This library allows you to communicate with multiple types of CAN controllers using a consistent API, making CAN communications easier through Arduino.

The idea behind this CAN library is to use a similar approach to Adafruit's Unified Sensor library (https://github.com/adafruit/Adafruit_Sensor) by standardizing CAN function calls, frame structure, filters, masks, buffers, etc to be used with a wide variety of CAN controllers. This library currently supports the following controllers:

• Microchip MCP2510 & MCP2515 through the SPI interface
  • Tested using various Arduino and Arduino-compatible controllers
• Atmel SAM3X family of MCU
  • Tested using the SAM3X8E on the Arduino Due
• Freescale Kinetis K2x family of MCU
  • Tested using the MK20DX256VLH7 on the PJRC Teensy 3.1

Since I have taken features from so many libraries I can’t tell what came from where, so in order not to violate any GPL, LGPL or any other license out there I am trying to give credit where credit is due. I am only a contributor to this library and some of the work here might not be mine. I can take credit in putting it together and releasing back to the public to make any variation as needed. This is a work in progress library with no current release.

For the MCP2515 library release see CAN_MCP2515 branch on this repo
