Not a Tesla App · How Tesla is Replacing the Age-Old CAN BusTesla is replacing the decades-old CAN bus with a new, modern network architecture for in-vehicle communications.

I knew there was some level of canbus on a car, just never thought of tapping into it to make instrumentation or plot params.
It's a long video, some fits and starts as he troubleshoots hardware and then isolates data. First five minutes and then jump to 33 and then 45 minute marks if you're in a hurry.
The graphics library he used:

A Game Boy Speedometer, just because you can.
The “world’s worst digital dash”, a Nintendo Game Boy as a digital speedometer. Interfacing the handheld with the vehicle’s CAN bus system, this project has something to offer.

![Months of work have gone into decoding the Game Boy’s data bus and creating a schematic for the interface board. Tricking the Game Boy into thinking it was loading a game, while actually displaying incoming speed data. The screen’s low resolution and slow refresh rate rendered it barely readable in a moving vehicle. But [John]’s goal wasn’t practicality — it was just proving it could be done.](https://nerdculture.de/system/media_attachments/files/114/251/391/317/762/186/original/f1ea811e6cb4c4c3.jpeg "Months of work have gone into decoding the Game Boy’s data bus and creating a schematic for the interface board.

Showing real-time vehicle speed on the Game Boy sounds like it should be relatively easy, but the iconic game system wasn’t exactly built for such a task. Its 2 MHz CPU and 160×144 pixel dot-matrix screen were every kid’s dream in 1989, but using it as a car dashboard is pushing it. To bridge that gap, [John] designed two custom circuit boards.
One interfaces with the Game Boy, intercepting its memory requests and feeding it data from a microcontroller. The other processes the CAN bus signals, translating speed information into a form the Game Boy can display. [John] used inexpensive tools and software to read the CAN bus data, and used GBDK-2020 to write the software in C.](https://nerdculture.de/system/media_attachments/files/114/251/392/340/955/496/original/f54a186d63357559.png "[ImageSource: John Sutley]

With the Kali Linux 2025.1 release, i'm happy to said that CAN Arsenal as been released as well!
https://www.kali.org/blog/kali-linux-2025-1-release/
Here is a quick demo of @kalilinux #NetHunter CAN Arsenal. Im using a CAN USB Analyzer and Arduino with a CAN bus shield to emulate Car signals.
As its Experimental, you may face issues. If needed, contact me for guidance!

STM32 Tutorial #49 - More CAN filtering
In this video we will go into more details about CAN filters and we will be using a real CAN bus and a CAN transceiver.

Version 1.1.0 of CANnectivity, an #OpenSource USB to CAN adapter firmware based on @zephyr, is now available!
This release is based on the just released #Zephyr v4.1.0 and brings, among other things, explicit support for a number of popular USB to CAN adapter boards.
More details available in the #CANnectivity v1.1.0 release notes: https://github.com/CANnectivity/cannectivity/releases/tag/v1.1.0

STM32 Tutorial #48 - HOWTO use CAN
In this video we will be using CAN loopback to send and receive CAN messages. We will be creating the necessary filters to determine which CAN messages are received.

Our RTEMS CAN API with CAN FD and priority class queues (result of Michal Lenc’s thesis) has been accepted into RTEMS.org mainline. The related article Scheduling of CAN Frame Transmission when Multiple FIFOs with Assigned Priorities Are Used in RTOS Drivers was presented at International CAN Conference 2024. The maximal gateway latency under load with CTU CAN FD IP core on Zynq (MZ_APO) is under 65 µsec. Development of two more controller drivers is under development and we hope to find some GSoC participants to support even more hardware as well. #canbus #realtime

I published my Documentation of CAN Arsenal for @kalilinux NetHunter
https://v0lk3n.github.io/NetHunter/CAN-Arsenal/documentation
It should be released as experimental version in 2025.1!
I will keep updating it and add functionality to it!
You can also find it in Official Kali Linux Documentation :

I will talk about #realtime Linux kernel support, applications and history at #FOSDEM 2025 based on our experience at #CVUTFEL and my company for robotics, automotive communication ( #CANbus ), etc. The talk is based on my last year Czech language talk for the local community (Slides in English) reporting about PREEMPT_RT mainlining. Discussion and suggestions for slide fixes/extensions are welcomed as my talk has been accepted as no other better has been offered by more knowledgeable developers.
