使用485串口进行调试，利用上位机和单片机之间通信-Use 485 serial port for debugging

基于STM32F103C8T6单片机的串口485通讯(MODBUS协议)实现多块板子间的开关量采集与控制采集-Based on STM32F103C8T6 single-chip serial communication 485 (MODBUS protocol) to achieve a number of boards between the switch acquisition and control acquisition

易语言485通讯，完善测试,有需要的人拿去用吧(Easy language 485 communication, improve the test, there are people need to use it)

易语言编写的485串口测试软件软件,可进行固定分辨率测试或者全部波特率测试,自动显示测试结果,不使用易语言COM组件,()
