    Thank you Tracy,

    Your idea is the good idea !

    Temp_Haut (and Temp_bas) must be variables order constantes. All is ok now !


    Thank you

    You really need to read the datasheet for the DS1621. The limit registers use the same units as the other temperature registers. The top of page 4 of the datasheet shows how the temperature is represented and gives some examples.

    Thanks. I read page 4 and now I know to use 7D00h for 125 degrees.
