Supposing you build a barometer or altimeter ... using MS5534 or Hope HP03 ...
Hi, Martin
Assumingpressure will be read as i.e 1013.3 mb ( displayed number < 65536) ...
the difference between two measures will be < 32768 ... ( or you will feel really really really bad !!! )
sooo ...
the MSB of the difference will be 0 for positive difference and 1 for neg difference... add to that PBP offers the direct print of the value and sign : " SDEC Difference "

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 " !!!

The sensor is a Bosch BMP085. The actual raw un-compensated pressure value at about 260m (where I live) is -24200 in SDEC. I'm not sure what the range of values is going to be yet, I need to work that out yet (from sea level to say 1000m).Originally Posted by Acetronics

I'll try out the SDEC Difference to see what it does too.
