Hi @Hicss.2033 , it is normal to get values different from 000h. If you consider the L3GD20 gyro (the sensor mounted on that discovery board), which is btw an old part number, the zero rate level is:
while the sensitivity is 8.75mdps/LSB in case of FS +-200dps.
So the ouptut gyro can be a value between +-477h (decimal -+10/0.00845 LSB). Is this your case?

Sorry for the late replay, but when I'm rotating the board, does the digital zero rate level must be considered to get the speed of rotation of the board (for example the speed of rotation is the measured value +- the digital zero rate level)? Is there some technique that I must adopt to get such measure or some technical notes that explain how to get such measure? thanks for yor answer.

Also I see that there is drift whenutilizing the gyroscope. Is it possible to eliminate such drift?
