Fomu Crazy VGA Experiment

This is based on the "blink-expanded" example of fomu-workshop. The idea is to generate VGA via the 4 exposed pads of the Fomu, plus the USB GND like this:

  • Pad 1 -> VGA HS
  • Pad 2 -> VGA VS
  • Pad 3 -> VGA Color Bit 0
  • Pad 4 -> VGA Color Bit 1
  • USB GND -> GND

I also want to implement a simple framebuffer that would accept data via USB, but so far I couldn't get the random USB code that I found (usbcorev) to work. I still need to learn more about the USB low-level details. Help is appreciated!

Using

Type make to build the DFU image. Type dfu-util -D blink.dfu to load the DFU image onto the Fomu board. Type make clean to remove all the generated files.
