PIC16F690 Comparator C1 - some helpage needed!

I disagree.
You seem to be doing fine.

Anyhow, I've been playing with the tone detector I mentioned in the other thread.
Getting some interesting results, but nothing workable yet.

If that's where you're headed with the comparator, I may have some thoughts ... although, not very good one's.

Thanks for the moral support!

re extracting frequency from an analogue using a comparator - well, as you know, I used a sig gen - it was good, I used a guitar...alas, as predicted the result were just too erratic. I'm not at the stage yet where I feel up to programming in sufficient 'intelligence' to cater for all the variations (averaging, disregarding counts outside a 'window etc'), but that's where I want to get to.

In the meantime, I've since changed to a PIC16F690 iiit's a challenging little PIC for someone at my level, but it has way more pins for me to play with (the last IC got on my nerves becuase I had to share some of the programming pins with the comparator pins - mucho switching back & forward)

I read that Application Note you linked me to in my other thread ....I'm still standing on the chair trying to catch the info that went way over my head!

Well I thought I would have something to say ... but I haven't got the darn thing working either.

Maybe I should go read that appnote again.
I'll use a butterfly net to catch the stuff wizzing over my head.

Haven't given up yet.
