Title: A13 GPIO interrupt source
Post by: lionel_c on October 12, 2013, 09:23:29 PM

hello !
I need some help about the configuration of my GPIO's as interrupt source.( A13 olinuxino)
I work on Debian using language C.
Usually I work with microchip PIC but I try to understand how does it work with embebbed linux.

I just found a tutorial using cat and echo to read and write gpios status but i need more information about interrupt working.

thank you

The only doc I know for these chips is all on the website...

There's not much if anything else (for these boards / chips).

You can use that code: https://www.dropbox.com/s/3svplzr1nxg0pcu/gpio.c (https://www.dropbox.com/s/3svplzr1nxg0pcu/gpio.c)

For interrupts search 'edge gpio linux'. You can use gpio_set_edge() ;)
