STM32单片机多串口通信仿真测试技术研究

摘要

To address the issue of software design and test without hardware platform,the paper uses a STM32 MCU to accomplish multi⁃USART communication,and uses VSPD software and USART debug software to accomplish the transmitting and receiving function simulation of multi⁃USART communication.The method overcomes the RealView software’ s disadvantage of not being able to simulate receiving communication.The paper also introduces the method of binding simulated USART and virtual USART,and gives the software codes of all modules.The simulation results show that the development and test of multi⁃USART transmitting and receiving communica⁃tion software can be accomplished without hardware platform.%为了解决在没有硬件平台情况下进行软件开发和测试的问题，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。
