The LCD's

Started by tishamp September 24, 2003
I have experience (bad ones) with the Nokia Phone serial LCD's.It does
go black some times.That means that it is in one of the Modes where
the registers are set to all pixels on,in my case that means my
data/command pin is loose and it is interpreting data as command :).
About the dirty screen bit.When the LCD is reset it has random stuff
in the data RAM.You have to explicitly clear everything to get a blank
screen.If you get patches of dots.Your data pins are loose :)/too
fast.
It eventually works out and is heaven for debugging and writing smug
comments.
Good Luck,
Cheers,
Tisham.
