Interrupt reading in NIOSII

870 Views

Hi,

I am very new to NIOSII programming.

So I generate an interrupt using PIO on QSYS

Direction : Input

Synchronusly capture : Rising Edge

IRQ type: Edge

I export the conduit to connect to an FPGA board pin.

What I want to do is when there is an interrupt generated on this pin I want to be able to read it on NIOSII and use it as a variable in coding.

For example I=interrupt then I want to able to write a onditional for loop

If I=1 then

else....

Does anyone know how to do this in NIOSII??
