    Hi,

    I have two problems I think:

    1.  When I try to read the temperature and the pressure from the bmp 180 I am getting the same results no matter where I place the sensor, whether in a hot or cool place.

    The temperature is 82.7 C always and the Pressure is -43816.71

     

    2. The gyro X reading is -ve and keeps falling! Gyro Y reading is climbing.

    I am using sample code provided.

    I am using Pi Zero W with latest software.

    Can you offer any suggestions or advice on how I can fix this problem.

     

    Best regards,

    The sensor on the BerryGPS-IMU is the BMP280.  I have just updated the GIT repo with code which can be used;

    Regarding Gyro values changing, this is from noise and all gyroscope exhibit this behavior. This is why the values from the accelerometer and gyroscope need to be fused.  See this guide;
