Node-RED support for Sparkfun CAN bus shield. can send and recieve canbus data via the sparkfun canbusshield.

module.exports = function(RED){

    var mraa = require('/usr/lib/node_modules/mraa/mraa.node'); // require mraa

    function LEDD7(n){
        //init

        LedGreen.mode(mraa.PIN_GPIO);                 //set pin mode to gpio 
        LedGreen.dir(mraa.DIR_OUT);                   //set to ouput

        this.on('input', function(msg,send,done) {    // do this when there is a input message     
            
            if (msg.payload == true){
                LedGreen.write(1);                    // if input == true/1/red => led on
            }   
            else{
