摘　　要：针对智能仪器中传统RS232通信所存在的问题,提出了一种USB接口技术的应用方案。以USB型单片机C8051F340为硬件平台,介绍了应用系统USB接口的硬件结构及工作原理,给出了USB系统应用的固件程序开发过程,并对主机驱动程序和应用程序设计作了简单说明。This paper presents a new applied scheme of the USB interface technology, in order to solve the problem of the conventional RS232 communication in intelligent instrument by taking the C8051F340 MCU with USB function controller as hardware platform. The hardware structure and the working principle of the USB interface technology are described. The design process of a firmware program for the USB system is also given. The paper gives a brief introduction about the designing of both the USB driver and the application program.
