Hi,

I really need your help in this...
I have this message after execusion of DUMBINFO.ino:

MFRC522 Software Version: 0x90 (unknown)
Scan PICC to see UID, type, and data blocks...

You library can read easly from version like 0x91 and 0x92 but I bought a new RFID reader with version 0 (0x90) and I can't read tags or cards

So how can I ungrade the reader to 0x92 or what to ajust to make my reader read cards???

Thanks

P.S : I installed the library from : GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522
and i respected the connection wires as the example

It would be very helpful if you posted the code that you are running and a link to the RFID reader.
