cann't work a stepper motor with labview, arduino and easy drive 4.4

[kobied]

Hello

I'm new to labview and arduino, I have installed all the needed software and hardware need to run labview and arduino uno.

I have an easy drive 4.4, stepper motor and power supply.

I have done all the arduino learn kit cirects using labview and all worked OK, so I think have all the needed software and hardware correctly.

when i try to operate a stepper motor using the labview example (the one which comes with the LVIFA) nothing happens, i tested the motor and the hardware using the arduino example code and the motor work.

can someone help me i'm quite desperate.

arduino code:

int Distance = 0; // Record the number of steps we've taken

void setup() {                

pinMode(8, OUTPUT); 

pinMode(9, OUTPUT);

digitalWrite(8, LOW);

digitalWrite(9, LOW);

}

void loop() {

digitalWrite(9, HIGH);

delayMicroseconds(100); 

digitalWrite(9, LOW); 

delayMicroseconds(100);

  Distance = Distance + 1;   // record this step

  // Check to see if we are at the end of our move

  if (Distance == 3600)

  {

    // We are! Reverse direction (invert DIR signal)

if (digitalRead(8) == LOW)

    {

digitalWrite(8, HIGH);

    }

    else

    {

digitalWrite(8, LOW);

    }

    // Reset our distance back to zero since we're

    // starting a new move

    Distance = 0;

    // Now pause for half a second

    delay(500);

  }

}

thank.
