Lets try it that way:
> As far as i know, ADC gives me some binary digits
In which format? How fast? How do you get the result?
> and i need to display it on my fpga board
The whole is in deed a simple task (it will take me roughly 2 hours),
but i am (maybe no one is) intended to do your homework.
So, do a little research on your own. When you know for sure how your
system looks, then start with the top level of your design (ports to the
ADC and the display and the clock and some switches...). Then add a
component that reads data from the ADC, and one that displays numbers on
And when you find problem during that kind of work, then you write
exactly which one and what you assume as a solution. Then, maybe,
someone will help you...
