Notes on this usb bus-powered 7-in LCD.
Ubuntu 9.10 has built in drivers for it (udlfb.ko) and creates a /dev/fb0 device node.
(Drive is in drivers/staging/udlfb/
To draw to the screen:
sudo apt-get install libdirectfb-bin # needed for mkdfiff utility
mkdfiff -f RGB16 <(convert -resize 800x480! novembersnow1920.jpg png:fd:1 ) | dd of=/dev/fb0 bs=1 skip=24
There is a flickering issue under linux that supposedly doesn't happen under windows that I have not investigated.
(There's an X driver for it for usage as an actual monitor but raw framebuffer access is easier at this point.)
