    wiegand

    A fork of node-wiegand for only 26bits wiegand readers on GPIO.
    Tested with EM-18 Reader Module on a Raspberry Pi 3 model B.

    installation

    $ npm install --save wiegand-rfid-reader
    #OR 
    $ npm install --save https://github.com/7aman/wiegand-rfid-reader.git

    usage

    const wiegand = require('wiegand-rfid-reader');
    const reader = wiegand();
    const Gpio = require('onoff').Gpio;
     
    //export d0, d1 pins
    const d0 = 17, d1 = 18;
    const wgnd0 = new Gpio(d0, "in", "both");
    const wgnd1 = new Gpio(d1, "in", "both");
    reader.begin({ d0: d0, d1: d1});
     
    reader.on('id', id => {
        console.log('Got', id, 'from RFID reader');
    });
     
    reader.on('error', err => {
        console.log(err);
    });
     
    process.on('SIGINT', () => {
      wgnd0.unexport();
      wgnd1.unexport();
    });
