This library provides support to AVR CPUs which contain an internal CAN controller when used with the NMEA2000 library.

See https://github.com/thomasonw/NMEA2000_avr & https://github.com/thomasonw/avr_can

Currently supported CPUs include:

• ATmega16M1
• ATmega32M1
• ATmega64M1
• ATmega32C1
• ATmega64C1
• AT90CAN64
• AT90CAN128

This library is is support of ttlappalainen's NMEA2000 library. See the NMEA2000 for more examples.
Also required is AVR_CAN driver https://github.com/thomasonw/avr_can Make sure you have it installed.

#include <NMEA2000_CAN.h>  // This will automatically choose right CAN library and create suitable NMEA2000 object
#include <N2kMessages.h>


void setup() {
  NMEA2000.open();
}

void loop() {
}

All examples using one CAN port in the NMEA2000 library will. The ATmega M1/C1 & AT90CAN CPUs only have one CAN controller.

You will need a CAN transceiver like the MCP2551
