'''NOTE:''' on some versions of Ubuntu, the default installed Arduino IDE / java interface is broken so that the IDE will not detect the serial port and allow the board to be programmed. The solution is installed the Arduino ide as a flatpack, or manually. The Arduino binary must be added to the path in order to be found by arduinosetup. Alternatively, the full path/binary for the ide can be specified to arduinosetup. | |||
