I have connected a 10k lin pot, via a 4067 16 channel multiplexer.
Im powering my nano via the pc over usb.
I multiply the analog in by 20, just to get a good readout with decimals, to read pot reading stability
And at the extreme pot point (closed and slowly moving up from there), i get a pretty jumpy value between 0 and 2,5. Other pot locations seem pretty solid. It only seems to be the low end values of the pot that are exteremly jumpy.
Could this be a psu thing? Or maybe i need to solder in a cap somewhere between each pot output connection to the multiplexer?
I can do filtering in XOD, in the sense that i could apply low pass filtering, but my logic tells me that this wont fix the 0-2,5 problem, only small jittery things (which is also needed).
How would i go about solving jitter? something like a slew limiter/portamento/lag processor/low pass filter is needed, but there doesnt seem to be anything like that available. How would i go about making one in xod?
I am a noob:)
