interrupt with push buttons through Linux

lila780 · 12-29-2008, 09:09 AM

Hi!

We're trying to connect a push button to an ingenic processor, which should generate an interrupt. How do we make the connection between user space in Linux and a certain register in the processor? Do we have to write a device driver to register an interrupt handler or can we use something already existing?

We're thinking about using a thread in user space to monitor the interrupt status, but we don't know how to make the connection with the hardware.

Thanks!

You really should have this in the programming section. I'd contact a mod to ask him/her to move it.
