README
## Welcome to the Yes We CAN repository
This repository contains tools and resources for the Yes We CAN project of [Canis Labs](https://canislabs.com). There are several related projects here:
- Support for the [Canis Labs](https://canislabs.com) [CANPico](https://canislabs.com/canpico) (an add-on CAN hardware board for the Raspberry Pi Pico)
- CANHack toolkit (a proof-of-concept low-level CAN protocol hacking library)
- Sigrok CAN protocol decoder (allowing PulseView to decode CAN frames and indicate exceptional low-level protocol events)
- A Python tool for creating CAN frame bit sequencesCanis Labs CTO Dr. Ken Tindell writes about CAN on his blog at: https://kentindell.github.io
## Canis Labs CANPico hardware support
MicroPython firmware and documentation is in the `CANPico` folder. In addition, there is support for
C included in the Canis Labs CAN SDK for C, which has drivers for the MCP25xxFD (the MicroPython firmware
uses this CAN SDK to provide a MicroPython CAN API).The Canis Labs CAN SDK repository is:
[https://github.com/kentindell/canis-can-sdk](https://github.com/kentindell/canis-can-sdk)
and contains a "hello world" application using the CAN API, with pre-built firmware for the Pico and Pico W
with the CANPico board.## CANHack toolkit
The CANHack toolkit is a proof-of-concept toolkit of different CAN protocol attacks, showing
the viability of low-level bit-banging attacks on the CAN protocol itself.It is provided as generic C source code in two files:
src/
canhack.c
canhack.hIt has been built into the Canis Labs MicroPython firmware for the Raspberry Pi Pico and Pico W
for the following hardware:- Canis Labs [CANPico board](https://canislabs.com/canpico/)
- Canis Labs CANHack board (this uses the same firmware as the CANPico)
- Car Hacking Village DEF CON 30 badgeThe MicroPython firmware for the CHV DEF CON 30 badge is located in:
pico/
micropython/
firmware-20220805-CHV-DEFCON30.uf2Documentation for the MicroPython CANHack API is in:
CANPico/
docs/
CANHack MicroPython SDK reference manual.pdfThe Canis Labs [CTO blog](https://kentindell.github.io) has more information
[on the CANHack toolkit](https://kentindell.github.io/categories#CANHack), including details on how
to make a CANHack board using breadboard. There is also
a [CANHack toolkit demo video](https://youtu.be/dATyoWOlEJU) that goes into detail on how to
use the toolkit from Python, the CAN protocol hacks it
includes, and demonstrates it attacking CAN frames in real hardware (NB: the video uses the STM32-based PyBoard,
but the API is the same).## Sigrok CAN protocol decoder
A [Sigrok](https://sigrok.org) protocol decoder for CAN 2.0:

can2/
__init__.py
pd.pyThere is a [PulseView and can2 demo video](https://youtu.be/RvExJSDvhKo) showing how to use PulseView
as a logic analyzer and seeing CAN frames at a low-level.The [CIA CAN newsletter](https://https://can-newsletter.org) has published an [article](https://can-newsletter.org/tools/tools-miscellaneous/210607_can-decoder-warns-for-malicious-attacks_cnlm_ken-tindell) describing the protocol decoder and showing how it can spot some CAN protocol attacks.
## Python CAN tool
Python tool for creating and parsing a CAN bitstreams (including creating Janus attack frames):
