AccelStepperSpark (community library)

Summary

A library that allows you to control stepper motors with an object-oriented interface. It works with 2, 3 or 4 pin stepper motors.

AccelStepper for Particle

This is the Arduino port of AccelStepper library for Particle devices. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors.

The standard Arduino IDE includes the Stepper library (http://arduino.cc/en/Reference/Stepper) for stepper motors. It is perfectly adequate for simple, single motor applications.

AccelStepper significantly improves on the standard Arduino Stepper library in several ways:

• Supports acceleration and deceleration
• Supports multiple simultaneous steppers, with independent concurrent stepping on each stepper
• API functions never delay() or block
• Supports 2, 3 and 4 wire steppers, plus 3 and 4 wire half steppers.
• Supports alternate stepping functions to enable support of AFMotor (https://github.com/adafruit/Adafruit-Motor-Shield-library)
• Supports stepper drivers such as the Sparkfun EasyDriver (based on 3967 driver chip)
• Very slow speeds are supported
• Extensive API
• Subclass support

Example usage

#include "AccelStepperSpark.h"

// Define a stepper and the pins it will use
AccelStepper stepper; // Defaults to AccelStepper::FULL4WIRE (4 pins) on D2, D3, D4, D5

void setup()
{
// Change these to suit your stepper if you want
stepper.setMaxSpeed(100);
stepper.setAcceleration(20);
stepper.moveTo(500);
}

void loop()
{
// If at the end of travel go to the other end
if (stepper.distanceToGo() == 0)
stepper.moveTo(-stepper.currentPosition());

stepper.run();
}
