New option for user to set the min allowed pulse width. To purchase a commercial license, contact Revision History Version 1.0 Initial releaseġ.1 Added speed() function to get the current speed.ġ.2 Added runSpeedToPosition() submitted by Gunnar Arndt.ġ.3 Added support for stepper drivers (ie with Step and Direction inputs) with _pins = 1ġ.4 Added functional contructor to support AFMotor, contributed by Limor, with example sketches.ġ.5 Improvements contributed by Peter Mousley: Use of microsecond steps and other speed improvements to increase max stepping speed to about 4kHz. ![]() See Commercial Licensing This is the appropriate option if you are creating proprietary applications and you are not prepared to distribute and share the source code of your application. If you wish to use this software under Open Source Licensing, you must contribute all your source code to the open source community in accordance with the GPL Version 23 when your application is distributed. The main licensing options available are GPL V3 or Commercial: Open Source Licensing GPL V3 This is the appropriate option if you want to share the source code of your application with everyone you distribute it to, and you also want to give them the right to share who uses it. ![]() This software is Copyright (C) 2010-2021 Mike McCauley. It is not to be confused with any other similar marks covering other goods and services. The AccelStepper mark was first used on Apfor international trade, and is used only in relation to motor control hardware and software. If this library has helped you save time or money, please consider donating at or here:ĪccelStepper is a trademark of AirSpayce Pty Ltd. We try hard to keep it up to date, fix bugs and to provide free support. This library is offered under a free GPL license for those who want to use it that way. See for examples that work with Adafruit Motor Shield V2. The included examples AFMotor_* are for Adafruit Motor Shield V1 and do not work with Adafruit Motor Shield V2. 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. You can also find online help and discussion at Please use that group for all questions and discussions on this topic. 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.
