Automated reboot?

I assume your responding to me. The issue with the oled is not bus related, it fully works except brightness pulsates. Feels more like a capacitor misbehaving but no time to debug now.

And yes go for 3.3v as I already said. Everything is working with the tweaks I described in the other topic.

I meant to respond to @Marco . His other post was about OLED display freeze.
