Hey Darrel,
Disabling TMR1 after the event has zero affect on the value that CCPR1l & CCPR1H record at the time of the event. The value in Timer1 is captured immediatley on event.
Can you recommend something for the OP that wiil fix it?
If you can -- he gets the free PIC, and I'll send you a six-pack of your favorite BEER...
FYI: Disabling the timer after the capture event has zero effect on the value captured by the hardware catpure module.
Remember ... It's done in hardware

Ship a couple of the chips tomorrow. I will pay for them. I need to get this calculating correctly soon. If you mail tomorrow I bet I have it saturday.

Hey Toby,
I'm real sorry I didn't order three of these things for you, but if you refer back to post
#23 -- you'll see what happened.

Cool, but you have to prove me wrong to get that BEER...But long before he gets them, the problem will be solved, and I will drink your beer.
What's your favorite suds?
Just want to be prepared for when you DO....

One will be fine too, will it ship tomorrow? Not that I don't have faith in DT

Tobias,
Not that I think there is anything wrong with the way you are doing things, but - I earlier posted a routine that can read virtually any number of tachometers to good accuracy, and to RPMs far past 15000 (if your tach output is the standard 2 pulse/rev) type. It averages over a period, so jitter
isn't a problem.
It is interrupt-driven, and runs totally in the background.

Did you ever test it on an 18F4620? I found it. I am sure I will have a few questions in the morning.

Yep. My order was shipped UPS RED, and should be here tomorrow, so I'll be shooting
your 18F4431 TQFP out by standard Priority Mail. You should be receiving it pretty fast
with you being just down-the-road.
You should .. he's a real genius at this stuff...Not that I don't have faith in DT
BTW: Your total for the 18F4431 TQFP + shipping is $11.55, which is exactly our cost for
the part + shipping. Just make a Paypal payment in this amount to [email protected]
And, if you need any help using this thing - just ask. I've done a boat-load of commercial
apps with these.

Thanks check your PayPal acct

That is just so WRONG ... hit squad has been mobilized....BEER thief

Absolutely true!
But the numbers given originally were from multiple captures without the timer being turned off. So they were irrelevant and confusing.
I can ... soon. Just don't want to have to say Oi Vey again.Can you recommend something for the OP that will fix it?

Hell, ship him the chips, and I'll pay for them if I fail.
But long before he gets them, the problem will be solved, and I will drink your beer.
