I just picked up a nice Sparkfun F1232 board and I intend to use it to monitor the power. My assumptions are that I can power it with a super cap (as backup), 120vac to 12vac to op amp (10:1) and measure that with the ADC (10b). I'll be using the 32k xtal and the usart at 9600. I'll also be counting the frequency. Does anyone have any example adc circuits? I've been having trouble finding anything on the ADC with veref.
