摘　　要：在工业控制应用中,串口是微控制器系统必不可少的接口之一,但是串口在应用过程中容易出现误码现象,需要对接收的数据进行校验才能保证通信的可靠性。本文提出一种基于STM32F107的可靠串口通信设计方案,STM32F107提供5个独立的异步串行接口,并且内置了CRC计算单元,实践表明具有较好的性能。The serial port is one of the indispensable interface for microcontroller systems in industry control applicaton. However, the serial port in the application process is easy to appear error phenomenon, so it need to check the received data to ensure the reliability of communication. A reliable serial communication design based on STM32F107 is designed in this paper, STM32F107 provides five independent asynchronous serial interfaces and built-in CRC calculation unit, and the experimental result shows that the design has better performance.
