Hi,

I want to use a comparator in an F628 in mode 6 with comparator outputs
available off-chip. I intend to use the usual resistor network to add
hysteresis to the comparator and use it as a schmitt trigger.

Has anyone done this?

Any problems in using the on-chip comparators in this mode?

Will the PIC I/O on the comparator affect the calculations for hysteresis?

Regards

Andrew Crosland
