    Hi, Malc

    If your sensor gives ONE TIME the correct temp ...

    it is obvious ... you forgot to close the never-ending measuring Loop ... ( Mr de la Pallice )


    ....


    Did you modify the program ??? ( else than just config bits, Osc speed ... etc )


    -23tC 0.06 -28T

    This should tell your DS 1820 is in a freezer ...

    is it the truth ???

    I will do a test ( must solder a dedicated cable ) to see if I can have a delicious ice-cream ...


    the first line indicates : Bottom value of scale, actual temp, Top value of scale
    second line is scale and index showing where you are between Bottm value and Top value ...

    The "rocket" means the heating Output is ON ...

    Alain

    I give you the test results for negative temp ... keep on the line !

    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 " !!!
