学目的。 This experimental board primarily realizes the simple controlling system, in order to fulfill the aim of establishing a MCU application system.It focuses on designing practical,convenient,economic, comprehensive and open experiments.The practical teaching of each basis item,which surrounds the simple but practical measure system o f home air-condition system,in spires students interests in learning and using MCU technology, guides the students to master its principle and application, acquaints the flow chart and methods to develop new product That is the creaim of opening the course of MCU technology 目录 第一章 绪论 1.1 选题意义 单片机的诞生标志着计算机正式形成了通用计算机系统和嵌入式计算机系统两个分支。通用计算机系统主要用于海量高速数值运算，不必兼顾控制功能，其数据总线的宽度不断增加，从8位、16位迅速过渡到32位、64位，并且不断提高运算速度和完善通用操作系统，以突出其高速海量数值运算的能力，在数据处理、模拟仿真、人工智能、图像处理、多媒体、网络通信中得到了广泛应用;单片机作为最典型的嵌入式系统，由于其微小的体积和
