摘　　要：使用STM32单片机进行多串口通信,采用虚拟串口软件(VSPD)结合串口调试软件进行多串口通信发送和接收功能的仿真测试研究,克服了RealView软件不能仿真接收通信的缺点。介绍了虚拟串口和仿真串口的绑定方法,给出了各模块的软件代码。仿真测试结果表明,采用该方法,可以在没有硬件平台的情况下,完成基于STM32多串口收发通信的软件开发应用。The paper uses the STM32 MCU to accomplish the multi-USART communication. It makes use of the VSPD software and USART debugging software to finish the serial communication for sending and receiving, and it overcomes the shortcoming of RealView software which can not simulate the receiving communication. The paper introduces the method of binding dummy USART and simulation USART, and gives the software codes of all modules. The simulation experimental results show that the technology can complete the software development and application based on the STM32 multiport serial transceiver communications in the absence of the hardware platform.
