-//Test of cheap 13.56 Mhz RFID-RC522 module from eBay
-//This code is based on Martin Olejar's MFRC522 library. Minimal changes
-//Adapted for Nucleo STM32 F401RE. Should work on other Nucleos too
- 
-//Connect as follows:
-//RFID pins        ->  Nucleo header CN5 (Arduino-compatible header)
-//----------------------------------------
-//RFID IRQ=pin5    ->   Not used. Leave open
-//RFID MISO=pin4   ->   Nucleo SPI_MISO=PA_6=D12
-//RFID MOSI=pin3   ->   Nucleo SPI_MOSI=PA_7=D11
-//RFID SCK=pin2    ->   Nucleo SPI_SCK =PA_5=D13
-//RFID SDA=pin1    ->   Nucleo SPI_CS  =PB_6=D10
-//RFID RST=pin7    ->   Nucleo         =PA_9=D8
-//3.3V and Gnd to the respective pins
