I have this problem with my VHDL code.
if pointer <= (top_pointer) and test = '0' then
LED <= LISTEN(pointer);
pointer := pointer + 1;
end if;
The Idea with this piece of code is that as i've tried to state is as
long pointer is less than top pointer, LED has to display what inside
the array listen and then increment the pointer.
the problem is that it isn't showing what the array contain.
My theory I am missing a prescaler, so i tried adding one,
if pointer <= (top_pointer) and test = '0' then
if(prescaler < 49999999/1) then
prescaler := prescaler + 1;
else
prescaler := 0;
LED <= LISTEN(pointer)
pointer := pointer + 1;
end if;
end if;
but still same result..What am I doing wrong here??
You do not attach the questionable VHDL code. So no one is able to see the definition of the types... Why do you open a new thread for an old question?

My code is attached in my old thread. Yes there is a clock attached in my design??

For all the others: http://embdev.net/topic/332350 > Yes there is a clock attached in my design?? It is, but up to now I did what I said: not reading an external link to your code.

BTW: You are playing a high league with this here: shared variable top_pointer: integer range 0 to 4 := 0; I rarely need a shared variable. And if so it is only for simulation. Can your synthesizer handle shared variables?
yes... it is cappable of handling it.
