    RFID RC522 on Raspberry PI with NodeJS (I2C version)

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

    Fork of

    https://github.com/ocsacesar/rc522 modified for accessing i2c version such as RC522 I2C V1.1 and reworked to async addon based on https://github.com/paulhauner/example-async-node-addon

    Update: you can now configure which pin is connected to RST Pin and which i2c address is used.

    Purpose

    This node module is to access RFID reader with a rc522 chipset (e.g. link to ebay) via GPIO interface of the raspberry pi.

    Functionality

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

    Example

    var rc522i2c = require("rc522-i2c");
    
    console.log('Ready!!!');
    // pin RPI_V2_GPIO_P1_37 see bcm2835.h, i2c-address,callback 
    rc522i2c.getSerial(26,0x28,function(rfidSerialNumber){
        console.log(rfidSerialNumber);
    });
    

    Save and run: (Is necessary "sudo")

    sudo node rfid.js
    

    NOTE: Running as root NOTE: if you use multipe i2c devices, make sure that the bus is free. I had issues with an RTC so i have to disbable the overlay in /boot/config.txt.
