control DC motor via labview and L298N(+arduino)

[little flower]

Hello!

I want to control DC motor via labview and L298N(+arduino)

It  just performance  stop and counter clockwise run  and clockwise run

But I just find  servo motor and step  motor example for labview

And a example on labview.

If I want to modify the models vi.

What can I do?

Do I have to reprograming arduino?

Thanks very much.

these arduino program

int E1 = 5;
int M1 = 4;
int E2 = 6;
int M2 = 7;

void setup()
{
pinMode(M1, OUTPUT);
pinMode(M2, OUTPUT);
}

void loop()
{
int value;
for(value = 0 ; value <= 255; value+=5)
{
digitalWrite(M1,HIGH);
digitalWrite(M2, HIGH);
analogWrite(E1, value); 
analogWrite(E2, value); 
delay(30);
}
}

There is DC motor in it.

I use arduino UNO and L298N to contol

L298N information on add

Picture is UNO and L298N + Mechanic

Thanks very much.

This is arduino program.

Sample Code:

// motor A

int dir1PinA = 13;

int dir2PinA = 12;

int speedPinA = 10;

// motor B

// motor A

int dir1PinB = 11;

int dir2PinB = 8;

int speedPinB = 9;

unsigned long time;

int speed;

int dir;

void setup() {

  pinMode(dir1PinA, OUTPUT);

  pinMode(dir2PinA, OUTPUT);

  pinMode(speedPinA, OUTPUT);

  pinMode(dir1PinB, OUTPUT);

  pinMode(dir2PinB, OUTPUT);

  pinMode(speedPinB, OUTPUT);

  time = millis();

  speed = 0;

  dir = 1;

}

void loop() {

  analogWrite(speedPinA, speed);

  analogWrite(speedPinB, 255 - speed);

  // set direction

  if (1 == dir) {

    digitalWrite(dir1PinA, LOW);

    digitalWrite(dir2PinA, HIGH);

    digitalWrite(dir1PinB, HIGH);

    digitalWrite(dir2PinB, LOW);

  } else {

    digitalWrite(dir1PinA, HIGH);

    digitalWrite(dir2PinA, LOW);

    digitalWrite(dir1PinB, LOW);

    digitalWrite(dir2PinB, HIGH);

  }

  if (millis() - time > 5000)  {

    time = millis();

    speed += 20;

    if (speed > 255) {

      speed = 0;

    }

    if (1 == dir) {

      dir = 0;

    } else {

      dir =1;

    }

  }

}

Sorry I forgot saying.

My motor is DC stepper motor !

Hi little flower,

Sorry to inform you that the arduino hardware is not generally supported on the standard NI discussion Forums. However, if you go to www.ni.com/arduino and click on the “Discussions” tab under the “LabVIEW Interface for Arduino” header, you will be able to post your question there. Hopefully someone will be able to assist you from there.

Best,
