[Lcdproc] Pertelian HD44780 USB

Hi guys
I know support for my Pertelian 20x4 HD44780 USB lcd display was built into
lcdproc 0.5.1,
as I previously had it working. lcdproc 0.5.2 has been built into Knoppmyth, the
system I am using
it on, and I copied in my previous LCDd.conf into the relevant place, but not
getting any output on it
whatsoever. The relevant part of my LCDd.conf is below. Please advise if it is
correct.......
[hd44780]
ConnectionType=winamp
Port=/dev/ttyUSB0
Device=/dev/ttyUSB0
Speed=0
Keypad=no
Contrast=0
Backlight=yes
OutputPort=no
Size=20x4
Charmap=hd44780_default
DelayBus=true
KeyMatrix_4_1=Enter
KeyMatrix_4_2=Up
KeyMatrix_4_3=Down
KeyMatrix_4_4=Escape
All the best,
Matt Shaw

Hi all,
Made some fixes/changes to the NoritakeVFD driver.
I have attached a diff to lcdproc-0.5.2

Yes, I did try. The scrolling problem is the same and the top two lines are
shown incorrectly. So 'ext. mode' looks like a wrong option.
I think I tried every combination of options available. The problem is somewhere
else. It could be the new timing system (dynticks) of 2.6.21+ kernels or my
current display with out-of-spec (too large) delay when changing the active
screen (EN1 -> EN2). Wiring is Ok. The LCDd's welcome screen is displayed
correctly. But fast moving info (heartbeat?) makes *bottom part of* display
SCROLL. How's that? I don't have an idea :)
May be try really SHORT (4 inch) wires to check if wiring is the problem...
