毕业论文 题 目：51系列单片机教学实验板硬件设计 专 业：测控技术与仪器 51系列单片机教学实验板硬件设计 摘 要 在全国高等院校电子信息类专业中，已普遍开设单片机及其相关课程。单片机课程是大中专院校电子类专业实践性、应用性和工程性很强的专业基础课或专业选修课。从加强学生能力培养的要求来看，这类课程仅在课堂上讲授基本原理是不够的，必须在教学中加强实践环节，让学生有足够的实践机会。其中，单片机实验板就是一个很好的学习单片机的工具。 目前，市场上单片机实验板的种类较多。此次设计的实验板的特点是将各种单元电路合理的拼凑在一块大印刷电路板上，构成一个有机的整体。设计中利用Protel99SE软件先设计原理图，然后进行元件封装， PCB出图，最后是制板。它与传统的教学实验板相比有如下的优点：⑴价格低廉⑵使用简单方便，只要有带RS232串口的PC机就能进行实验⑶功能全，基本上具备单片机常用的接口，如数模转换、模数转换、存储器、LED数码管显示、键盘人机接口、串行接口、温度传感器接口等等。采用本仿真开发实验板，可使初学者迅速掌握单片机原理及应用，熟悉汇编语言、单片机C语言。 关键词：单片机；实验板；接口电路；C语言 51 Series Single-chip Teaching Experimental Board Hardware Design Abstract National institutions of higher learning in the professional category of electronic information, has generally been the creation of single-chip and its related programs. Single-chip college is the course professional practice of electronic institutions, applied and engineering foundation for a strong professional or professional elective courses. From the requirements of students capacity-building perspective, such courses are taught only the basic principles of the classroom is not enough, we must strengthen the teaching practice, to allow sufficient opportunity to practice. Among them, single-chip experimental board is a good learning tool for the students. At present, more types of experimental plate in the single-chip market. The designed board is characterized by a variety of units circuit will be reasonable together on a large printed circuit board and then constitute an organic whole. The design make use of Protel99SE software to design schematic diagram, and then packaging components, PCB map, and finally the system board. It compared to the traditional teaching has the following advantages: ⑴ The prize cheap. ⑵ Use it simple, there is as long as RS232 serial port with the PC machines will be able to carry out such experiments. ⑶ Wide features, the board basically has the interface with commonly used single-chip, full-to-analog converter, analog-to-digital con
