Serial USB problem

[drakulaj]

Ahoj,
mam problem s USB <->RS232 prevodnikem od FTDI - FT232RL. Prvni problem byl, ze si ho nejdrive automaticky zabral program brlty. Po jeho odinstalovani uz vidim  /dev/ttyUSB0, ale nemohu s nim komunikovat. Minicom (i jine RS232 terminaly) s nim nemohou nic delat. Zkousel jsem to i na jinem NB se stejnou distribuci (KUBUNTU 7.10) a stejny problem. DMESG nehlasi zadny problem. Trohu se mi zda se nemam opravneni s nim komunikovat, ale ani sudo nezabralo. Nemate nekdo podobne zkusenosti?

tak ja mam s FTDI taky problem doufam ze nekdo pomuze s resenim :-) mam na tom pripojeny displej .... FT245BL

a chtel bych jej zprovoznit pod ubuntakem

muj postup ...

stahnu lcdproc z http://lcdproc.sourceforge.net/nightly/ CVS ...

$ ./configure
$ make
# make install
# apt-get install epm
$ epm -v -f native LCDproc

pak mam nastaveno podle http://lcdproc.sourceforge.net/docs/current-user.html#hd44780-howto

LCDd.conf vypada takto :

Kód: [Vybrat]

# LCDd.conf -- configuration file for the LCDproc server daemon LCDd
#
# 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]. For the menu there is
# a section called [menu]. 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 defines the
# size of the display. The default driver to use is curses.
# If the driver is specified using the -d <driver> command line option,
# the Driver= options in the config file are ignored.
#
# The drivers read their own options from the respective sections.



## Server section with all kinds of settings for the LCDd server ##
[server]

# Where can we find the driver modules ?
# IMPORTANT: Make sure to change this setting to reflect your
#            specific setup! Otherwise LCDd won't be able to find
#            the driver modules and will thus not be able to
#            function properly.
# NOTE: Always place a slash as last character !
DriverPath=/usr/local/lib/lcdproc/

# Tells the server to load the given drivers. Multiple lines can be given.
# The name of the driver is case sensitive and determines the section
# where to look for further configuration options of the specific driver
# as well as the name of the dynamic driver module to load at runtime.
# The latter one can be changed by giving af File= directive in the
# driver specific section.
#
# The following drivers are supported:
#   bayrad, CFontz, CFontz633, CFontzPacket, curses, CwLnx, ea65,
#   EyeboxOne, g15, glcdlib, glk, hd44780, icp_a106, imon, IOWarrior,
#   irman, joy, lb216, lcdm001, lcterm, lirc, lis, MD8800, ms6931, mtc_s16209x,
#   MtxOrb, mx5000, NoritakeVFD, picolcd, pyramid, sed1330, sed1520, serialPOS,
#   serialVFD, shuttleVFD, sli, stv5730, svga, t6963, text, tyan, ula200,
#   xosd

# Should we report to syslog instead of stderr ? [default: no; legal: yes, no]
#ReportToSyslog=yes

# User to run as.  LCDd will drop its root priviledges, if any,
# and run as this user instead.
User=nobody

# The server will stay in the foreground if set to true.
#Foreground=no

# Hello message: each entry represents a display line; default: builtin
#Hello="  Welcome to"
#Hello="   LCDproc!"

# GoodBye message: each entry represents a display line; default: builtin
#GoodBye="Thanks for using"
#GoodBye="   LCDproc!"

# Sets the default time in seconds to displays a screen.
WaitTime=5

# If yes, the the serverscreen will be rotated as a usual info screen. If no,
# it will be a background screen, only visible when no other screens are
# active.
#ServerScreen=no

# set master backlight setting [default: open; legal: off, open, on]
#Backlight=open

# set master heartbeat setting [default: open; legal: off, open, on]
#Heartbeat=open

# set title scrolling speed [default: 10; legal: 0-10]
#TitleSpeed=10

# The "...Key=" lines define what the server does with keypresses that
# don't go to any client.
# These are the defaults:
ToggleRotateKey=Enter
PrevScreenKey=Left
NextScreenKey=Right
#ScrollUpKey=Up
#ScrollDownKey=Down

# If you have only 4 keys, you can choose to use this:
#ToggleRotateKey=Enter
#PrevScreenKey=Up
#NextScreenKey=Down

# If you have only 3 keys, you can choose to use this:
#ToggleRotateKey=Enter
#PrevScreenKey=Up



## The menu section. The menu is an internal LCDproc client. ##
[menu]
# You can configure what keys the menu should use. Note that the MenuKey
# will be reserved exclusively, the others work in shared mode.

# The following works excellent with 4 keys or more.
MenuKey=Escape
EnterKey=Enter
UpKey=Up
DownKey=Down
# If you have 6 keys you may define these as well
#LeftKey=Left
#RightKey=Right

# If you have only 3 keys, you could use something like this:
#MenuKey=Escape
#EnterKey=Enter
#DownKey=Down
