I am using stm32 nucleo board for rfid but I can’t use IRQ pin of MFRC522 module. Also there is no rc522 library that has configured with IRQ pin of MFRC522 module.

Hello,

that is not good description. Why you can not use the IRQ pin?

What a library? I do not know which one use are using.

So this one? MFRC522 - RFID Chip MFRC522 driver | Mbed
This library seems to be based on pooling menthod and that will be the reason. However you can try to use InterruptIn Mbed API together with the library.
