Hello,
For a Linux application in BeagleBone I want to be notified about gpi changes as fast as possible. I though inotify could be a good option but changes on /sys/class/gpio/gpioxxx/value files do not generate modification events. I guess this is so as the files are memory mapped and do not follow the standard kernel filesystem calls.
Any idea which approach to follow? The only concerns are: i) be notified as fast as a change occurs, ii) consume the minimum possible cpu
Regards
