    Wink PIN 5 !!!! or controlled current ...

    Just play with voltage @ pin 5 ... see 555 Datasheet for that.

    Other ( read complicated for the use ...) thing to do is use the " constant current config" and drive this current with the PIC.

    Broadest freq range to be expected ...

    Hi, Darrel

    You're not right ... or right just for "classical" designs ...

    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 " !!!
