    Hi, Karen

    AS the DS18x20 has a +/- .5 degrees precision ... is it useful to show the tenths of degree ???

    Now, take the DS 1820 Datasheet ... How much degrees for 1 Count ???

    Are you able to show the 1/10 degree ???

    ( Check if your DS 1820 is a DS1820 , a DS18B20, a DS 18S20 ??? )

    Take the DS 18B20 Datasheet ... How much degrees for 1 Count ??? Can you read .1 degree NOW ???


    NOW, for 2 DS 1820 ... Two solutions :

    1) each has its DATA PIN
    2) you have to address them by using their DEV i.d. before sending them commands ...

    Make your choice ...

    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 " !!!

    Thanks ,
    but I've never programmed anything before and have only heard of stamp not used it.
    I'm just teaching myself by trial and error as I go along.
    hmm I can see some research coming up on how to address each device by device ID and how I find the device id to start with!
