Fixed interval timer interrupt example?

jesusmgonzalez


Hi,

I'm trying to develop a small example using this IP through interrupts. I saw some examples using Timers,
but I would like to use this IP.

Does someone know where could I get some kind of information?

Thanks,

    @TroutChaser I think you've understood @jesusmgonzalez wrong. He want to use the "Fixed Interval Timer" this Timer has no AXI connection and therefore no drivers. I have the same problem here could run the Interrupt example with the AXI Timer but not with some non AXI IP core. I've been looking for quite a while but can't find an answer. I've defined the Port as Interrupt Port and connected it via concat to the IRQ of the Zynq. It schows up with a number in my xparameters.h file but the initialization via XScuGic_Connect, XScuGic_SetPriorityTriggerType and XScuGic_Enable will trigger nothing. The GIC initialisation is done the same way as at the AXI Timer example. The only thing that is not clear is the last parameter of the XScuGic_Connect function (I've tried 0 and &InterruptController (from XScuGic_CfgInitialize)). So does someone no how to do that?
