Hi I would like to have a thread read the state of an input pin while also having an event handler for it. The reason for this is that I am exposing an interface to an external app which needs to be able to both ask for the state of a pin and receive information about pin state changes. However, si…

I solved this by ditching the legato gpio api and is instead using the sysfs implementation of the gpio driver. This I can safely do from multiple threads.

Yes I have. But sadly we are about to receive hardware today so I’m a little late for asking for changes in HW. I have tried to make another thread for GPIO read and then use an API for communicating between the two threads, but I haven’t been able to make this work. Can’t even make the helloIpc ex…

Actually, you should be able to achieve this once the API IPC issues are overcome. Layered Publish-Subscribe Handlers could be useful for notifying clients of state changes, too. I’ll take a look at your other thread.

It is exactly something like that I will build up if I can get the API stuff to work.
