Does anyone has try vga adapter from http://www.serasidis.gr/circuits/AVR_VGA/avr_vga.htm ?

I try it but i didn't work the signal from VSYNC (PORTD.3) and RGB (PORTB.5) is drop when I connected to Monitor's VGA Connector.

Seems I have to check the code too :(

You certainly got the monochrome version here : http://www.serasidis.gr/circuits/AVR_VGA/avr_vga.htm

 

If you take a look at the following link, http://www.elektronika.lt/schematic/theme/79/7090/, you will notice that you can drive the 3 colours directly : http://en.wikipedia.org/wiki/VGA_connector

 

Pin 1 : Red

Pin 2 : Green

Pin 3 : Blue

Pin 13 : HSync

Pin 14 : VSync

 

It should't be difficult to adapt the program to support 8 colors. Check if you have enought RAM to implement the video pixel map.
