Accelstepper

Support for stepper motors with acceleration etc. This defines a single 2 or 4 pin stepper motor, or accelstepper moter with fdriver chip, with optional acceleration, accelstepper, deceleration, absolute positioning commands etc.

This fork follows the upstream version. Files are slightly reorganized to follow Arduino library conventions to allow for inclusion into the Arduino IDE library manager. This is the Arduino AccelStepper library. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors and motor drivers. It is perfectly adequate for simple, single motor applications. AccelStepper significantly improves on the standard Arduino Stepper library in several ways:.

Warning: This is not an introductory tutorial for beginners! I'm assuming you already know what steppers are, have decided they are right for your project, and want to know how to use them better. I assume you are familiar with the Arduino environment and know how to load libraries, how to program, compile, and upload. You should also have some basic knowledge of Electronics including basic circuit skills and understanding and be familiar with breadboarding.

Note that each call to run accelstepper make at most one step, and then only when a step is due, based on the current speed and the time since the last step, accelstepper.

This article includes everything you need to know about controlling a stepper motor with the A stepper motor driver and Arduino. I have included a wiring diagram, a tutorial on how to set the current limit and many example codes. Although you can use this driver without an Arduino library, I highly recommend you also take a look at the example code for the AccelStepper library at the end of this tutorial. This library is fairly easy to use and can greatly improve the performance of your hardware. After each example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs. If you would like to learn more about other stepper motor drivers, then the articles below might be useful:. I like to use this driver in combination with a CNC-shield or expansion board. Such a shield already includes capacitors and offers an easy way to select the microstepping resolution.

Also added new Quickstop example showing its use. The desired acceleration in steps per second per second. Defaults to pin 4. Since this example simply runs a stepper at constant speed, we only need to set the maximum speed and the desired actual speed. A selection of important examples will be examined and discussed in Step 1. The motion functions are of two types: constant speed limited by the current value of speed , and variable speed limited by settings of acceleration and maxSpeed, and by position relative to the target. Reported by Oleg V Gavva. The other reason is that constant current operation is not as easy for these drivers. The default is very slow, so this must be configured. This function needs to be called often just like runSpeed or run. Here are the first two lines. Called to execute a step. Questions and comments are most welcome.

This is the Arduino AccelStepper library. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors and motor drivers.

Reported by Peter Linhart. Useful for setting a zero position on a stepper after an initial hardware positioning move. Performance improvements in runSpeed suggested by Jaakko Fagerlund. You may also invert the pins using setPinsInverted. Sets the minimum pulse width allowed by the stepper driver. Pick the library by Patrick Wasp. The default maxSpeed is 1. New option for user to set the min allowed pulse width. Returns the target position in steps. Set the speed, in steps per second. Negative is anticlockwise from the 0 position. Referenced by runToPosition. You must call run, as often as possible or any of the non-blocking run functions. Adjusting the pot on the driver, turn it all the way down, then increase it slowly until the motor performs properly.
