: Got it. Is there some sort of design doc that states the goals for
: NanoGUI, how it is laid out, etc?
Not yet. Inspection of mwin/src/drivers/scr_bogl.c, the linux
framebuffer driver, is quite straightforward. The scr_herc.c driver is a very
basic complete driver for the PC hercules card.
I'm assuming that access to some sort of
: framebuffer is required.
No. The nano-X and Microwindows graphics model doesn't
assume anything about the graphics hardware other than it has
read and write pixel capabilities. The framebuffer architecture just hides
the hardware graphics setup and mmap()'s the video ram into user space.
We don't require it. There are currently drivers written for Linux 2.2.x framebuffer,
Linux 2.x SVGALib, ELKS 0.78, and MSDOS, and bare PC hardware.
Given that the uCSimm is designed to function
: with relatively simple LCD displays I'm not sure how well this will work
: out, but I willing to bridge any development gaps as needed.
Worry first about how to read and write a pixel, and you're 90% of the
way there.
