python-can#

Controller Area Network (CAN) support for Python. The python-can package is a python library that provides a high-level and a low-level API for communicating with CAN bus devices. It provides a pythonic interface to the SocketCAN implementation found in the Linux kernel, and it supports multiple platforms and CAN interfaces. The high-level API provides a simple, pythonic interface to the common functionality required to interact with a CAN bus. This includes sending and receiving messages, filtering, and error handling. The low-level API provides direct access to the raw message data and allows more fine-grained control over the CAN bus communication. The package also provides a set of utility functions and classes for common tasks such as bit-level manipulation, error detection and handling, and message parsing.

  • Provides a common abstraction to different hardware devices

  • Has utilities for logging, replaying, and viewing

  • Implements a custom virtual interface, based on python message queues

  • Wide variety of supported interfaces:

    • SocketCAN

    • Kvaser’s CANLIB

    • CAN over Serial / SLCAN

    • IXXAT Virtual CAN Interface

    • PCAN Basic API

    • USB2CAN Interface

    • NI-CAN

    • isCAN

    • NEOVI Interface

    • Vector

    • CANalyst-II

    • SYSTEC interface

    • …

  • Runs on Linux, Mac OSX and Windows

  • Does not provide sockets or message queues. Only one application can exclusively use a CAN device

  • Python global interpreter lock

  • Depends on dll from manufacturer
