Re: Article: NuttX for PinePhone: LCD Panel

2022-12-28 Thread Gregory Nutt 
How would you handle the numerous color resolutions (mono, greyscale,
various 8, 16, 24,32 color formats)?  How would you handle different color
representations (RGB multiplexed, CMYK multiplexed, planar colors, etc.).
Rotations?  Interleaved pixels? If it does not work with all video
hardware, it really can't be a system solution.  See
include/nuttx/video/fb.h for a list of some color formats.

An alternative place to do this in the graphics application.  NX, for
example, already can put up the log initially and this works on all
displays.

Yep we should show our own logo! Anyone got an SVG file? I'll turn it into
the Startup Image for PinePhone :-)

Very nice Lup! Kudos!!!

I think we need a drivers/video/logo/ like the Linux kernel to display
the NuttX logo.
