You cannot do that. FPGA do not have any plotting / gui routines.

You could have a look at https://www.mathworks.com/products/vision-hdl.html -- since it would theoretically be possible to compute every pixel for what you want to display on your GUI.

thank you that was really helpful.

can you please explain what do you mean by improve gui interface?

Well, an 8 x 8 pixel display is really hard to work with -- just barely big enough for one character. But the work of guimp shows that you can do useful work in 18 x 18 pixel (though, mind you, the author of guimp had multiple colors and intensities to work with.) So if you were to take 4 raspberries and arrange them in a square, then you would have 16 x 16 pixels to work with, and perhaps that would be enough to do something readable with. Maybe not, considering there would be a gap between the 8 x 8 subsections.

Perhaps it would be better to arrange the four in a row so you could use four character words like 'stop' and 'run?'.

Hmmm, maybe even just one board would be enough. You could cycle through symbols like up-arrow and down-arrow, and the user could just wait until the one they wanted came around again and press (whatever) then. Or if you added in the joystick you could do one character at a time the way that you enter your name in the high score of a video game.
