Finally had a big breakthrough with the LC Remote. It is now talking to my Gateway board. https://youtu.be/YQC4aA-btDA
Now things are getting exciting!
Next up I will add the remote code to my main program and I will post a new postwar accessory video being controlled from the real remote and not just the app.
Next up I also am going to test a limited way to choose announcements on regular LionChief locos. It won't quite be legacy level of control but it might be better than default.
