I'm trying to read RFID tag using a MFRC522 module.

Connections to Nano are:

SDA                       D10        
SCK                       D13         
MOSI                     D11         
MISO                     D12         
IRQ                       N/A        
GND                      GND         
RST                       D9         
3.3V                      3.3V

With these connections the tag is read correctly with the standard Arduino code for the MFRC522 RFID module.

Anyone have any thoughts on how to use the LabVIEW SPI functions in the Arduino Compiler for LabVIEW to read an RFID tag?

The attached LabVIEW program does not work. I've tried the "SPI Open Express" inside and outside the while loop as well as "modes 0 to 3". with no luck.

Thanks.
