[En-Nut-Discussion] How do i use PIO interrupts?

[Lars Tore Skau]

Hello.

I am currently using NutOS on the at91sam9260 dev board from olimex..
so far everything looks good, but now i need to use a gpio to trigger
an ISR..
Been looking at the samples, but can't seem to find anything similar.

What i want to do is:

Trigger pio_isr() on the falling edge of PA23

If someone could give me a short example that would be great.

Regards,
LT
