ModbusSlave library for Arduino This Modbus RTU slave library uses callbacks to handle modbus requests for one or multiple slave ids. Handler functions are called on modbus a request, and the users can implement them within their sketch.

在Arduino IDE中，可以通过Sketch->include library->Add .zip Library的方式来添加这个库。完成电路连接并编写好代码后，将代码上传到Arduino Uno。随后，将USB转RS-485模块连接到安装了Modbus Slave软件的计算机上，确保正确的COM端口和协议参数设置。在软件中，选择串行端口作为连接方式，并确保和USB转RS-485模块的...
GitHub - andresarmento/modbus-arduino: A library that allows your Arduino to communicate via Modbus protocol, acting as a slave (master in development). Supports serial (RS-232, RS-485) and IP via Ethernet (Modbus IP). prof (at) andresarmento (dot) com ...
在Arduino IDE中,点击“上传”按钮编译并上传程序到ESP32。 使用Modbus主站工具(如Modbus Poll)测试与ESP32的Modbus RTU Slave通信。通过以上步骤,你应该能够成功地在ESP32上实现一个Modbus RTU Slave程序。如果遇到任何问题,请确保检查串口连接、波特率设置以及Modbus地址等配置是否正确。
Master电路连接完成后，将代码上传到Arduino Uno，现在可以将USB转RS-485模块连接到安装了Modbus Slave...
