I have two questions, I would like to ask:
1, my target front end is MFRC630, in the official website download card reader library no MFRC630, is the same download CLRC663? If not, where should MFRC630's card reader library be obtained?
2. I open the CLRC663 sample library: some of the NfcrdlibEx4_MIFAREClassic, functions cannot be implemented, is the supplied .C file incomplete?
