Hi, I have a problem with my stepper motor 17HS4401, I connected it with DVR8825( driver)
I set vref to 1.2v and i upload this code
/* stepper motor control code for DRV8825
*
*/
// define pin used
const int stepPin = 9;
const int dirPin = 8;
void setup() {
// set the two pins as outputs
pinMode(stepPin,OUTPUT);
pinMode(dirPin,OUTPUT);
}
void loop() {
digitalWrite(dirPin,HIGH); //Enables the motor to move in a perticular direction
// for one full rotation required 200 pulses
for(int x = 0; x < 200; x++){
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(1000); // delay for one second
digitalWrite(dirPin,HIGH); //Enables the motor to move in a opposite direction
// for three full rotation required 600 pulses
for(int x = 0; x < 600; x++){
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(1000); // delay for one second
}
The motor should turn in the two directions, but it turns just in one direction.
