Use SPI or I2C for NFC/RFID expansion



  • Re: [Omega2+](SPI and NFC/RFID)

    Hello everyone!

    I was wondering if it's possible to use SPI or I2C with the NFC/RFID expansion (together with Omega2+ and an expansion board) and could actually help me with the process!

    Thanks in advance!



  • Hello, We have the same goal.

    Right now I only have ways to tell you how it doesn’t work. I hope in the next few days I can tell you something more.
    I think that with the Onion package, you can only read the PN532 from the UART.
    Our goal now is to compile version 1.8 of the libnfc (https://github.com/nfc-tools/libnfc/releases/tag/libnfc-1.8.0) to use the PN532 from I2C and then replace pn532 with pn7150, which is more current and cheaper.
    If you get anything publish it please, I’ll keep you informed.
    Regards
