Gammon Forum : Electronics : Microprocessors : ADC conversion on the Arduino (analogRead) (http://www.gammon.com.au/forum/?id=12779)
This the thread you were talking about Rx7man ?
yep :) The guy's a pretty smart feller.. and must have pored over the datasheets for a long time!
no doubt, I'm particularly interested in the section that unblocks adc reading
I'm going to have to look into that as well, it really piqued my interest as well.. I was thinking of starting the ADC read, then doing the smoothing on the previous variable I had read, then getting the next value
