Interruption program

Hello,

I don't manage to add buttons and led to my design. Indeed, I based my design on an example given by BITEC on their website. I changed .v files but never changed SoPC files. When I regenerate SOPC without changing anything, the design does not work anymore. I have then a time limited .sof so maybe I am missing some licenses (?) and some files are not correctly regenerated (?). Therefore, I can't touch to SoPC.

However, I used your piece of advice and noticed first that like you said, I did not acknoledge the interruption which I did (it is not a PIO port but I found the way to do it). Second, my interruption signal was not generated. Now, it prints "coincoin" :) (see my first post). This means it goes to the ISR. The problem is that whether or not I generate an irq, the video (that is to say the rest of my program) does not work anymore.

At least, when there is no irq generated, the rest of the program (which is the while (1)) should work, right ? Do I have to disable/enable something ?

Do you have an idea where it may come from ?

Your help is very precious !
