Hi,
using new libgpiod / chardev driver, is there any way to get state of
output? I mean one process sets it for example to 1 and another process
reads this output state for example to show that on web page.
I have to say that old sysfs interface was more user friendly...
And at second: it would be better to NOT "the state of a GPIO line
controlled over the character device reverts to default when the last
process referencing the file descriptor representing the device file
exits." "Set and forget" behavior is more natural to what some gpios are
used. For example resetting external modems, need set 1 for short time,
then to 0 and leave it for long long time until next reset is needed.
It's non sense to keep running some process only to keep output at 0.
Thanks
Jiri
