how do I connect a FPGA to a VGA monitor?

[carlos345]

Hi everybody

I write because I need your help:

I need to conect four VGA's screens to a FPGA, the question is

how do I connect a FPGA to a VGA monitor?
Will I need protection for the FPGA?
if yes, which circuit can use?

thank you to answer me

regards.

Hi,

Visit the following site..

DDS I had already visited this web, but here only uses three resistors

Is there a surer form?

Check the Spartan-3E development kit schematics on xilinx.com, they have an onboard SVGA connector to the Spartan-3 chip.

Hello Carlos345,

Frankly, I have never tried this application with three resistors VGA monitor driving by an FPGA. But it seems reasonable.. Should be.. At the other hand, this site is the one of best about FPGAs on the web that I think.. It worths to try.. Almost zero risk..

Regards..

the pong game on FPGA4fun uses a 3bpp (bits per pixel) vga monitor core. if you need to show an 8bpp image on the monitors you will need to design an 8bpp core and you will need an 8-bit triple DAC like the THS8134B (the XSB-300E board from XESS uses a simillar DAC).

what do you want to display on the monitors? text? graphics?

Agree with SamCheetah, it depends on ur application, if it require variety in colours than u can use 8bit or 10bit triple video DAC, just u have to take care in generation of sync signal.
