I am one step closer/ further away again.
I realized I had my AME8811 the wrong way around, so i fixed that, and now I have the same problem again! So now I know why I had the problem in the first place, what a coincidence.
If I bridge the AME8811 and have the attiny run at 5.5 volts, it works, however, if i run the attiny at 2.29 volts, it does not. So maybe I should run the mcu at 5.5 volts and have it take the power before the ame8811? how high can the mcu go voltagewise?
