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.

Library Manager Install the library into your Arduino IDE using the Library Manager (available from IDE version 1.6.2). Open the IDE and click Sketch > Include Library > Manage Libraries… Scroll or search forModbusMaster, then select the version of the library you want to install. Quit/re-...
modbus-esp8266: Most complete Modbus library for Arduino. A library that allows your Arduino board to communicate via Modbus protocol, acting as a master, slave or both. Supports network transport (Modbus TCP) and Serial line/RS-485 (Modbus RTU). Supports Modbus TCP Security for ESP8266/ESP...
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...
