The goal of this series is to get the built-in LCD of the LEGO MINDSTORMS EV3
working. But, most of the content here is building up the infrastructure to do
that.
Some general comments/questions:
I have noticed that DRM doesn't really have support for monochrome
displays. I'm guessing that is because no one really uses them anymore?
The LEGO EV3 display is just an LCD (not the backlit kind). It has two
modes of operation. It can to 2bbp grayscale or it can do 1bpp
monochrome. The grayscale isn't the best (looks splotchy in places), so
it would be nice to be able to choose between these two modes. How would
I implement something like that?
Also, how can I indicate to userspace that this display really is
monochrome/grayscale since the reported color depth 16bpp?
