Hi,
can anyone help me undestand how i can link my QT application to the push button of my fpga board. For example i would like to have MY QT application display a messag when the PushButton is Pressed.

Hi and welcome to devnet,

Where will your application be running ?

Hey so far i have it runnning on the board.

How is that button seen by your system ?

[lion_roar]

i believe it is seen as a memory location. I designed the FPGA layout and used that to build a PetaLinux system. I can succesfully test all the Leds and Pushbutton in the linux terminal using the demo application provided.

Then you should extract the necessary components from the example in order to create a small library that can be used to get the information you want.

I had the exact same idea. It didnt go well the folder of said GPIO-demo app contains a .c file , a make file, and a .bb file . Are those importable into QT.

Qt is a C++ framework, so yes you can use C code.
