Just finished by build and got to the point of Calibration & Setup step 3A (plugging it in) to find that the btpass switch is only working as a momentary switch, it doesn’t “latch”. I know the switch itself is momentary, but my understanding is that the microcontroller is programmed to toggle the bypass on and off. The red bypass LED only stays on while the switch is momentarily depressed, and during that time I get no sound through the output. Troubleshooting suggestions? Thanks!
Make sure that pin 11 on the microcontroller is being low (close to 0 volts) when the bypass mode is enabled. Also make sure that when momentary mode is enabled pin 11 goes high (close to 5 volts). Test this and let me know what you find.
Allow me to interject with a clarification. I believe my partner is referring here here to the toggle y labeled MOM / TOG. This toggle switch toggles the foot switch between Momentary and Toggle modes.
