基于单片机的教学实验开发系统设计与实现

摘要

单片机开发系统是大中专院校电气、电子类等专业实验教学必不可少的设备。但目前大部分的单片机开发系统多是基于应用层面而非硬件底层，这样将不利于该专业的人才培养。通过对开发系统的硬件和软件测试程序的介绍，设计出一种兼容RS232串口和USB下载的，集温度采集、LCD显示以及串口通信等多种功能于一身的开发系统。为单片机系统设计和开发提供了一个硬件平台。%MCU system platform of experimental teaching is one of necessary equipment in college electromcs anu e- lectrics major. But now most of MCU developing system is based on application level rather than hardware level, it will be detrimental to the training in this field. According to an introduction of hardware on the developing system and test program of software, a developing system, which consists of RS232 serial port, USB download, temperature collection, LCD display and serial port communication, was designed. This design provides a hardware platform for the application of MCU in experimental teaching.
