Xiong Kaisheng

Abstract

With the popularization and development of USB(Universal Serial Bus) interface,how to make use of the USB interface to realize data collection now becomes a hotspot of research and development.Realization concept of data collection system based on USB and implementation with microprocessor with embedded USB interface are presented and the hardware design and software development are discussed.On the part of hardware design,this article provides three schemes and introduces one among this three schemes in detail.On the part of software development,this article introduces the USB firmware design,USB device drive program design and application program design in detail.
