Hello i wanted to ask a question i can't get the RC522 module for RFID to work. At first I tried first through The DumpInfo example is what I get in the terminal: "Firmware Version: 0x18 = (unknown) "Scan PICC to see UID, SAK, type, and data blocks... "But by approaching an rfid tag it is not read.

Then I tried with The Firmware_check example and the result is this: "MFRC522 Digital self test "***** "Firmware Version: 0x18 = (unknown) "----------------------------- "Only known versions supported "----------------------------- "Performing test... "----------------------------- "Result: DEFECT or UNKNOWN

Could the error be from incompatible firmware? Thank you very much

OS version: Win10 Arduino IDE version: 2.1.1 MFRC522 Library version: 1.4.10 Arduino device: Arduino uno R3 MFRC522 device: RFID-RC522

Seeing the other end of those wires would really help.

Hi! Has the problem been solved? I had the same problem.

The problem is, most likely, that you've got a poor connection on your MISO line, which is corrupting the response from the reader. How have you got it wired?

The problem is, most likely, that you've got a poor connection on your MISO line, which is corrupting the response from the reader. How have you got it wired? I have resolved that the slice selection (CS) GPIO pins on my development board are not supported. Replaced with a GPIO solution.
