Configurable Stepper Controller
I've always hated swapping stepper wires all the time, I can never get it right twice in a row; I've let the PIC choose the order instead. Of the 24 possible combinations of wires, 19 are reflections or rotations of other sequences, boiling down to 5 unique orderings if I've worked this out right.
The rightmost switch enables half-stepping, and the leftmost activated switch tells it to use sequence 5/5.
