Hello! I have a few questions, that are probably the result of overthinking...or perhaps underthinking.
I have a free running ADC using a prescaler of 16.
I read in the ATmega328 and ATtiny85 datasheets sections on the ADC that "when auto triggering is used, the prescaler is reset when the trigger event occurs."
Later it says "free running mode will not cause a trigger event."
There are a few things here I'm not sure I understand.
If free running mode doesn't cause a trigger event this would mean that the prescaler doesn't reset in free running mode, right?
Does "prescaler reset" mean what I think it does? I'm interpreting it to mean that it resets to the default 128. If it does, does this mean the prescaler would have to be set after each read?
