Arduino Due VGA Signal Out

Photo credit: [Stimmer] on the Arduino Forum
[Stimmer] on the Arduino Forum hardcoded a way to display 160×240 (320×240 after some posts) VGA signal.
After working out how to do a timer interrupt I’ve had a go at making a VGA framebuffer. It is rather low-res at present(160×240) and fuzzy but I hope to be able to improve that. It has 8-bit colour (RRRGGGBB).
I cannot get Eagle to run right now so will have to describe the schematic in text:
Due pin 2 -> VGA pin 13 (HSync)
Due pin 3 -> VGA pin 14 (VSync)Due pin 25 -> 820R resistor -> VGA pin 3 (blue)
Due pin 26 -> 390R resistor -> VGA pin 3 (blue)Due pin 27 -> 2k2 resistor -> VGA pin 2 (green)
Due pin 28 -> 1k resistor -> VGA pin 2 (green)
Due pin 14 -> 470R resistor -> VGA pin 2 (green)Due pin 15 -> 2k2 resistor -> VGA pin 1 (red)
Due pin 29 -> 1k resistor -> VGA pin 1 (red)
Due pin 11 -> 470R resistor -> VGA pin 1(red)Due pin GND -> VGA pins 5,6,7,8,10

wow, this is great. but what is the source code to use to achieve that?

forget it, it’s in the forum.
I must say it’s brilliant!

Wow this is totally retro. I remember doing this kind of thing on a 386 something like 15 years ago! I can’t wait to get mine.
