A project log for A VGA Display for the Intel Edison!

I did this with the Intel Edison Arduino Breakout Board. I assume it is possible using other methods, but I can't comment from experience.

As for a display, I'd love if you tried my VGATonic VGA SPI video card, my entry to the 2015 Hackaday Prize. The feature I'm taking advantage of is the minimal (like, 2/307202 %) overhead SPI framebuffer.

Everything you need to build VGATonic can be found on that page or in the Github repo.

There is no reason why you can't do it with notro's excellent FBTFT as well.

25 MHz SPI at 5v on the Arduino breakout with this setup is rough: my jumpers are 8 inches or so long, and you're looking at about 3 connectors and another 3-4 inches between silicon. So, twist your SPI wires up with +5v and Gnd (I use Gnd with Chip Select - that is the most sensitive) to protect your signals as best you can (or use shorter/better wire!):

That's the standard pins for MOSI and SCK (11 and 13), and a custom chip select - pin 8.
