In order to amend the firmware you will need to do the following…
- Expand the zip file emailed to you -> to a folder with the same name as the zip file.
- Download the Arduino IDE from https://www.arduino.cc/en/Main/Software
- Find and download the CH340G driver for your machine ( if its Linux, I think it part of the kernel ). For windows I usually follow this route… http://forum.arduino.cc/index.php?topic=397368.0
- Once downloaded and installed, open the IDE
- Open the Sketch [DCC_PremierKit_A4988_NANO.ino] that is in the unzipped file.
- You don’t need to amend the [DCC_PremierKit_A4988_NANO.ino] file – most of what you need to do is in [configuration.h]
- Install the NMRA and AccelStepper libraries from the [Manage Libraries….] menu item
- Set the board to a “Arduino Nano” from the Tools->Boards Menu
- Plug your Arduino in to your computer – the ch340g driver should show it up as a COM port.
- Change the COM port from the “Tools” menu
- Click “Verify” to make sure everything is building.
- Click Upload to upload the new Firmware to the DCC Controller. The IDE will inform you once its complete.
