Good morning,

i have the HSYNC signal provided from a camera, my processor is Blackfin BF 548 and th SO is ucLinux.

I need to read this signal from PPI port, but if i read this signal with GPIO function i have a lot of problem because is too fast!

I would like configure in kernel space a interrupt and read this interrupt feedback in user space.

How do i configure an interrupt in ucLinux in kernel space and read a feedback in user space?

Thanks
