A golang library for rc522 rfid reader.
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 go librayr 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
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
Next run your go code.
