Hi there. As the title suggests, I am hoping someone could give me a link to a working MFRC522 which implements UART interface instead of SPI.
I found one here https://github.com/zodier/MFRC522-UART-Arduino
But it does not work. And the author seems not to bother about it anymore.
I don't have quite the programming skills to refer to the datasheet and write the library myself. Therefore, if there's anyone willing to implement it, please do so.
