Hi there,
I'm trying to do the groundwork on using the comparator in the F876 but I can't seem to find the internal resistor values for the chip in the datasheet.
I'm probably missing something but I thought I could get some additional input from the forum as well.

I need a low or a high sig based on the input voltage to the comparator. The trigger voltage is going to be around 0.8vdc, maybe lower. Will I get more accurate results with an external vref as opposed to the internal vref?

What about the deadband of the internal comparator? Has anybody noticed a significant amount of chatter when the signal approaches the threshold v?

How do I set the threshold voltage(s) in PICBasic Pro?

Thanks

I found this in another search in case you were/are in the same spot as me but were afraid to ask.... ;-)
