<p dir="auto">I am trying to use the code provided here for my RFID unit: <a href="https://docs.m5stack.com/#/en/unit/rfid?id=schematic" target="_blank" rel="noopener noreferrer nofollow ugc">https://docs.m5stack.com/#/en/unit/rfid?id=schematic</a></p>
<p dir="auto">But I always get the error "no matching function for call to 'MFRC522::MFRC522(int)'" when trying with Arduino IDE, and it is not even possible to open the M5F file into UIflow.</p>
