Raspberry PI library for MFRC522.
Example program, Read.cpp, which will read rfid cards.
This library uses the bcm2835 library found at: http://www.airspayce.com/mikem/bcm2835/bcm2835-1.50.tar.gz
Fetch the tar-file and install it:
tar zxvf bcm2835-1.xx.tar.gz
cd bcm2835-1.xx
./configure
make
sudo make check
sudo make install
To build:
g++ MFRC522.cpp Read.cpp -std=c++11 -lbcm2835
