I,ve some problems with calibrating.
I can't see the wave with the specified settings. Is there a more detailed tutorial.
I followed the trouble shooting guide.
I checked resistance of the knob:
Pin 1 to 3v3 has 10K
Pin 3 to 3v3 has 10K
Pin 4 to 3v3 has also 10 K
But the knob only works if i push it.
Voltage on the analog board is also okay.

Re: Problem with calibrating
Hello Sidey,
And the resistance from ground (batt-) to pin 2&5? Must be 0 ohm.
It looks like the ground pin of the Rotary PCB does not make very well contact, becouse you say it works when you press on it.
The track of both PCB's has a large copper area, so you have to solder it long enough to make good contact.
Hope this helps.
