Hello I'm using GY-80(ADXL345, L3G4200D, HMC5883L) module in my project. I have some queries for setting offsets. As the case in accelerometer when the device is kept stand still on a flat surface ,ideally it should read X : 0, Y : 0, Z : 980. Similarly what are the values I should get for Gyroscope and Magnetometer. Are X : 0, Y : 0, Z : 0 for Gyroscope and Magnetometer. ??
