hi am programming ngw in embedded linux environment ....
could any one tell me how to enable a gpio pin as an interrupt and then how
to detect the change in the signal in this pin in the program....

regards,

First, download the data sheet for the AVR you plan on using. Find the
section(s) that deal with interrupts. Everything you need to know is
there ...

hi,
the reason iam asking this question is because....iam doing on embedded
linux platform and writing a c code ....after reading the datasheets iam in
a position to set the interrupts for a pin but the problem is once an
interrupt occurs how will i know it in c?? could anyone post with a single
example i searched a lot but failed to get one in c...

regards

How much experience have you had with AVR's? I always tell people to start
out simple - get a programmer like the STK500 or Ponyprog, write some
little programs in assembler to get the feel of it all, and see if you can
do something like make LED's light up with pushbuttons, etc. Even a
simple USART routine might be too much for someone with little or no
microcontroller experience.

I'd need more info on what your setup is. I'm assuming your AVR is going
to be connected to your computer somehow. Which AVR do you plan on using
and what kind of interface are you using? How is the interrupt going to be
triggered? A GPIO pin set up as an interrupt is an INPUT. You'd have to
write code in your interrupt service routine to get the data to the
computer, and that's why we'd need to know how you plan on making that
happen.

iam not at all familiar with avr i have used pics for long...anyway right
now i use ngw100 with avr32microcontroller

OK. Well, as I said, you need to write some sort of code in your
interrupt service routine to communicate to the computer that the
interrupt has been triggered.

It appears one of the documents at the Atmel site under ATNGW100 would
answer your question.
