Hi all,
I want to use the comparator pins on a 40x2 chip for reading adc10 voltages using an external precision voltage source for best accuracy.
The manual says the adcconfig Vref+ pin is A.3 and the Vref- pin is A.2, but in the picaxe pinouts section here http://www.picaxe.com/What-is-PICAXE/PICAXE-Pinouts/
it says that those pins are Comp2+ and Comp1+ respectively. Shouldn't they be Comp1+ and Comp1-? Also, looking at the pinouts page, what are the other A.0 and A.1 reference pins? How are they used, and are they used by another command?
