    If you need high precision timing ... just do use external oscillators like those : https://www.mouser.fr/datasheet/2/96...HS-1665263.pdf

    just my two cents ...

    poor man will add a trimmer capacitor in the Xtal circuit, but to be trimmed for each chip ...

    Other cheap solution is to turn to a 16F88 or 87 ( pin compatible ) and play with the OSCTUNE register ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Lester has taken care of this and hopefully we do receive replies now.

    Please post to test others.

    Well I didn't receive a notification that this thread was replied to. I guess it's still not working.
