Great thread!

I am looking for a simple ready made solution for generating a 640x480 or 800x600 VGA synch signals from my arduino setup.

I don't need to generate RGB signals, only the sync signals.

I have a Duemilanove board that I am working with.

Can you recommend any programs to start working with (links)?  Anything that can generate a solid synch signal would be OK.  I'm interested in gutting the code if necessary.

Thanks!

BTW - some work that I have been doing with analog VGA synthesis can be found here: http://youtu.be/r1FtvA-pXFg I'm using audio feedback to drive the RGB lines on a VGA signal.  The only thing I'm missing is a good compact and integrated synch generator.

Hi pixelform!
Thanks for your comment.
Recently, I enjyoy with RC plane every weekend.
So I have not refined code an not add comment in English yet.
I uploaded the new video and code.
It's currently - temporary version.

I have used a Duemilanove board for NTSC or RGB signal generate.

H-sync signal is made with timer1
V-sync signal is made by software ( in interrupt routine )

Please check following  sources. You can downlod the code from Google code.

defTimer.h  timer1        - set data ( sorry include Japanese comment )
SYS_Ini.cpp : IniTimer( ) - initialize timer1
INT_ICF1.cpp                - interrupt function pointer table
INT_ICF1_RGB_TEST.cpp - display test mode  P_VSYNC_OFF/P_VSYNC_ON <- V-sync generate

Nice ! and I want to try.

Best regards

I HATE the fact I'm resurrecting an old post... but this project is too damn interest to let it forgotten xD.
Any news on the development? I'd thank if someone had the actual wiring diagrams. I have a Arduino Mega 2560, , but I think I could change things to make it work in this one too,. If someone has anything to help me out, I'd be really thankful.
