annotate Discovery/Src/check_warning.c @ 331:b4c578caaafb I2C_Improvment
Added plausibility check for pressure values
In case of I2C communication problems at startup the dc jumped into dive mode with depth up to 300m. As no CRC is applied a bit flip may also occure during normal operation without detection => added a plausibility check if last measured value fits to the last measurements
