Using MFRC522 NFC with Kinetis KL26 & implementing tag detect interrupt

[punitkumar]

Hi

I wish to use MFRC522 NXP reader module for my next design. I need something which interrupt the MCU if a tag is detected so that I need not always keep checking the presence of tag by polling.

Also, where can I found a code to start with?

Hello Punit,

    At first, you should know how to develope software on Kinetis MCU, you need IAR environment and load KSDK into it.

In our KSDK, you can find example code on how to enable and create a interrupt serives.

    On hardware, you need to connect a GPIO of KL26 to INT pin of MFRC522, this is the basic condition to response interrupt from MFRC522.

    note: KSDK is here --- https://mcuxpresso.nxp.com/en/welcome

Hope my advice can help you!

Have a great day,
