explorenfc v0.0.1

What is this?

A super simple NodeJS Library to read and write NFC NDEF records on a Raspberry Pi with an NXP Explore NFC shield

Usage

Prerequesities

1. Install NFC Explore software on your device as per http://www.nxp.com/documents/application_note/AN11480.pdf
2. Install this module npm install explorenfc

Read contents

var nfc = require("explorenfc");
nfc.init("/usr/bin/explorenfc-basic");

nfc.read(function(nfcEvent){
  if(nfcEvent){
    console.log("id", nfcEvent.id);
    console.log("value", nfcEvent.value);
  }else{
    console.log("no NFC Event");
  }
});

Write contents

var nfc = require("explorenfc");
nfc.init("/usr/bin/explorenfc-basic");
nfc.write("herp derp", function(writeOrNot){
  if(writeOrNot) console.log("NFC tag was written");
});

Limitations

Functionality is kept intentionally limited to keep this module very simple to use. Because of this we don't support much functionality.

Roughly how it works

On read we execute explorenfc-basic

On write we execute explorenfc-basic –w '<your message>' –t <type>
