A Particle library for sending and receiving data using CAN bus with MCP2515. Based on https://github.com/sandeepmistry/arduino-CAN, with small changes to be compatible to Particle.
The library is only tested with the mesh modules Argon, Boron and Xenon. Older generations have an on-chip CAN controller.

| Microchip MCP2515 | Particle |
|---|---|
| VCC | 5V |
| GND | GND |
| SCK | SCK |
| SO | MISO |
| SI | MOSI |
| CS | 10 |
| INT | 2 |
CS and INT pins can be changed by using CAN.setPins(cs, irq). INT pin is optional, it is only needed for receive callback mode. If INT pin is used, it must be interrupt capable via attachInterrupt(...).
