Hi All,

I am trying to figure out the math being performed in the Cordic Object by Beau Schwabe

In the object for the H48C Tri-Axis accelerometer Beau uses the Cordic calculations

to calculate ThetaA,B,C from the g-forces on the X-Y-Z axis.

This is the address for the object http://obex.parallax.com/objects/178/

I am trying to figure out what is the math being used .....

1- What does the Cordic object do?

2- How is the ThetaA/B/C being calculated from the z/x/y g-force readings? What

are the math formulas?

Can anyone please point me to the right place for the formulas?

Cheers
