i need to know the pin for the interrupt 0 on Arduino Due but i don't know how to use the attachInterrupt() function,
i come from an arduino mega where for a 433RF receiver i used mySwitch.enableReceive(0); that is the pin 2 on that...
with the RCSwitch library...
Due has interrupt support across all pins, you use the pin number.
Have a look at the source code in WInterrupts.c for the sam branch and you'll see that
the first argument is called "pin", not "interruptNum" as in the avr branch
