摘　　要：通用串行总线(USB)是目前最常用的一种计算机总线。介绍了DSP芯片TMS320VC33与主机之间基于USB总线接口芯片CH372V通信的设计方案,详细描述了TMS320VC33与CH372V的接口电路设计,并对CH372V的通信模式做了介绍,针对数据上传和下传通信程序以及API函数做了系统地说明,采用MFC实现了USB通信的应用程序。设计结果表明,该设计方案硬件成本低,软件开发简单,具有很强的实用性.USB is one of the most popular interfaces connecting peripheral devices to the host system. In this paper, the design of communication between TMS320VC33 and host is introduced based on CH372V. Not only the design of TMS320VC33- ch372V interface circuit is introduced in detail, but also the communication mode of the CH372V is mentioned. The communication program in up-data and down-data are also expounded. API function is explained in system as well. The application of communication is developed with MFC. The practice proves that this design project reduces the cost of hardware, simplifies the software development and is full of common use.
