I know there must be tons of people using embedded Linux for years that know the answer to this. Regards, Evgenii Prun, Moscow, Russia. I would be interested in seeing some application implementation examples as well. I am sure something is done in linux 2. Many AT91 evaluation kits uses this interface.

Protecting the IoT with Invisible Keys. That is exactly what I gpjo looking for. Let’s say we want to use GPIO5 as output. The Device Tree is for configuring the board, and are used by the device drivers in the kernel. Last edited by jcarrillo on7: If your applications are not using any GUI libraries then using sysfs is the most straightforward method.
Configure gpio pin as output: User space programs will be able to use these buttons via event interface. Before Asking I’ve reviewed these documents: Chronological A9t1 First Hi this should be trivial – but still too much for me.

How do i find or where is this table definig the banks? Glad I am not the only one trying to figure this out. Sign in Sign in Remember me Forgot username or password?
I have always used micros in bare metal fashion and have always had direct control to drive GPIO ports however I wanted. Regards, Evgenii Prun, Moscow, Russia. Hi, With Linux versions v3. I know there must be ,inux of people using embedded Linux for years that know the answer to this.
