Honored ContributorIntegrating a custom component in SOPC [+IRQ]
Hello i made a custom component and integrated it on SOPC, my problem is the IRQ signal... i am using Linux in my NIOS2 and i need to make a device driver to control my custom component, however i have no control signals like :
-enable_irq -irq_reg signal to clear when a irq happens and etc. The PIO has more signals than the IRQ Avalon interface... When i export my IRQ as a conduit in my custom component and then import it as an input std_logic port /PIO to the NIOS2 i have all these control registers... any suggestions?12 Replies
Altera_ForumGuys, one question..
I need to use the alt_irq_resgister to control the interrupts in my project? If I use it, the interrupt will be treated exactly when it happen or when the code executes the alt_irq_register instruction? Ps: I need integrate a interrupt handler in my code that allows attend the interrupt when it happens.- Altera_Forum
once you register your handler with alt_irq_register, it will be called as soon as the interrupt fires, except if the interrupts are masked.
