It's been a fun project to work on so far, and my first Verilog program...

I originally used an AD724 RGB to NTSC chip tp create the NTSC color signal, but decided I don't want to rely on a custom IC so now everything is done in code. All that comes out of that Spartan is the external SRAM lines and a few resistors!

Cheers,

Did I mention that FPGAs are fun?
Looks pretty cool.

Thanks!

I agree, Verilog and VHDL is a language that compares to basic for complexity, yet offers so much power when running on a CPLD or FPGA.

I still only know the basics, and have yet to try a test bench or simulation, but I sure did get a lot done on my video project in a short while.

Thanks again for putting up this site - it has great information!

Awesome.

I'm planning on starting with the same thing. I just got VGA going (my first project) at different resolutions and such. My next step is the ddr2 ram on the board. I've been studying the timing for about a week now.

Hey thanks!
I remember spending time on your site.... I really enjoyed BMOW!

If anyone doing a similar project wants to share ideas, shoot me an email!

Would you happen to have any good resources explaining how to construct the composite video signal with color from a RGB framebuffer?
