//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 #include "mbed.h" #include "MFRC522.h" // Nucleo Pin for MFRC522 reset (pick another D pin if you need D8) #define MF_RESET p8 DigitalOut LedGreen(p24); //Serial connection to PC for output Serial pc(p9, p10); MFRC522 RfChip (p11, p12, p13, p14, MF_RESET); int main(void) { pc.baud(9600); pc.printf("starting...\n"); wait(1); // Init.
