PCI-6254 Interrupt Setup

[studio_uk]

Hi, I'm writing a card driver using RTX, DDK and the NI PCI-6254,

I've managed to init the card and can read channels fine as long as I enter a loop, i.e.

m = 0

while (!board->AI_Status_1.readAI_FIFO_Empty_St())

{

        ... read FIFO data
}

this works perfectly, however, For my particular application I need to use interrupts because the response to an event

has to be very very fast. the problem i'm having is I can register the interrupt on the correct pin, however cannot get the

card to generate any interrupts. the provided examples by NI don't have any that use interrupts.

Does anyone know how to set up the registers for FIFO_NotEmpty interrupts on an M Series card?

Thanks

John

Hi,

  sorry to be a pain. All Measurement Hardware DDK toolkit support is actually done from here :
