External interrupts

Hardware Arduino Due
9

@graynomad: in the end there will be no mapping at all..

With the Due board you must use the attachInterrupt directly with the pin number:

attachInterrupt(pin, callback, mode)

for example:
attachInterrupt(9, myfunction, RISING); // RISING edge on pin 9 => calls myfunction

There is no limit on the number of interrupt that can be defined. (Yes, you can setup a different interrupt function for each pin)

attachInterrupt() will be available again with Arduino IDE 1.5.1 (released on Nov, 5)
