Re: [AVR-Chat] Why use the ADC pre-scalar bits

Thanks for the quick responses!  I guess the next question is how
much accuracy do I lose?  For example, what kind of variation could
I expect with an 8 MHz clock and a prescale of 2?  I have the results
left justified and am only interested in 8 bit readings but want a 
high sample rate.
