Steppers

Archiver

Would anybody Know where i could find some pbasic code for driving 2
stepper motors (robot style-opposed motors) using L297/L298 drivers.
Thanks in advance

There is not much to the code for a L287/298 setup. It is a step and
direction interface with an enable pin. Drive the enable high (or tie it
high) and then sent a pulse every time you want to step and toggle the
direction line before the pulse if you want it to go the other
direction.

Hi. Im driving dual steppers using L297/L298 H/bridge & controller
circuits, each motor has its own circuit identical and interchangable
to the other).The stepper controller chip requires enable, direction,
and pulse signals for speed from the bs2. One of my many problems is
that the motors are running at different speeds with the same
pulseout command (1000). After diagnosing, the variation looks to be
comming from the stamp. Have i stuffed something or missed something?
Any advice is much appreciated.

Thanks in advance
