'PIC and controlling a stepper motor'

Friends,
I looked at piclist.com but the search did not come up
with any answers. I also looked at the archive at Iversoft
but my search did nothing as well. What I need to do is control
a bi-polar stepper motor, fwd and rvs. Does anybody know of
information (tutorial, code examples,...etc) or has any
info that would be willing to share with me. I will
be using the ST ( and ALLEGRO) 6219 stepper motor driver
with a PIC16F874-20/P.
Any help/advice would be greatly appreciated.
Thanks alot!!
Best regards,
Steve

YIKES! That only HALF steps. How crude.
Currently (pun intended) I am implementing
microstepping using a pair of Allegro 3955
chips. MUCH better....simple too. Try them,
you'll like them.

Oops that went out too fast.
The Allegro Product Description explains,
in painful detail, the various stepping
modes. For stepping and the 3955 all you
have to do is implement the tables shown
in the document.
I've also done this with a 16C65 to microstep
using high voltage, pass transistors and a
hefty resistor (NO Allegro parts.) But that
was inefficient.
It is also described, I believe, in some App Notes
at the MChip site.
