Hello,
I am having the same problem as the OP I can’t find the open source code anywhere. I have the hex but there is no source code in the download package. Please advise
Update: I shined light around Opto-1 when there was no power to the pedal and I got a change in resistance when probing TP1 and 2. So, I reheated the heat shrink and used tweezers to clamp down on the shrink and was able to seal it enough so that when there is no power to the pedal and I probe TP1 and 2 I get an open reading. I also re-flowed Q1 and tested R8 and R7. R8 and R7 are the correct values and both have 4.98v. I also tested the trim pot and it seems to be operating correctly. Next I am going to measure the resistance between R15 (the pin of R15 closest to pin 1 of U2) and pin 3 on U2, with the power off and the voltages on the pins of U2A, pins 1,2, and 3.
Thanks for your time and attention.
