摘　　要：USB接口速度快、接口简单、占用CPU资源少,但其复杂的协议却严重阻碍了USB接口应用系统的快速开发与实现。论文针对Microchip公司USB接口系统固件框架,基于控制传输状态机重点解析了事务完成中断驱动的建立、数据、状态三个阶段相关事务处理程序设计技术,研究了基于HID类设备的用户I/O程序设计技术、基于C#.NET的上位机软件开发技术等,在PROTEUS仿真平台测试分析了以PIC18F4550微控制器为核心的USB接口应用系统,为USB接口应用系统开发与实现提供了重要模式与途径。USB interface has the advantages of high speed, simple form and less CPU resource occupation, hut its complex protocol se- riously hindered the rapid development and implementation of USI3 interface application system. According to the Microchip USB interface system firmware frameworks, it focused on the research of transaction process program design technique of setup, data, status stage which driving by transaction completion interruption, and research on the users I/O programming technology based on HID class device, and host computer＇s C#. NET software development technology, etc. It tests and analysis the USB interface application system which take the PIC18F4550 microcontroller as the core in the PROTEUS simulation platform. The research for the USB interface application system devel- opment and implementation provide important models and approaches.
