I want to make RFID reader writer using CC3220S and RC522.

Please provide example code for the same.

    Issac -
    the RC522 is reader from NXP. It supports only ISO14443A and variants of that protocol.

    Texas Instruments makes TRF7963A (direct functional cross for same protocol support) and the TRF7960A, TRF7964A, TRF7970A (more NFC/RFID protocols, same IC pinout and matching circuit as the TRF7963A)

    just FYI - not sure why you prefer the MFRC522 - the TRF79xxA family beats out this part in every aspect.

    So you have several options for the hardware:
    1. You can use the DLP-7970ABP, which plugs directly into the CC3220S-LAUNCHXL, this would use SPI between the TRF7970A and the CC3220S
    and use/port this ==> forum.43oh.com/.../

    2. If you have your own MFRC522 hardware, you can use either SPI, UART or I2C (the CC3220S supports all three) - and potentially use the Energia example(s) I found here:
    forum.43oh.com/.../
    github.com/.../mfrc522-energia
    maybe there are more.
