Hi,
first i'm sorry for my poor English but I'll try to describe the problems as
well as I can.
Yesterday I got my 20x2 display working with LCDProc (installed it via
apt-get).
Sometimes it works quite fine but sometimes I get this problem: Garbage is
displayed on the display (especially in the first line) which makes it
unreadable. I set DelayMult to 4 as it was described here:
http://tuxgraphics.org/electronics/200504/article375.shtml. (my display is
the same - I built it after this tutorial)
And there's another thing which always happens and I think this is not
normal: The writing cursor (or whatever it is) runs and flickers over the
screen - I made a short video of it (maybe It helps to understand that
better): http://www.zippyvideos.com/7107821286494446/mvi_0295/
Any ideas?
Thank you in advance,
Martin
