I want to control DC stepper motor via labview and (EasyDriver V4.4 or L298N) + arduino
It just performance stop and counter clockwise run and clockwise run
But I just find servo motor and step motor example vi in labview
If I want to modify the models vi or use 3Dmicro Toolkit.
What can I do?
Do I have reprograming for arduino ?
My Attachments picture 1.2 is my method.
2 and 3 are labview program vi.
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);
}
}
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;
}
}
}
