Hi everyone,

I'm trying for handler input digital port interruptions on Ethernut 1
but I am not sure about how to use them. In Ethernut 3 the example
I've found (AT91SAM7X-EK Port I/O on NutWiki) is

NutRegisterIrqHandler(&sig_PIOA, JoystickIsr, NULL);
outr(PIOA_IER, _BV(21) | _BV(22) | _BV(23) | _BV(24) | _BV(25));
NutIrqEnable(&sig_PIOA);

But the same for Ethernut 1??

Thank you.
