Hey Brach,
Thanks for the help.
I have NOT soldered the jumpers yet, because that step comes a little later in the instructions. Is that key? Should I do that BEFORE testing the other bits?
With the jumpers unsoldered, there is continuity through some of the pins on the micro controller to ground all the time, and when the tap is pressed those both still have continuity AND one other pin is
connected to ground.
I don’t know how the pins are numbered, so when viewing the schematic on page 11 of the instructions, the “always on” pins are on the top row, #7 from the left, and the bottom row, #8 from the left. The tap footswitch, when pressed, grounds the 4th pin from the left on the bottom row.
Hope this makes sense, please ask for any clarification that helps.
Thanks,
Tony
