i have been following this list for a while, and also (unsuccessfully)
playing with HD44780 lcd's.

I finally got some time and wired up my 20x4 HD44780 according to the
diagram on the website (, but i can't get the damned
thing to work!

Its running in linux 2.2.14 (redhat 6.2), and everything seemed to compile
fine and run fine. BTW, i complied 0.4.1

Anyways, it flickers intermitently, and at one point i had a bunch of
garbage on the screen (garbage characters though), but i can't repeat that.
I've run

LCDd -t 20x4 -d HD44780 "-p 0x378 -c winamp"
LCDd -t 20x4 -d HD44780 "-p 0x378 -c bit"
and telneted to port 13666 to try to send it commands, but no.
the lcdproc client also seems to to nothing.

WHat am i doing wrong?
