hi all
i have a fitlet rm xa10 and i am trying to work with the GPIO connector under c++
i can load the GPIO and read the value but i want to use select in order to see when the value changes. the problem is the configuring the GPIO i do not get the "edge" file, according to the kernel documentation this means that the GPIO cannot be configured for an interrupt so i cant use select or poll on the value
try inotify too but it does not recognized that the file was modified.
any idea what else i can do?
interrupt from GPIO
Re: interrupt from GPIO
hello Irad
i did consulted with that page, but i didn't found the answer i was looking for.
as i said i can work with the GPIO just fain, the problem is that it seems that the GPIO ports couldn't be configured for interrupts.
at the moment i have a solution that works with pulling the value file but i don't like it.

Re: interrupt from GPIO
Which OS are you using (Windows / Linux).
I will forward to the corresponding SW engineer.
