ESP32 Programming using Arduino IDE: In the Arduino IDE, you can upload the provided code to your ESP32 board. This code utilizes the SoftwareSerial library to interact with the Modbus device. Ensure that the baud rate in the SoftwareSerial configuration matches the transmitting device’s baud ...
Unzip the library and copy the main folder into the "Libraries" folder in the folder you installed your Arduino software. Eg. C:\arduino-1.0.3\libraries\ Rename the folder to "RS485" (This will stop the Arduino IDE from complaining about the long folder name) ...
