: Hi,I run nano-x and uClinux on 68VZ323ADS,but the speed of display is
: too slow, who can tell me how to speed up it from software?
Likely you will need to write an optimized screen driver
for the 4bpp or 2bpp display that you're likely running.
There has been some work in this area, but I don't have
anything I can release yet. You might check out the
src/drivers/fblin4hp.c in the current CVS for an initial
optimized implementation that writes 32 bits at a time,
rather than just a pixel at a time.

Greg
