VGA help!!!

hi there!

during my final project i'm trying to build a sniffer (network analyzer) with the DE-2 board and niosii, i wrote a code for the sniffer and add it to the DE2_net example, now the next level that i'm stuck with is to connect it to the VGA port and show the data of the network on a screen. is there any good design for it and recommendations for the best way to combine it with the DE_2 design?

thanks a lot!!! :)

    I'd start by taking a look at the DE2-TV and DE2-VGA demos on the Terasic CD.

    10x for replying!

    i take a look at DE2-TV and assume that i connect the components of the DE2_NET with the DE2_TV. i haven't find any folder with software inside it. how i'm writing commands to the VGA controller?

    A region of memory is defined to contain the frame buffer for video data. To display you write bits to the frame buffer.

    excuse my ignorance but i still stacked with it. i just need to know which component i have to add at the qsys to the DE2_NET project for display characters on screen through vga output.

    Hello levw,

    The libraries and components in qsys (as far as i know) are basically targeted to full graphics applications.

    What you seem to need is what the first IBM pc's did (80x25 crt character mode)

    As an exercise to learn verilog, i am exactly building what you seem to need.

    I am also really interested in how you bluild your netwerk sniffer.

    Would you be interested in some collaboration ?

    Best regards,

    Johi.
