My embedded application is communicating correclty with the MPL5115A2 on board. I want to add reading of delta values of altitude, but I obtain the same values of data out (i.e. the absolute altitude). Sensor is initialized as altimeter, 8 oversampling.
To read values I read 10 bytes from the sensor, starting from address 0, but registers OUT_P_DELTA_MSB and OUT_P_DELTA_CSB contain the same values of OUT_P_MSB and OUT_P_CSB. In order to read delta values should I set a different configuration? Shouldn't I just read adifference from the previously read values of altitude?
