摘　　要：针对基于STM32的USB通信中存在通信不稳定与不可靠的不足,提出一种基于FT234XD的串口通信端口设计,可以实现USB通信协议转串口通信协议的转换。该方案首先是上位机通过串口通信向下位机发送指令实现对各硬件模块的参数配置。然后是下位机完成相应操作并将结果反馈给上位机,这样就可以实现上下位机数据交换。其次是避免传输中出现错误,将64bytes的数据打包通过串口通信进行发送,来验证通信的可靠性。最后是将USB转串口通信的端口设计运用到功率放大器中,来测试USB转串口通信具有速度快、稳定性好等优点。Aiming at the instability and unreliability of STM32-based USB communication,a serial communication port design based on FT234 XD is proposed,which can realize the conversion of USB communication protocol to serial communication protocol.In this scheme,the upper computer sends instructions to the lower computer through serial communication to realize the parameter configuration of each hardware module.Then the lower computer completes the corresponding operation and feeds the result back to the upper computer,so that data exchange between the upper and lower computers can be realized.The second is to avoid errors in transmission,packetizing 64-byte data and sending it through serial communication to verify the reliability of communication.Finally,the port design of USB-to-serial communication is applied to the power amplifier to verify that USB-to-serial communication has the advantages of fast speed and good stability.
