Thonny is telling me I need pullup resisters
I've tried 4.7k to 3v and 5v

  1. what voltage to pull it up to, 3v or 5v?
  2. what resistance?
2
  1. to the voltage of the chip, so to 3.3v in case of rp2040
  2. Something between 1.5K -10K

I tried 4.7k at 3v, nuthin. Still telling me i need pullups, let me go down to 1.5
Tnx

maybe it's better to ask on the python forum

Im also there. Discovered that if use the adafruit .uf2 theres no pullup message

Then ... i coded it in micropython and got it working. Which brings up other problems down the line ... LOL
