I had a couple little problems with my testing.
I first made a little test board with a motor, speaker, and LED's for all the function outputs. You can connect the BLU-2200 to the test set with screw terminals for all 13 leads. I figure this has to come in handy.
First off, the engine starts up as soon as power is applied, I couldn't figure any way to make it stop doing that. I wondered if that was a function of it being the only engine that is found.
Next, though I can't believe this doesn't work, I can't get either plain diesel lighting working properly, directional lighting never seemed to work. Also, I couldn't figure out how to get Rule-17 lighting to work, though maybe that's connected to getting plain diesel directional lighting working. I'm guessing I just haven't stumbled on the correct sequence of options to make this work. Of course, this being a beta app, maybe it's the app that is causing some of the issues.
It is pretty impressive that tiny board has all that functionality, I have to grudgingly admit!
