毕 业 论 文 题目：基于STM32的逻辑分析仪 计与实现 学院： 机电工程学院 专业： 电气工程及其自动化 摘 要 当前电子技术的不断发展，电子工程师们在研发新的电子产品过程中，都要经过不断的修改产品的参数，使得新产品的性能比以往的更加可靠、安全、经济等要求。当然在此过程中，调试无疑是最麻烦的，因为现在的产品设计都是越来越复杂，而在数据域测试的领域中，大多数情况下只在意数据信号之间的逻辑关系。为此，本文介绍基于STM32的逻辑分析仪的实现。设计中采用ST公司的STM32处理器搭建下位机平台，下位机采集各点的电平，以及通过STM32系列的USB接口部件，与上位机构成通信，把采集的数据及时发送给上位机，在上位机上用图形界面显示各个通道采集到的电平。整个设计过程中，主要的问题有根据USB2.0的协议以及HID协议、CDC类协议等将STM32系列处理器USB接口部件配置成适当的USB设备，上位机图形界面的程序设计以及基于Windows XP下USB驱动的设计等。 关键词：STM32；VC图形界面设计；VC与串口通信；Windows XP下USB驱动的设计 Abstract The current electronic technology unceasing development, electronic engineers in developing new electronic product process, need to pass unceasing revision, and that make the product performance of a new product than ever more reliable, safe, economic and so on. Of course during the process, debugging is undoubtedly the most troublesome, because now the product design is more and more complicated, and in the data field tests in the field, in most cases only care about the logic relation between data signals. Therefore, this paper introduces the realization of the logical analyzer based on STM32. The design use the STM32 processor of ST company to build lower level computer platform, lower level computer acquisition at various points, and through the USB interface components of STM32 processor,and the upper agencies into the collection of data communication, timely send to PC, with the graphical injunction interface on the collection to show each channel level. The whole design process, the main problems is the agreement and HID according to USB2.0 agreements, the CDC type of agreement will be STM32 series processor USB interface components configuration into the appropriate USB devices, PC graphics and design of the interface of the program based on Windows XP USB driver design under etc. Key wards: STM32；VC graphical interface design; VC and serial interface communication; driver design under Windows XP; 目录 1 绪论 1 1.1 课题研究背景 1 1.2 课题研究意义和前景 1 1.3 国内外现状 1 1.4 课题研究的内容
