Overview

UAVCAN v0 stack in Python

Travis CI Gitter

Python implementation of the UAVCAN v0 protocol stack.

UAVCAN is a lightweight protocol designed for reliable communication in aerospace and robotic applications via CAN bus.

Documentation

Installation

Compatible Python versions are 2.7 and 3.3 and newer. If the library is used with Python 3, which is recommended, it does not require any additional dependencies. If Python 2.7 is used, additional dependencies are needed - refer to setup.py for more info.

pip install uavcan

Development

Automatic deployment to PyPI

In order to deploy to PyPI via CI, do this:

  1. Update the version number in version.py, e.g. 1.0.0, and commit before proceeding.
  2. Create a new tag with the same version number, e.g. git tag -a 1.0.0 -m "My release 1.0.0"
  3. Push to master.

Code style

Please follow the Zubax Python Coding Conventions.

  • AttributeError: module 'collections' has no attribute 'MutableSequence' with Python 3.10 (ships with Ubuntu 22.04 by default)

    AttributeError: module 'collections' has no attribute 'MutableSequence' with Python 3.10 (ships with Ubuntu 22.04 by default)

    This happens because MutableSequence is now part of collections.abc; a possible fix is to change the import in transport.py to

    try:
        from collections import MutableSequence
    except ImportError:
        from collections.abc import MutableSequence
    

    which might not be the most elegant solution, but keeps support for all versions.

  • Update to DroneCAN Namespace

    Update to DroneCAN Namespace

    This PR moves to using dronecan name for python module, while retaining backward compatibility with uavcan as much as possible.

    • All older uavcan specs are now available via dronecan.uavcan
    • support for loading both uavcan_vendor_specific_types and dronecan_vendor_specific_types
    • doesn't require change to DSDLs
    • uses relative ../DSDL to load standard DSDLs

    This will need to be pushed force as this is based off pyuavcan directly

  • parser: added OVERRIDE_SIGNATURE

    parser: added OVERRIDE_SIGNATURE

    this allows for DSDL with an overridden signature, allowing for a message to be moved in the DSDL tree while maintaining compatibility with an existing vendor message

    for an example see https://github.com/dronecan/DSDL/pull/16
