mfrc522-cpp

Library for the popular MFRC522 RFID card reader/writer. It was forked from paguz/RPi-RFID to add support for spidev and cmake.

Prerequisites

This if you want to use apps/bcm2835_read_example/ you have to build the bcm2835 library first:

Fetch the tar-file and install it:

 tar zxvf bcm2835-1.xx.tar.gz

Build:

cd bcm2835-1.xx
./configure
make

Install:

sudo make check
sudo make install

Build

Clone:

git clone https://github.com/twyleg/mfrc522-cpp

Create build directory:

cd mfrc522-cpp/
mkdir build

Build:

cmake ../
make

Examples

The project provices two examples:

• apps/spidev_read_example
• apps/bcm2835_read_example

That use spidev or the bcm2835 library to access the SPI interface.

Note: Be aware that bcm2835 requires root priviliges and that running the spidev example after the bcm2835 example might fail (read the Troubleshooting section of the spidevpp README.md for further infos.
