/* Example sketch to control a stepper motor 
   with DRV8825/DRV4498 stepper motor driver, AccelStepper library 
   and Arduino: acceleration and deceleration.

#include "AccelStepper.h"



// Define stepper motor connections and motor interface type. Motor interface type must be set to 1 when using a driver:

#define dirPin 1
#define stepPin 2
#define motorInterfaceType 1

// Create a new instance of the AccelStepper class:
AccelStepper stepper = AccelStepper(motorInterfaceType, stepPin, dirPin);

void setup() {

  // Set the maximum speed and acceleration(for Halfstepp ca. 70/min) :
  stepper.setMaxSpeed(470);
  stepper.setAcceleration(400);
}

void loop() {
  // Set the target position (8 Revolutions for and Back):
  stepper.moveTo(3200);
  // Run to target position with set speed and acceleration/deceleration:
  stepper.runToPosition();

  delay(300);

  // Move back to zero:
  stepper.moveTo(0);
  stepper.runToPosition();

  delay(300);
