Hi
1) In the Atmega 1281 datasheet, ADC section, is says that when we change the
ADC reference voltage the first conversion could not be correct and recomend
reading twice.
In the ADC implementation for T2 there is a reference to a function called
"isPrecise" that seems to deal with this.
My question is: when I'm using diverse channels with diverse references the
driver automaticaly reads twice is it detects the reference changed? I think so,
but I would like to know for sure.
2) There is any reason (ex. compatibility with 128) for not defining the 1.1
voltage reference in the header file for the ADC (on the chips/atm1281/adc
folder)?
That bit combination is defined as reserved in that file.
Best regards,
André Rodrigues
