An Arduino library for interfacing with the MCP2515 stand-alone CAN controller over SPI. It implements CAN V2.0B at up to 1 Mb/s with support for standard and extended frames, masks, and filters.
Use cases
- send and receive CAN bus messages from an Arduino
- build an OBD-II vehicle diagnostic device or data logger
- communicate between microcontrollers over CAN
- set receive masks and filters for CAN frames
- wire a DIY CAN node with MCP2515 and MCP2551
When to choose
- you use an Arduino or Seeeduino with an MCP2515-based CAN shield or board
- you need standard and extended CAN 2.0B frames at up to 1 Mb/s
- you want a lightweight, MIT-licensed C++ CAN driver with examples
When to avoid
- your board has a native CAN peripheral and does not need the MCP2515 chip
- you need CAN FD, which the MCP2515 does not support
- you are not on an Arduino-compatible embedded platform
