I am using an Arduino Due with an Ethernet shield.
I get a compiler error when i add the ArduinoModbus.h library, I have read someone said Arduino Due doesnt work with this library, but i havent found any confirmation on this.
I am trying to use my Arduino due as a ModBus TCP server.
Arduino: 1.8.16 (Windows Store 1.8.51.0) (Windows 10), Board: "Arduino Due (Programming Port)"

Error compiling for board Arduino Due (Programming Port).
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I have also tried in the web-editor. With ArduinoModbus library with the Arduino Due, still error when trying to compile. Must be that the library isnt compatible with the DUE?
