Hi,
I want to add a function handling nested interrupts for the controller. Could you tell me the right position to add this function?
startup-file:
Undef_Handler B Undef_Handler SWI_Handler B SWI_Handler PAbt_Handler B PAbt_Handler DAbt_Handler B DAbt_Handler ;IRQ_Handler B IRQ_Handler IRQ_Handler B irq_fnct FIQ_Handler B FIQ_Handler irq_fnct //do some stuff - nested interrupt
I've add one breakpoint to the irq_fnct but it seems that the programm will not reach this part if a interupt occur.
I'm working with the atmel controller AT91SAM7S.
best regards Peter
The way to set a lot of global variables for each event (e.g deleting arp cache) and poll them in the main routine, sounds a little bit unefficient to me.
So you're betting your project on a known bitter, hard-to-do cure, against a vaguely perceived disease.
In other words, your intended cure is causing worse problems than you have right now. So why pursue it, ignoring the advice you've come here to ask for?
