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.

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.
