Hello everybody...
I have an FPGA spartan 6 (sp 601) , also I need to connect it to the monitor but there is no VGA port in the board , So is there any solution for this??
also i found an mini usb_to_vga cable but what is the output to the mini usb will be ? if the vga signals are(R,G,B,vs and hs) ...

thanks in advance

 

Hi;
For VGA, if you don't need true color, then use 3 gpio as RGB lines. So that logic high on any line result a full R/G/B color.
ie GPIO[2, 1, 0] = [R, G, B] then
000 black
100 red
010 green
001 blue
101 magenta
...
111 white
But keep in mind that RGB levels are maximum 0.7V. So you need a simple resistor divider cct to adjust voltage value. You can connect VGA connector from IO expension port of dev board.
And of course H/V sync...

Hope helps
Goodluck
