Hallo zusammen,
ich hab das Problem das ich unter Linux mit meinem hd44780 kompatiblen Display nichts angezeigt bekomme.
Linux ist ein gentoo mit 2.4.23er Kernel
Der LCDd startet ohne zu meckern, auch # /etc/init.d/lcdproc start macht er ohne zu murren. Aber anzeigen tut er nichts. Das Display funktioniert unter WinXP, also daran liegt es nicht.
Das Display ist am paralell Port angeschlossen.
hier mal die confs: (sorry für den elendlangen Text)
#LCDd.conf
#
# This file contains the configuration for the LCDd server.
#
# The format is ini-file-like. It is divided into sections that start at
# markers that look like [section]. Comments are all line-based comments,
# and are lines that start with '#' or ';'.
#
# The server has a 'central' section named [server]. Further each driver
# has a section which defines how the driver acts.
#
# The drivers are activated by specifiying them in a driver= line in the
# server section, like:
#
# Driver=curses
#
# This tells LCDd to use the curses driver. The first driver that is
# loaded and is capable of output becomes 'the' output driver.
# All extra drivers can only serve as input.
# The default driver to use is curses.
#
# The drivers can read their own options from the config file, but most of
# them don't do this yet. They expect 'command-line'-format parameters that
# were previously placed on the command line. These parameters can be
# given to the driver in the following way:
#
# Arguments="place arguments here"
#
# The arguments between the quotes are passed to the driver.
# As said before these are the same arguments that the driver would have
# been passed under the old command line format of
#
# -d <driver> "<driverargs>"
#
# Note that the -d option still works, but not allows driverargs anymore.
# If -d is specified on the command line, the Driver= options in the
# config file are ignored.
[server]
# Server section with all kinds of settings for the LCDd server
Driver=HD44780
#Driver=none
#Driver=curses
#Driver=HD44780
#Driver=lcdm001
#Driver=MtxOrb
#Driver=CFontz
#
# Tells the server to load the given drivers. Multiple lines can be given.
# NOTE: You may activate several input (input only) drivers but only ONE output
# driver, which should be the first.
Bind=192.168.123.187
# Tells the driver to bind to the given interface
Port=13666
# Listen on this specified port; defaults to 13666.
ReportLevel=2
# Sets the reporting level; defaults to 2 (warnings and errors only).
ReportToSyslog=no
# Should we report to syslog instead of stderr ? Default: no
WaitTime=5
# Sets the default time in seconds to displays a screen.
User=root
# User to run as. LCDd will drop its root priviledges,
# if any, and run as this user instead.
ServerScreen=no
# Enables the built-in server screen [Default: no]
# yes : always,
# no : when there are no other screens active.
Foreground=yes
# The server will stay in the foreground if set to true.
# Otherwise the server will fork to background and report
# to syslog
# TIP: The following options can also be modified from the
# server menu (which requires a driver that supports input)
Heartbeat=open
# The server has serveral heartbeat modes
# on Stays on all the time
# off Stays off all the time
# slash Rotating slash all the time
# open Can be controlled by all clients
InitialHeartbeat=on
# This sets the initial heartbeat state if the heartbeat mode is "open"
# Affects the server screen only
# on Heartbeat activated
# off Heartbeat disabled
# slash Heartbeat replaced with a rotating slash
Backlight=open
# The server has serveral backlight modes
# on Stays on all the time
# off Stays off all the time
# open Can be controlled by all clients
InitialBacklight=on
# This sets the initial backlight state if the backlight mode is "open"
# Affects the server screen only
BacklightBrightness=255
# This sets the backlight brightness in state "on"
# NOTE: Not all drivers/devices support setting the brightness this
# way. Some don't support switching the backlight on/off at all,
# some can switch the backlight on or off only. If the latter is
# the case BacklightBrightness must be > 0.
BacklightOffBrightness=0
# This sets the backlight brightness in state "off"
# NOTE: Not all drivers/devices support setting the brightness this
# way. Some don't support switching the backlight on/off at all,
# some can switch the backlight on or off only. If the latter is
# the case BacklightBrightness must be = 0.
