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!!! 🙂

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