Anyone figured out how to read internal Vcc? #203

Closed ErikApption closed 2 years ago

ErikApption commented 2 years ago

I tried many Arduinos samples to read the internal voltage but I am not able to get any reading that makes sense, although the ADC is supposed to have a decent precision. None of the samples I've tried, both to get the Ref voltage or to read the internal Vcc worked. Any suggestions?

The fix in #130 would allow to select 4/5th VCC, which would allow to read that data. But currently the ADMUX can only select the first 8 inputs, not the extended ones. You may be able to merge it for yourself.
