I got a ADIS16480 and I am able to read and write to all readable/writable registers on all pages.
I can reed and convert all sensors measurements without problems (accelerometer/magnetometer/rate gyro/pression and temperature).
When it comes to the EKF outputs, i get 0 on all quaternion and angle registers.
Am i missing something?
Is there a register that has to be modified to startup the Kalman or it should start directly after powering up the device.
