摘  要:
This paper researches on a multi-channel data acquisition system based on USB2.0. In the hardware,the STM32F103RB is used as its microcontroller and chose CY7C68013 manufactured by Cypress corporation USB chip.ADS1271 produced by Ti corporation is used as its A/D chip.On this base,Labview8.20 which is a kind of graphical programming language to complete the application design is chosen.This system’s highest sampling rate can reach 80KSPS,it achieves a 18Bit resolution of the 4-channel real-time data collection and can meet the most needs of vast applications.
