hy,

 

 

 

I have some problem to understand how can i use an interrupt? if anybody can explan me.

 

 

 

I have a BF548 with a key pad, i can detect the interrupt with test_event.

 

i have a 2008R1.5-RC3 release.

 

I want to use this interrupt in an application but

 

how can i found the irq number?

 

what are the header that i have to add?

 

to link a fonction to an interrupt i have to use request_irq. have you an example of this function?

 

 

 

The question is maybe stupid but i haven't succes to create my routine interrupt

 

thanks

we have a documentation wiki that you know about.  please search it before asking questions:

http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:interrupts

 

i dont know which key pad you're talking about, but if you're just using the BF548 on-chip key pad peripheral, we already have a driver for it so there is no need to write your own

if you're having trouble reading a document, describe what you're missing.  dont just ask for documentation because we'll just point to a page to go read.

 

the bf54x keypad driver is documented here:
