about tuning process #3

I am currently working on a module, following your project exactly. I do not have any electronic knowledge, so I do not understand the tuning that you explained very well. If you are okay with it, could you please explain the tuning process in detail? Thank you.

honestly this was my second ever project and I never really followed through on the explanation. I will try to redo the whole thing soon and make it more usable but for your build ill try to find a solution. I'll get back to you next week

thank you for the answer :) I did tunning process on my own. Is this correct?

5v to 3.3v (scale down) Vin(5v) *(R21(33k)/R21(33k)+R19(18k) = Vout 5v:1 = Vout:a(AD_CH1_calb) (in my case AD_CH1_calb = 0.971)

3.3v to 5v(scale up) 5v/3.3v = 1.51515 0.51515 = 5k(adjustable)/6.8k set the 5k trim pot value( in my case around 3.5k)

When a cv in value reaches around 4.5v to 5v, cv out(quantized value) pops up the same high value. Is this normal? ( I didn't change any setting value)
