The serial serial_config.json file contains the settings for the serial interface which is used to communicate with the DGUS Display.

Currently it contains only a single configuration option.

{
   "com_interface": {
      "serial_port": "/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0"
   }
}

serial_port needs to be adapted to match the tty inteface created for your USB-TTL adapter.

If your USB TTL was detected properly it should be listed under /dev/serial/by-id

$ ls /dev/serial/by-id/
