This code uses speed calculations as described in "Generate stepper-motor speed profiles in real time" by David Austin or or with the exception that AccelStepper uses steps per second rather than radians per second (because we dont know the step angle of the motor) An initial step interval is calculated for the first step, based on the desired acceleration On subsequent steps, shorter step intervals are calculated based on the previous step until max speed is achieved.
Install in the usual way: unzip the distribution zip file to the libraries sub-folder of your sketchbook. Tested on Teensy including Teensy 3.1 built using Arduino IDE 1.0.5 with teensyduino addon 1.18 and later. Before asking a question or reporting a bug, please readīeginners to C++ and stepper motors in general may find this helpful: Do not contact the author directly, unless it is to discuss commercial licensing.

The latest version of this documentation can be downloaded from The version of the package that this documentation refers to can be downloaded from Įxample Arduino programs are included to show the main modes of use. Supports stepper drivers such as the Sparkfun EasyDriver (based on 3967 driver chip).Supports alternate stepping functions to enable support of AFMotor ( ).Supports 2, 3 and 4 wire steppers, plus 3 and 4 wire half steppers.
Most API functions never delay() or block (unless otherwise stated).Supports multiple simultaneous steppers, with independent concurrent stepping on each stepper.
It is perfectly adequate for simple, single motor applications.ĪccelStepper significantly improves on the standard Arduino Stepper library in several ways: The standard Arduino IDE includes the Stepper library ( ) for stepper motors. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors and motor drivers. This is the Arduino AccelStepper library.
