This project was developed initially as a way to showcase how CAN works. It illustrates the powers of a DBC file. The CAN messanges sent in this project use the Nissan Leaf 2018 as a template, however I am hopefully planning on making this non-vehicle specific.

This project only works on Linux machines as canutils is only available on Linux.

vcan.sh - This script sets up the Virtual CAN

The Python components of this project interact with the CANbus directly. Below are some of the components and their functionalities.

This is the file that sends the actual CAN messages. Once you open the file by using python sender.py, you can adjust any of the parameters. Keep in mind that the virtual CAN bus must be initialized first.

This file is a simple file which simply increments the speeds and sends it through the CAN bus. It will loop this forever and is a great way to test if everything is performing as expected.

This is the file that mimics the behavior of the listeners on a vehicle. It will listen to the CAN messages on the virtual bus and display them accordingly.

This is the file that triggers behaviour based off CAN messages. Currently, it is hardcoded to turn the blinkers on if a door is open, however there are plans to make this modular soon.

To communicate with the Java web server, the CANX Receiver code will communicate to the Java Reciever via sockets.

Dumps are a great way to log the CAN messages outputted by CANX as well as real car data such as the nissan_leaf_candump.log.
