Research on USB Interface Data Communication Method Based on STM32

数据传输是数据通信过程中必不可少的环节。传统的单片机与PC机之间的数据传输,通常采用串口、I2C等通信方式,这些方式存在传输速度低、传输距离受限,接口连接复杂等不足。本文基于STM32提出了一种USB接口的数据传输方法,通过PC端传输数据到单片机,实现了指示灯的开关控制。经试验验证,该方法传输速率高、传输稳定、安全性高,具有很好的应用价值。

Data transmission is an essential link in the process of data communication.The traditional data transmission between single chip microcomputer and PC usually adopts serial port,I2C and other communication methods.These methods have the disadvantages of low transmission speed,limited transmission distance and complex interface connection.Based on STM32,this paper proposes a data transmission method of USB interface,which transfers data to MCU through PC,and realizes the switch control of indicator light.The experimental results show that the method has high transmission rate,stable transmission and high security,and has good application value.
