Raspberry Pi 3 + PiCAN2 – Embedded Linux System For CAN Bus Application Development

Raspberry Pi 3 System With CAN Bus Interface
Raspberry Pi 3 System With CAN Bus Interface

The Raspberry Pi 3 is part of a series of credit-card-sized single-board-computers (SBC) developed in the United Kingdom by the Raspberry Pi Foundation. As of December 2016, the Raspberry Pi 3 Model B is the newest mainline Raspberry Pi.

All models feature an ARM compatible CPU with on-chip GPU with speeds up to 1.2 GHz and on-board memory up to 1 GB RAM. Secure digital (SD) cards are used to store the operating system. The Raspberry Pi Foundation provides Raspbian, a Debian-based Linux distribution for download.

For more information on the Raspberry Pi see https://www.raspberrypi.org/.

The PiCAN2 board provides Controller Area Network (CAN) Bus capabilities for the Raspberry Pi. It uses the Microchip MCP2515 CAN controller in combination with the MCP2551 CAN transceiver. Connections are made via a DB9 connector or a 3-way screw terminal. There is an easy-to-install SocketCAN driver, and programming can be accomplished in C or Python.
Features
  • CAN v2.0 A/B at 1 Mb/s
  • High speed SPI Interface (10 MHz)
  • Standard and extended data and remote frames
  • CAN connection via standard 9-way sub-D connector or screw terminal
  • Compatible with OBDII cable
  • Solder bridge to set different configuration for DB9 connector
  • 120Ω termination resistor
  • Serial LCD ready
  • LED indicator
  • Foot print for two mini push buttons
  • Four fixing holes, comply with Pi Hat standard
  • SocketCAN driver, appears as can0 to application
  • Interrupt RX on GPIO25
