#rc522-rfid node.js module to access a rfid reader with rc522 chipset which is connected a raspberry pi
The library work with RPI v1 only. It is based on bcm2835 module. The RIPv2 has different addresses.
On RPI 2, the peripheral addresses are different and the bcm2835 library gets them from reading /proc/device-tree/soc/ranges. This is only availble with recent versions of the kernel on RPI 2.

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);
});
