Interruption program

Hello, I am trying to do an interruption of a video signal. I am using the hsmc quad video card of Bitec associated to a cyclone III C25 Altera card. An interruption is supposed to be generated...

Hello,

Sorry but I am not sure of what you say (I have to improve my english). If you don't have interruption the video works. And if you enable it, it does not work. Is that correct, or it never works ?

If it never works, I have no idea because I never works with this design. So what I recommend is to use the default design provide by BITEC, check that it works, and modify it little by little until you have what you want.

If it is the interruption that cause problem, like that I don't see where that can coming from. Maybe if you can give details of the different steps of your program please.

Else, I missed it before, but you should change the following (I don't know the effect that can have) 


if (pouet == 1)
    {printf("coincoin");
        pouet == 0;
    }
