Re: A82: Dead list, huh?
It is quite suprising that there are that big differences between the
different calcs. I first foud this out when I was helping Sam Davies making
a fast display routines, and it showed out that the version he wrote did not
work on all calcs. Most people probably have not noticed this, but the
routines in CrASH is actually too fast. When working on Ash 3.1 I tested one
of my Ash programs using CrASH, and if I used the build in routine it would
actually mess up the display, and doing a CLEAR_LCD did no clear the whole
display. As far as I remember, the quality of grayscale also varies form
calc to calc depending on the speed of the display controller. The best
solution would probably be to use the busy flag, but that will probably be
too slow.
