    BMP388 Temperature Measurement Range

    BMP388 Temperature Measurement Range

    Hi:

    I am trying to use the BMP388 for basic weather info.  I am using the forced mode for starting measurements and get a 16-bit result as expected.  But what is the temp measurement range so I can scale to a meaningful number?  At this point I am not concerned with high accuracy, I just want to get ballpark numbers then go from there.  I am using a PIC mpu so my program area is very limited and will have to avoid all the floating point libraries.

    Thanks!

    The specifications are incomplete: the datasheet reports some formulas (and yes there is a bit more info to reverse engineer from in the reference code) but i expect a datasheet to report the exact range of the pressure, temperature and timestamp raw binary values.

    Also the datasheet says the timestamp is 24 bits in the text, but there are 4 8-bit registers in the map.  what are the units?

    Could someone from Bosch please give a formal definition of the register values OR of the outcome of the computations in appendix 9  p55 of the BMP388 data sheet?
