Hi, Can any one provide a C code for Interfacing a RC522 RFID reader to the Beaglebone black wireless using a SPI bus.
Well, you could perhaps start with the Arduino library
https://github.com/miguelbalboa/rfid which is C++.
You'd have to replace the Arduino SPI calls
(https://www.arduino.cc/en/reference/SPI) with BBB SPI library calls
