#88106 Hello, I have same issue.
Can you put the wiring diagram for SPI (PN532 <-> D1 MINI)
And the functional code

I used Adafruit_PN532 with commun exemple :
Code: Select all#define PN532_SCK (14)
#define PN532_MOSI (13)
#define PN532_SS (15)
#define PN532_MISO (12)

and my wiring is :
    D5 to SCK
    D6 to MSO
    D7 to MOSI
    D8 to SS
    3v3 to VCC
    G to GND
all is power with USB cable (potential problem!)
