RuaAD I answer here, dont pm about this, talk in here. There are no embarrassing questions about this. As long as you dont have the full picture it looks hard, then its not.
No the battery is not used and the pin 29 is now used, I just did not edit the code. Wait for W11ce to remove the trigger MCPs and post the new code.
I tried the MCPs free floating on cables, on a board and directly on the PCB. The best method is directly on the PCB as W11ce did. All 6 are on the board then ( minus the two trigger MCPs).
