Well, I dusted off the assembly dust on my brain (PIC18F46K22_STALL.pbp.txt) (I think) and converted to pbp. The display is still blank and off, but the internal switches work so I think I have it connected correctly. Using a PIC18F46K22 since the logic level for the display is ~3.3V. Assembly to PBP3 initialization code attached. Anybody got some ideas of what to try next?
