摘　　要：本文给出了一种基于USB1.1总线协议的嵌入式数据传输系统的设计与实现方案。采用Philips公司的USB专用芯片PDIUSBD12与微控制器LPC2210构成USB设备,在μC/OS-II操作系统上实现该设备的USB通信协议。在PC主机上完成了基于WINDOWS驱动程序模型(WDM)的USB主机驱动程序和应用软件的设计,实现了设备与PC主机的通信。经测试,该USB数据传输系统具有速度快、即插即用、热插拔和低功耗等特点。This paper introduces the design and realization of the data transmission system based on USB Specification 1.1. The USB device was built using the USB dedicated chip PDIUSBD12 and MCU LPC2210 of Philips, and the USB driver program is depicted based on the μC/OS-Ⅱ operation system. The USB host driver using of the WDM and the application software were built on PC, communication between device and PC was realized. The tested results show that the data transmission system has the characteristics, such as high speed, plug and play, hot swap and low-power.
