interfacing between bipolar stepper driver and arduino without using PWM output

[Arun_Mali]

Hello, All

I want to interface my stepper Drive to Arduino duemilanove board speed variation is from external POT i want Pulse train output.

STEPPER DRIVE HAVING PULSE+, PULSE- AND DIR+ AND DIR- INPUT

my stepper motor need 2.8Amp. current with microstepping 1600 or 3200 settings can be managed on my drive.

HOW TO CONNECT THE STEPPER DRIVE TO ARDUINO, I CANNOT CHANGE MY STEPPER DRIVE.

Please suggest how to do it.

Stepper motors do not need to be connected to a PWM pin or to any special pin.

You need to post a link to the datasheet for your stepper driver - I cannot guess which one you are using.

Likewise, post a link to the datasheet for your stepper motor.

also look up the AccelStepper library
