Example code:

import time

from pydxl import Mx28, SerialLink

link = SerialLink(
    device="/dev/ttyUSB0", baudrate=1_000_000, protocol_version=1.0
)

servo = Mx28(identifier=1, serial_link=link)
servo.ping()
servo.led = True

servo.torque_enable = True
servo.goal_position = 2000
print(servo.goal_position)
time.sleep(3)
servo.goal_position = 1500
time.sleep(3)
servo.torque_enable = False

link.close()

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation

Python Dynamixel could always use more documentation, whether as part of the official Python Dynamixel docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/vpoulailleau/pydxl/issues.

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up pydxl for local development.

  1. Fork the pydxl repo on GitHub.

  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/pydxl.git
    
  3. Install your local copy into a virtualenv. Set up your fork for local development:

    $ python3 -m venv venv
    $ source venv/bin/activate
    $ cd pydxl/
    $ python setup.py develop
    
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature
    

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass whatalinter and the tests, including testing other Python versions with tox:

    $ flake8 pydxl tests (TODO use whatalinter from python-dev-tools)
    $ py.test
    $ tox
    
  6. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
    
  7. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.
  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.
  3. The pull request should work for Python 3.6, and 3.7. Check https://travis-ci.org/vpoulailleau/pydxl/pull_requests and make sure that the tests pass for all supported Python versions.

Tips

To run a subset of tests:

$ py.test tests.test_pydxl

Deploying

A reminder for the maintainers on how to deploy. Run:

$ ./deploy.sh
