The Design of USB Data Acquisition System Based on CH371

Xiaoguang Zhang

Abstract

This paper introduced the design of a data acquisition system based on USB which included hardware and software. Due to the CH371 applied in the system, the firmware procedure' program was simplified for carrying out USB message and the time of the system development was shortened. The result shows that it is preferable to meet the demand of data acquisition in lab.
