It's hard to see what's going on from the picture. Can you explain what you mean by "in series?" they are supposed to be connected in parallel.

#

There's a diagram in https://faq.deej.rocks that shows how you can do the wiring

@neon fox Yeh, sorry. Its difficult to show all conections, but I made this diagram to explain better

Just realize I'm dumb, the pots are connected in parallel, still can't overcome the "parasitic" voltage from the other pots

#

Your schematics look good, this issue often happens in breadboards because they are basically dozens of little capacitors. What resistance are your pots?

#

My pots are 10k, but @plush vortex solve my issue recently. I have to connect my struf to 3.3v instead of 5v, that solve the issue

#

What board are you using?

rocky magnet Mar 24, 2024, 6:31 AM

#

rp2040-zero

neon fox Mar 24, 2024, 6:33 AM

#

And going to 3v3 let the pots go down to 0?

rocky magnet Mar 24, 2024, 6:33 AM

#

more less, still got jitter, but it much less than before

neon fox Mar 24, 2024, 6:34 AM

#

Well that sort of makes sense, glad you were able to fix this

rocky magnet Mar 24, 2024, 6:34 AM

#

Thx

@neon fox i covered this issue in this issue https://discord.com/channels/702940502038937667/1221272609422053437

#

basically shorting 5v to a part running on 3.3 when it is not a 5V tolerant part does bad things

rocky magnet Mar 24, 2024, 2:00 PM

#

I make it really smooth with no jitter with software. I uploaded the code to github!

plush vortex Mar 24, 2024, 2:00 PM

#

also, you have to know about your analog reference voltage,

#

what did you use for your filter?

#

i was going to add a IIR filter to my code

rocky magnet Mar 24, 2024, 2:01 PM

#

plush vortex what did you use for your filter?

Nothing, just software. I used a buffer

plush vortex Mar 24, 2024, 2:01 PM

#

that uses a 1/64 alpha value

#

you buffered then averaged?

rocky magnet Mar 24, 2024, 2:02 PM

#

plush vortex you buffered then averaged?

Yes, also use the full 12 resolution of my adc's to avoid dead zones

plush vortex Mar 24, 2024, 2:03 PM

#

not that we need to be efficient but an IIR filter works great for this sort of thing, It is what i use in my code for power tools on the speed potentiometer input

#

i also use shift functions to avoid multiply and divides

#

and it is also only 3 lines of code

#

and uses no additional memory

#

AccumulatorValue -= AccumulatorValue >> 6;
AccumulatorValue += NewAnalogValue;

and whenever you use the value

actualValue = AccumulatorValue >> 6;

rocky magnet Mar 24, 2024, 2:07 PM

#

Wow!! My code is really big at this point also make aesthethic changes for gui. I copy the idea from @hasty goblet but make it a little more efficient and adapt it for my display

plush vortex Mar 24, 2024, 2:07 PM

#

mine is really easy to move around stuff

#

and it is the same code really as the one you linked last night

#

effectively what that code does is average the last 64 readings

#

but we get 100 readings per second, so it really cushions the changes

rocky magnet Mar 24, 2024, 2:09 PM

#

Yeah, I saw it... still working on hardware to implement the layers.
Also, where do you get the icons.h? The look cool and would decluter the code

plush vortex Mar 24, 2024, 2:09 PM

#

i made them

#

but i didn't upload them separately

#

they will be on github shortly
