I am using Controllino-Maxi for controlling a machine, and it functions very well. Now, finishing the project, I would like to back-up the Arduino-IDE in it’s current revision, with all necessary files locally stored. This includes the “Controllino Board-Vervalter”-file. I have therefore copied the Controllino json file from GITHUB, and in the IDE Presets “Zusätzliche Boardverwalter URLs” written the path: file:///C:/trash_arduino/package_ControllinoHardware_index.json
I then expected the Controllino hardware to be listed under Boards, but this is not the case, and I therefore get a compiler error.
What can be the reason? Have I written the path in a wrong format?
