I need to Integrate with an NXP Mifare reader (crypto1) MFRC531 01T and i need some help on the related protocol commands over RS232 in order to poll for SIDs, authenticate and read block/sectors.
Hello @Menspa
Unfortunately, NXP does not provide Demo examples based on the MFRC531; therefore, you will need to refere the MFRC531 datasheet(MFRC531 Standard ISO/IEC 14443 A/B reader solution)and use NXP's library NxpNfcRdLib, to develop your card read/write application.
