Flipper Zero CAN HS/FD Adapter

Description:

This project aims to develop a CAN (Controller Area Network) adapter for the Flipper Zero, allowing users to connect devices with a CAN interfaces in particular automotive ECU's.

Firmware Development:

• The CAN adapter application firmware is developed in C++ using the Flipper Zero's Xtreme-Firmware SDK.

• The application firmware must runs on the Flipper Zero, which communicates with the CAN adapter through its SPI interface.

• Firmware features:

  • CAN HS Communication
  • CAN FD Communication (partially)
  • Device detection and configuration
  • Error handling and debugging tools

• The CAN adapter is fully compatible with Linux SocketCAN enabling the usage of can-utils tooling for receiving and sending CAN messages.

See Software development folder for more information

Hardware Development:

• The CAN adapter board is designed using KiCad 7.x
• The PCB layout includes:
  • Microchip MCP2518FD CAN transceiver chip
  • TJ1051i CAN driver with galvanic isolation up to 4kV
  • Screwless CAN connector for easy plug-in
  • TX/RX CAN activity LEDs for easy debugging

See Hardware development folder for more information

Getting Started:

• Download and install the CAN adapter application
• Launch the application and connect your Flipper Zero into your PC
• Find the appropriate COM port
• Setup the Flipper USB-CAN as a SocketCAN interface :

sudo modprobe can$ sudo modprobe can-raw$ sudo modprobe slcan
sudo slcan_attach -f -s6 -o “<COM Port> (e.g. :/dev/ttyACM0)”
sudo slcand“<COM Port> (e.g :/dev/ttyACM0)” can0
sudo ifconfig can0 up

Branches:

• main: The main branch, where stable code is kept. This is the default branch that new users will see when they clone the repository.
• dev: The development branch, where experimental or feature-in-progress code lives. This allows for concurrent development and testing without affecting the stability of the main branch.
