But in this case we need an data type for accumulated rotations
(unimportand if the driver or device do this).
I whould recommend:
Extending the IMUSensor for invalidatation of axis and sensors.
Extending the IMUSensor for Accumulated Gyro values to make the handling
better and be on the safe site and let the modules later on do the
differentiation.
But the mode (non-differential or accumulated) should be handled by the
Driver.
In accumulated mode the Driver could do the differentiation and
vise-versa for rad/s mode to set the members in the new IMUSensors module?!.
