D1 has changed to a 5V1 zener and is loading the circuit a little bit. Adjusted voltage based on tested value on prototype. This value may differ on production units so expect this to possibly change.
Reads continuity at a fixed ~100ohm or lower, and diodes with intelligent detection of LEDs vs normal diodes. Some values may need to be changed still.
ADC is sort of functioning, but not reliably. LEDs are sort of working. Buzzer isn't working right and is nearly always on as I can't set the PF2 mode.
