Re: How can I reduce ADC drift
I did an extra test to confirm it wasn't another component on my main test board that was "messing up" the power.
I powered my isolated PIC with that DC-DC converter and sure enough ADC was jumping between 546 and 569 using my pot.
So now i have to find a 7805 variant that can supply 700mA without breaking a sweat.
My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!
