The system variable rotationX always contains the rotation of the device along the x axis. If the sketch angleMode() is set to DEGREES, the value will be -180 to 180. If it is set to RADIANS, the value will be -PI to PI.
Note: The order the rotations are called is important, ie. if used together, it must be called in the order Z-X-Y or there might be unexpected behaviour.
