Pls post your code as *.vhd attachment.

I wrote in September something similar.
The size of the 'Pixel' is different, but the rest should be very 
similar.
Take it as example.

usable example but please fix this:

- gated clock with 25 MHz

- gated clock with 5 Hz out of gates clock

- buttons sampled only every 200 ms, so possibly don't detect a short 
press

- incoming button pins directly used on logic

- extremly long logic path for pixel position check:

if(VSyncCounter < 480  ) and ( HSyncCounter < 640) and (VSyncCounter >= 
POSY0) and (VSyncCounter  < POSY1) and (HSyncCounter >= POSX0) and 
(HSyncCounter  < POSX1)

-> 60 Bits compared + Mux afterwards.

Thanks for all the replies! =)
I've managed to get a pixel on the screen now and it moves over the 
screen with the help of the buttons, there is just one remaining 
problem. The pixel moves way to fast when i push a button. The 
vga-screen that I'm using works with 25MHZ,so when I press a button, the 
pixel "transforms" into a line.
I need to decrease the moving speed of the pixel, but yet again, I have 
no idea how to do that.

I have posted my code in .vhd

I tested your construction but there was no indication on when the blank 
and v_sync signals should go low, so nothing happend on the screen.
As i said before I'm really new at this so there are a lot of codes that 
i do not understand, but thanks for the example.
I attached a syncsignal picture.
My teacher told me that i needed all the 4 signals for the screen to 
work properly.

I'm far to new at this to know how to make those changes, dont even know 
where to start

In which part of my code am I supposed to put in your code?
Also, does this mean?  "if (HZ_KeyCounter = 500000) then" the 500000, 
what does it do?
