Step/Dir - Universal Stepper Motor Interface

Please consider supporting this project financially. More information below.

About

Step/Dir aims to provide an interface that abstracts over stepper motor drivers and controllers, exposing high-level hardware features directly where available, or providing software fallbacks where hardware support is lacking.

Step/Dir is part of the Flott motion control toolkit. Please also check out RampMaker, a library for generating stepper acceleration ramps. In a future version, both libraries will be integrated, but for now they can be used separately to complement each other.

Right now, Step/Dir supports the following drivers:

DRV8825 (crate)
STSPIN220 (crate)

Support for more stepper drivers and controllers will be added in the future. Please consider helping out with this effort, if you need support for a driver or controller that is currently missing.

Please check out the documentation to learn more.

Status

Step/Dir is under active development. Its API is going to change, as more features are added and existing ones are improved. Support for drivers is very limited right now, and support for controllers is non-existent.

The library is usable, but far from mature. If you find any problems, please open an issue on the GitHub repository.

Step/Dir is maintained by:

Usage

Step/Dir is a library written in Rust and designed for use in Rust projects. It will run on any platform supported by Rust, including microcontrollers.

Add Step/Dir to your Cargo.toml like this:

[dependencies.step-dir]
version = "0.4" # make sure this is the latest version

If you just need to use a specific stepper driver, you can also depend on the crate for that specific driver. For example:

[dependencies.drv8825]
version = "0.4" # make sure this is the latest version

Please refer to the API Reference for more information.
