+//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
