Step/Dir provides a low-level interface which abstracts over stepper motor drivers that are controlled through STEP and DIR signals. Higher-level code written against its API can control any stepper motor driver supported by Step/Dir.

Step/Dir does not provide any higher-level features like acceleration ramps. It is intended to be a building block for code that implements these higher-level features.

Right now, Step/Dir supports the following drivers:

• DRV8825
• STSPIN220

Please check out the documentation to learn more.

Step/Dir is usable, but still under active development. Its API is going to change, as more features and support for more drivers are added.

Step/Dir is maintained by:
