CAN Sniffer is a MCP-2515 based Arduino firmware that extracts useful CAN data from an OBD-II port.
Currently only tested on 10th Generation Honda Civics (FC/FK).
The only external hardware required for this is a CAN controller. This firmware is built for a MCP2515 controller.
Although you can use regular wires to connect to the OBD-II port of the car, it's recommended to purchase an OBD-II extension/splitter cable for easier access.
Firmware can be built using the Arduino IDE and the following libraries:
- Packet Serial (Version 1.4.0)
- autowp-mcp2515 (Version 1.03)
Install the required libraries using the library manager. Afterwards connect the board and upload it.
