My still-new Picade PCB seems to have a shorted-out pin? Everything was working great but my “coin” button stopped working. I backtracked the problem to the PCB which even disconnected from the wiring harness is emitting a bunch of "c"s which corresponds to that button.
Did I fry a pin and if so, how? Is something else possibly wrong? It seems like there are sketches out there that I could use to repurpose the volume keys and ignore the input on this pin but dang, its a dissapointment.
