Re: [CAD_CAM_EDM_DRO] as simple as 1,2,3...

Jack,

You could:

1. Connect A & B phases to Joystick's sw 1 and 2.

2. Use a short program to read sw bits.

3. Write program to Count the "steps" (walk through all 4 state
transitions of A & B).

4. Run program, start at known shaft position, turn slowly until 1
complete revolution. Or do N revolutions, and divide result by N.

5. (extra credit) Connect the index to 2nd joystick switch 1, and an
edge of it's signal to "gate" one full (or N full) revolutions of the
shaft.


Alan (just did that)
