Data Acquisition Design Based on the STM32

In the automation industry, the data collection used in the site is the key basic technology to ensure the product quality and normal operation of the production system.With the development of information technology, data acquisition technology is widely used in industry field. High-speed, real-time data acquisition has a very important application in the field of industrial automation.The speed of A/D chip is becoming faster and data acquisition system requires higher transmission speed.Traditional communications style is restricted by the slow transmitting rate,weak anti-jamming ability and will be replaced by USB, the new generation Universal Serial Bus.This thesis analyzed characteristics of Universal Serial Bus and the requirement of data acquisition system based on USB. Lastly, a data acquisition system based on STM32 MCU was designed.
