I’ve put together a list of links that I think are essential to the DCC++ project.
The YouTube videos are excellent and the 4 hardware related ones are all I needed to get my system up and running. The first 3 deal with theory and are very helpful. The 4th is the actual construction instructions.
There is an extensive discussion about DCC++, including further developments of the system available on the Trainboard forum.
The code to load onto the Arduino is available through GitHub:
