rc522-rfid

node.js module to access a rfid reader with rc522 chipset which is connected a raspberry pi

Purpose

This node module is to access RFID reader with a rc522 chipset (e.g. http://amzn.com/B00GYR1KJ8) via GPIO interface of the raspberry pi.

The module is currently only able to read the serial number of the tag which is hold onto the reader.

The RFID reader is plugged onto the raspberry pi like it is described over here http://geraintw.blogspot.de/2014/01/rfid-and-raspberry-pi.html
The GCC compiler is installed sudo apt-get install build-essential
node-gyp is installed npm install -g node-gyp

First of all we have to install the C library for Broadcom BCM 2835 as it describe` here

wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.35.tar.gz
tar -zxf bcm2835-1.35.tar.gz
cd bcm2835-1.35
./configure
sudo make install

Then we can install the rc522 rfid nodejs module

npm install --save rc522-rfid

var rc522 = require("rc522-rfid");

rc522(function(rfidSerialNumber){
    console.log(rfidSerialNumber);
});
