I may even have the loopback adapter, but that only tests the parport. I need to exercise the BoB itself, send something to pin one, and find it with a scope probe, repeat for pin 2 etc etc. Ditto for the inputs. They are there, but NDI what pin they are by the time it gets to the 5i25. Or from the 5i25 to the edge connectors on this board.
I suppose I could hack up a hal file that only loaded one encoder, so the rest was all gpio, and set up a couple tones, one inverted so I could tell which pin was which and go thru that one "axis" at a time. But that would make me think, and keep copious notes too. I'll see what I can do though. Thanks Peter.
