Just uploaded a video example of driving a stepper motor with ARC, and ez-bv4, and a dual H-bridge.

And to make it reverse direction would you set the PWM pins as a negative speed or set the 1-4 pins the opposite sequence?

Also if you wanted the motor to move plus or minus 45 degrees and stop how would you tell the script that?

Thanks

Well I'll do you one better and attach my stepper project file for you. The project includes scripts for Fullstepping in the clockwise & counter clockwise directions and Half stepping in the clockwise & counter clockwise directions.

Stepper.EZB

The degrees in which you would like to move depends on the steps/degrees that your particular stepper moves. Hypothetically, say it's 1 step per degree, then 45 steps would be 45 degrees. Here would be an example of 45 degrees of movement:

REPEAT($y, 0, 44, 1)
  $x = 10
 Set(D1, ON)
 Set(D3, OFF)
 Set(D2, OFF)
 Set(D4, ON)
 Sleep($x)
 Set(D1, OFF)
 Set(D3, OFF)
 Set(D2, ON)
 Set(D4, ON)
 Sleep($x)
 Set(D1, OFF)
 Set(D3, ON)
 Set(D2, ON)
 Set(D4, OFF)
 Sleep($x)
 Set(D1, ON)
 Set(D3, ON)
 Set(D2, OFF)
 Set(D4, OFF)
 Sleep($x)
ENDREPEAT

So this code sample will Repeat a fullstep sequence 45 times, here are what the values in the repeat loop represent:

0 = start value 44 = end value 1 = increment by 1

If the stepper seems to be skipping steps our moving backward at times you may have to change either the code or the stepper wires to be in the proper sequence or it might be moving too fast. If speed is the issue, just increase the $x value to slow the stepper down.

Thank you so much!
