diff Small_CPU/Src/pressure.c @ 688:8c92f7743e14 Betatest
Added sanity check for temperature and pressure values:
It happens from time to time at the debug hardware (electronic without housing) that pressure or temperature are in an invalid range . To avoid side effects a sanity check has been added.
