My 20x2 OLED works fine on my firend's Windows box but when I run it on my Linux machine with LCD4Linux (and lcdproc) the characters are misplaced and other "bad" characters are mixed in.
The display is supposed to be "compatible with HD44780" according to the manufactorer
http://www.fractronics.com/2x20oled.shtml
I have used this wiring
http://www.fractronics.com/lcdcontrast.gif
but I don't know it it's a 4-bit, 8-bit or Winamp. What I _do_ know is that the Winamp wiring example shown on
http://lcd4linux.sourceforge.net/display/hd44780/main.html
is the only one that lights up the dispay at all. This is my /etc/lcd4linux.conf:
# /etc/lcd4linux.conf
Display "HD44780"
Port "0x378"
Size "20x2"
# Winamp wiring
Wire.RW "AUTOFD"
Wire.RS "INIT"
Wire.ENABLE "STROBE"
Wire.GPO "GND"
row2:"hello world"
and the result from lcd4linux -Fvv:
# lcd4linux -Fvv

When I run it the display show the following:
--------------------
* LCD4Linu| 0.=.51
--------------------
which, I assume, is wrong. Anyone have an idea of what I do wrong? The display works fine without hazzle under Windows and jaLCD.
Thanks in advance!
