I don't think it is a calibration issue. I connected it to a rpi3 with an openplotter image that i dowloaded yesterday. First i had the same problems there. Than I added two pull ups of 3k3 on the i2c lines, and it all became stable.
Sadly enough not for the rpi zero.. that remained unstable.
So I continued testing on the rpi3 which went well untill 5 minutes ago, than it became unstable again. After rebooting it was stable again.
Do the i2c interfaces use different speeds on the two devices? Can I switch it to a lower speed?
