Using VREF pins for pots that don't reach ADC=0 or 255

[Demon]

I've removed all caps, and this pot works perfect. The TPS56637 circuit is that clean when it comes to noise.

WPU was fighting with the ADCin pin, trying to pull it up.

Now the slider pots might still be a problem; I'll test those later. But right now I'm putting back the 2nd pot with switch.




I'll probably put several of those caps back on, I'll see (like at ADCin pin).

Unfreakingreal... :bangheadinwall:


EDIT: Oh yeah, definitely had to put the caps back on. The 2nd ADCin started affecting the 1st.

I put all the caps back in, everything is stable.
