It all started when I found the Modbus RTU Arduino library of Juan Pablo Zometa. I had extend the library to support other Modbus functions. After researching several other Modbus libraries I realized strengths and weaknesses in all of them. I also thought it would be cool have a base libra...

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。
