    Wink no mod needed ...

    Hi, Sebastien

    IF you intend to use PBP ... I would recommend you to simply enable the HSPLL mode ( 4x Xtal frequ. ) ... in the Chip CONFIG lines.

    You just will have to declare 24 Mhz as a clock frequency ( DEFINE OSC 24 ) ...

    the only backdraw will be for " slow PWM " generation ... 1465 Hz will be a minimum ! and some little limitations with the Pulsin, RCTime ...not frequency compensated command.

    No need to modify your card, then ... if 6 Mhz is not in use for another chip on the card !!!

    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 " !!!

    Default Great, it explains a lot.

    I never heard about the HSPPL, this explains why this card is delivered with 6 mhz crystal the lower model got a 10, i did'nt understood why a much better pic got a lower crystal. Now I got it 24mhz is nice for that card.

    Merci beaucoup
