This code generates a circular interpolation motion profile as intended for a home-brew CNC machine. (CNC Codes G02 & G03)
I use Bresenham's algorithm calculates X & Y steps to accurately approximate a circular path.
The code will calculate arcs starting and ending in any quadrant.
I have not implemented a controlling feed rate so it is just a starting point.
