CircuitPython driver for the Adafruit STSPIN220 Stepper Motor Driver Breakout Board


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.

`Purchase one from the Adafruit shop <http://www.adafruit.com/products/6353>`_

Installing from PyPI
=====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-stspin/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-stspin

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-stspin

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install adafruit-circuitpython-stspin

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install adafruit_stspin

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import time
    import adafruit_stspin220
    import board

    STEPS_PER_REVOLUTION = 200

    STEP_PIN = board.D5
    DIR_PIN = board.D6
    motor = adafruit_stspin220.STSPIN220(STEP_PIN, DIR_PIN, STEPS_PER_REVOLUTION)
    motor.speed = 60

    total_microsteps = STEPS_PER_REVOLUTION * motor.microsteps_per_step

    motor.step(total_microsteps)
