    hello I don't know if it is the right place to put my question ! because I have quite the same need
    I must divide a signal (10 Mhz) to 10 Khz (OCXO asservissement with a GPS)
    I have an example in language "C" and I understand quite nothing !!! it use a 12F675 (clock is the 10 mhz signal)
    Hope somebody can help me, I think that I have to write in ASM language, not in Basic
    ASM is not easy for me ...
    so if somebody knows how to divide a 10 Mhz signal to get a 10 Khz output signal
    I would appreciate
    thanks

    First recommendation is to start you own thread to ask your question (instead of reviving a 14 year old one).

    Second, could you post the C code? Please use [ CODE ] and [ /CODE ] (without the spaces around the brackets). There are several of us that can decipher C. That might be quicker than starting from scratch.

    certainly the answer is " RTFM " or " RTFDataSheet " !!!
