Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world.
SAE J1939 is used in the commercial vehicle area for communication throughout the vehicle, with the physical layer defined in ISO 11898. A different physical layer is used between the tractor and trailer, specified in ISO 11992.
This package is dependent on, was a part of, and broken out from, the python-can project that Brian Thorne has maintained for years..
This codce currently is compatable with the python-can version 3.3.2. After you clone the python-can repo be sure to checkout the 'release-3.3.2' branch
The Controller Area Network is a bus standard designed to allow microcontrollers and devices to communicate with each other. It has priority based bus arbitration, reliable deterministic communication. It is used in cars, trucks, boats, wheelchairs and more.
The can package provides controller area network support for
Python developers; providing common abstractions to
different hardware devices, and a suite of utilities for sending and receiving
messages on a can bus.
In all of my code that used the former protocol import from python-can I needed only to make a small change. Generally a shortning of the import statements.. For example
from can.protocols import j1939
becomes
import j1939
The library (should) support Python 2.7, Python 3.3+ and run on Mac, Linux and Windows; however, at this early time I am only testing on Python 3.4.0 on Linux 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
If you run into bugs, you can file them in issue tracker. (Any help is appriciated!)
