This is what I did to make it work for me...
All my microcontrollers out of the bag were on "loco 3"--that is when I used the
remote, all 3 motors worked when I used the C up/down and 3 button for the
light.
So putting one motor on the track at a time, I went to Loco, selected 1, then
changed the value to 1. then I went into physical CV1 and also set it to 1.
Under phys you can 'dump' the info to the microcontroller by pressing P3. In
Loco you can't commit the data to the microcontroller--that is what was screwing
me up for a while.
Anyway, then I put the 2nd motor and followed the same procedure, but used loco
2 and CV1 = 2
and 3 was loco 3 and CV1 = 3. After committing data to the microcontroller via
pressing P3 under Phys, it took. Now all motors are on their own channel.
I may go pick up another microcontoller and do my last LEGO motor, but we'll
see--3 on my layout is a little much as it is :)
But I'm sold. It works wonderfully. I *may* try to get a help doc together for
ya (if I have time b/w work and NMRA and rtl15 and .... well, life in general...
:) )
Playing more though. I'll keep you posted.
