Hello, Is there a preferred way of providing shared access to a gpio pin?Use case is such that there is one application which only monitors the state of gpio pins, while another
actually controls those pins. It would be enough if the monitoring application could read the state of those pins regularly.
With the old sysfs approach, it was rather easy to share read/writes to a certain pin, but is there a
way to provide similar functionality with gpio character devices? Tomas
