Someone in the forums mentioned 2.56V, but i couldn't find it on the datasheet plus from measurements i'm more close to 2V. Can please someone point to somewhere?
Thanks!
Hi,
From the ATmega32U4 datasheet, section 24.5.2 ADC Voltage Reference, page 299:
The reference voltage for the ADC (VREF) indicates the conversion range for the ADC. Single
ended channels that exceed VREF will result in codes close to 0x3FF. VREF can be selected as
either AVCC, internal 2.56V reference, or external AREF pin.

Yes, it is. I've verified it now. Thanks
