I am trying to access the GPIO buttons of the Pinto-Th expansion board from userspace. I can control gpio146 with no problems, but when I export the buttons gpio14, gpio22, and gpio23, they show the correct direction (in) and default value (1), but when I press the button the value does'nt change. What might be the issue here?

Is it possible that I have to configure the kernel to access those buttons? I am trying to keep it simple for now.

Thanks in advance for any help/commentary provided.
