Okay! D4 is low and I don't know why. I traced it back to the mcu just fine and doesn't appear shorted either.?
I haven't connected anything to it, have only connected the FB and I looked I the code and it is initialized to pull up...
If I pull the pin high externally, the screen (only) shows "7.125 USB" and nothing works.?
I'm going to verify that I have a working D4 and if not, assign SPOT to a different pin.
That's my best guess for now ! aa2mz
