    DPS422 reference value for raw temperature and pressure measurement

    I'm using the DPS422 via i2C but not getting the correct temperature und pressure.
    Maybe I'm calculating wrong, but I can't find anything wrong in my code.
    Are there any reference values for the raw data that is send from the sensor?
    My raw pressure value is 0xFDDCE6 and the temperature value is 0x016932.
    The reason I'm asking is, because I think the pressure value is pretty high for room conditions.

    Thank you for your help.

    Hi Iudw

    I assume the reason your not getting any help is because calculation of the pressure depends on the settings you've made too. If you check the datasheet on page 16 (5.1.1) you see, that you have to apply Oversampling Rate kP.

    What settings are you using?

    Kind regards
