Example Program: VertWheelRotation.bs2
This program displays your board's angle of rotation as shown in Figure 3-20 at the
beginning of this activity, page 92.
The General Case
The angle of rotation (θ) is the inverse tangent or arctangent of the component of gravity
acting on the Memsic 2125’s Y sensing (A
the X sensing axis (A
rotates both sensing axes by θ. By applying a couple of geometry identities, θ is also inside
the two triangles that show the components of gravity acting on each of the accelerometers
sensing axes (x
