I have connected as Follows

SDA --> SS PK6
SCK --> SCK PB1
Miso --> MISO PB3
Mosi --> MOSI PB2
RST --> PK7
3.3v --> 3.3V
GND --> GND

I am duing: init MFRC522 --> MRFC522 Antenna ON --> MRFC522 Check for card

Hi Alan,

I started investigating the component, the source project I was using as an example for the code has changed a lot since I last looked and it wasn't the best to read back then. It's pretty horrendous now.

The component as is is known to work so I wonder what might be going wrong. What type of RFID tags are you using and can you attach your program so we can try and replicate your setup.

Hi Benj

Another 2 modules just arrived today and they work perfectly
