Gday all
Is it possible to put a 12F675 to sleep and then wake it up when the value on an analogue input changes ( either up or down from the setting when the pic was put to sleep ).
I am controlling the speed and direction of a DC motor from a single pot, using the ADC to tell me speed and direction. When the pot is centered, the motor stops, and as such i cant use the comparator interrupt functions as i dont know which way the user will turn the pot. I know i can do it with external circuitry ( or with two comparators ) but was wondering if there is some sneaky interrupt settings i could use to do this in the 12F675.
ps Mel i'm now up to speed on 12F675 comparators, after my last little exercise, but cant see a way to do it.
