Hi folks!

Having got myself a step motor from an old
printer, I have identified that it has 2 split
coils and now I need to know the sequence in which
the coils need to be energized to rotate the
motors in one direction and in the other. Is there
a standard way of doing it?

I would be grateful if you can enlighten me on how
to do it.

I'm using a non-inverting driver (L293D) and a PIC
16C84.
