The way I soldered the pins on my NFC Shield makes it non-stackable.
I mean, I can plug it in my arduino, but I can't plug anything else on top of it.
That's why i'd like to know which are the pins used by the shield (so i can connect it with wires, without stacking it).
The code looks like this:
#define IRQ (2)
#define RESET (3) // Not connected by default on the NFC Shield
But I keep getting the message "Didn't find PN53x board" if I don't plug in the analog 4-5 and digital 10-3 pins.
I had a look at the library but I don't understand where the arduino polls the shield on other pins thant _irq or _reset (2 and 3).
Thanks for your help
