    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.

    But long before he gets them, the problem will be solved, and I will drink your beer.

    Just want to be prepared for when you DO....

    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.

    Not that I don't have faith in DT
    You should .. he's a real genius at this stuff...

    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.

    If Charles hadn't done it with DT_INTS, I might have been upset (longer).

    But he did ...
    More things to simulate.

    I might have to send Charles a 6-pack too.
