PiCAN

Can a Raspberry Pi collect CAN control frames, conveniently classifying messages and categorizing corresponding communications into clusters? I hope it can...

Setup

This program was developed on a Raspberry Pi 3 with Python 3.9.2

To get started, clone this repo onto your Raspberry Pi and navigate to the repo in the terminal!

For best practices, its recomended to setup a python virtual environment to avoid conflicting with the packages which may or may not already be globally installed. In the terminal, run the following to create a virtual environment called 'venv'

$ python -m venv venv

Next enter the virtual environment.

$ source ./venv/bin/activate

You should notice that your terminal now appends (venv) to the current line

The last order of business is installing all of the python packages required for this program. (These packages and their specific version number are stored in the requirements.txt file)

$ pip install -r requirements.txt

VCAN linux interface

In the absence of a robot and real hardware, you are able to start up a virtual CAN interface using socketcan in the linux terminal:

$ sudo modprobe vcan

Create a vcan network interface with the specific name "vcan0"
$ sudo ip link add dev vcan0 type vcan
$ sudo ip link set vcan0 up

You can then send arbitrary CAN messages via the can-utils command line tools:

$ cansend vcan0 0FF#00112233
$ cansend vcan0 ABCD0123#010203040506
$ cangen vcan0 -v
