At the job I had this summer I played around with a virtex-II pro and tried to
make a video controller and got something that seemed to work.
The xilinx example files had the timing numbers needed. From there:
// 800 X 600 @ 60Hz with a 40.000MHz pixel clock
`define H_ACTIVE 800 // pixels
`define H_FRONT_PORCH 40 // pixels
`define H_SYNCH 128 // pixels
`define H_BACK_PORCH 88 // pixels
`define H_TOTAL 1056// pixels
`define V_ACTIVE 600 // lines
`define V_FRONT_PORCH 1 // lines
`define V_SYNCH 4 // lines
`define V_BACK_PORCH 23 // lines
`define V_TOTAL 628 // lines
Thank you. This is exactly what I wanted.
Would the rest of the video controller be useful? Just thinking that something
simpler than the one in svn could be useful for testing.
That's the objective. Something simple. If yours is simple, we could
hack it in.
I'm just about to post a module that's a template for head zero's
video signals. Using that, you can wrap it around just about
anything.
Thanks!
