In this post I prepared what I think is the simplest example on how to manage interrupts for the widespread ARM926 core. From this example one can expand the complexity of the interrupt management at will. I’m going to test the functionality with QEMU, emulating the Versatile Platform Baseboard. I based this example on my […]
