MPU6000: Problem with AFS_SEL

By d4johnprotonmailcom , 19 January 2022

Dear sir/madam,
I have an MPU6000 sensor which I use to measure acceleration in three axes. In the datasheet and the register map files of the sensor, two sensitivity scale factors are defined for gyroscope and accelerometer separately.
When I change the sensitivity scale factor of the gyroscope which is FS_SEL, I see the scale and the maximum measured ratio of the gyroscope change.
However, when I change the sensitivity scale factor of the accelerometer which is AFS_SEL, the measured acceleration is always about 16384 that is 1g for +/-2g measurements. It seems that the AFS_SEL doesn't change. The address of the register that I try to write to is 1C. Is this the correct address?
Could you please help me with this issue?
Best regards,
David
