Cordic trig assembly code for PIC18f

[ScaleRobotics]

For instance

x = 25980
y = 15000

.....and that is 30 degrees

My perspective was all wrong in the above post. I was supposed to be lying down and facing East, that is the radian way.

to convert to degrees ......

Imagine a circle with degree headings, but instead of starting at the top, and going clockwise, as the numbers get higher, we are going to do something completely different. Starting at 90 degrees, we are going to go counterclockwise while our radians rise. From zero to 32,767 is the arc from 90 degrees (through 0) to 270 degrees. To complete the circle, our arc continues from 32,768 to 65,535 as it travels from 270 degrees to 90 degrees in a counter clockwise rotation.

So, as you can see there is just a little bit of manipulation to get the result in angle, but it really isn't too bad.

Thanks Joe.
