Re: [lcd4linux] Evaluating conditional expression on strings

[Michael R. <mi...@re...>]

Well, this is probably years ago, but... but... but...

lcd4linux now supports alphanumeric operators, and there are string
operators like 'eq', 'ne', 'gt', ....

it was easy... (as it#s always easy as soon a you think twice about it)

Ok, here's your problem:

>    }

You are not allowed to use 'special' widgets (like timers) in a
Row/Column fashion. That's what the message 'Class not applicable' means.

This config works for me:

Layout Default {
   Row1 {
     #Col1 'READFLAG'
     Col2 'TEST'
   }
   Timer1 'READFLAG'
}

Re: [lcd4linux] [LCD4LINUX]Timer in SVN problem

[yvecai <yv...@gm...>]

Ok,"widget 'READFLAG': class 'Timer' not applicable" happens when I 
place the 'Timer' widget in a layout like in the following lcd4linux.conf.
And I did this to try to understand why my variable 'flag' is not 
assigned by this widget.

My wish here would be to write '4' on the screen.

Here is my lcd4linux.conf :

Could you please provide your lcd4linux.conf as a whole?

I suppose you're using the same widget name twice; using two different
classes.

Well, you're suffering from the "Portishead syndrome" :-)

just add "asc255bug 1" to the config file, and you'll be fine!

I'm afraid there won't be a short-term solution to this.

There are two possible solutions to your problem:

- the iconv plugin (documented in the wiki)

- the \octal notation if you want to add some fixed ASCII codes to the
display (eg the degree symbol)

Thanks for the info. I got the same problem. A simple "touch
config.rpath" solves the problem for me. But I found a (hopefully)
generic config.rpath (seems to be related to gettext) and added it to
the repository.

So it should be fixed in SVN.

My display is exactly two pixels wider than the 21 chars that fit into one

Yea, that's right. th "Icons 8" statement tells lcd4linux to reserve all
8 user-defineable chars for Icons, leaving exactly none to the bar
processor.

No again. lcd4linux creates widgets only if it finds them in a "Layout"
Section

Of course it's possible, as long as a) your display supports the degree
char, and b) you can find out which ascii code it uses. If it's a
strange ascii value, you can always use the \octal notation.

Hi Michael,

thanks for your prompt help. - However, for some reason your answer got
plonked as spam and today I found it just by chance while browsing the
online-archives ...

What I did: I threw everyting not neccessarily needed out of my
lcd4linux.conf. Now I don't have any errors. - That's good.

However, to understand the Problem, here's the initial situation:

In my lcd4linux.conf I had set "Icons 8", defined all the sample icons
and bar-widgets from the sampe-config but used only two Icons ("Rain"
and "Blob") and a split horizontal bar (BusyBar).

Now, what exactly causes the problem? If I get you right, this must be
(a) - that I had set "icons 8" and used a bar on top

Or could it be alternativle also
(b) - that I had defined icons that were not needed
(c) - that I had defined many bar-widgets I were not using
because the bare existence of these definitions in the config file uses
the resources, even if they are not displayed in the screen-definition?

By the way: Is there a possibility to get my display to show the "°"
symbol  as such, when it's part of a displayed text (I read 
temperatures from a file, so that I want "xx.x °C").

Thanks a lot

Stefan.

Hi Stefan,

> What is here the problem? 

I suppose you're using a lot of different bars, maybe double bars.

A HD44780 display has only 8 user-defineable characters, and it is not
possible to map every combination of (double-)bars to this 8 chars.
lcd4linux tries to be very clever in finding a way to display your bars
with the available chars, but if the situation gets too complex it may
fail. This is what this message is about.

Hint #1: don't mix horizontal and vertical bars.
Hint #2: dont mix E(east) and W(west) bars

If this does not help, please post your full lcd4linux.conf

No, I'm afraid there is none. Maybe you can tweak your syslogd to not
write these messages to /var/log/syslog or whatever.

the fuzz values influences timings on the parallel port, and has nothing

Hi there,

I'm running lcd4linux on debian etch (0.10.0+cvs20060825-1) with a

supposed to (means: the bars and widgets work as wanted), but I get
(despite correct operation) tons of error-messages logged in my syslog:

What is here the problem? - Or alternatively: Is there a simple way to
prevent lcd4linux from logging to syslog?

My config is as follows (I played a bit with the "fuzz"-value in order
to solve this, but so far with no result:

    # generic HD44780 display (LCD4Linux wiring)
    Display HD44780-generic {
        Driver 'HD44780'

        }
        Timing {
            fuzz '85'
        }
    }

When starting lcd4linux I tried using multiple "-q" options (see

    #! /bin/sh

    DAEMON=/usr/sbin/lcd4linux
    DAEMON_OPTS="-qqq"

    test -x $DAEMON || exit 0
    test -f /etc/lcd4linux.conf || exit 0

    set -e

    case "$1" in
      start)
            echo -n "Starting $DESC: "
            chmod 600 /etc/lcd4linux.conf
            start-stop-daemon --start --quiet --pidfile
    /var/run/$NAME.pid \
                    --exec $DAEMON -- $DAEMON_OPTS
            echo "$NAME."
            ;;

Any idea how to prevent this log-overflow would be highly aprreciated.

[lcd4linux] New LCD Display

[Eric <er...@gm...>]

I have a new LCD display from MatrixOrbital (LKL202-25-USB-WB). They
recently updated this LCD to include a European display set instead of
a Japanese one. This means that instead of sending code 0xFF to the
display for a solid block, a custom character is needed. If you do
send 0xFF, you get an inverted P instead. I cannot change this on the
hardware and was wondering how I might do this in the source code...
Since the bar widget expects to send a character (255) I can't figure
out how to change it to a custom character that will display a full
block instead of a "P".

Also, I've looked at "virtual rows". Will this be implemented soon?
lcdproc does not work for me on this display, but lcd4linux does and
this is the one feature I am missing.

Thank you all for your support.

Just realized I sent my reply directly to Michael instead of the list...

Hello,

testserdisp doesn't really help either, something must be wrong there. O.o

root@d-wwow:/home/marcel# testserdisp -n "CTINCLUD" -p "07c0:1501" -d 2

[lcd4linux] Dallas 1 wire temp on Matrix Orbital

[Toby M. <to...@di...>]

Hi,

Just wondering if someone can help me, is it possible to get the  
Dallas 1 wire temperature readings using the matrix orbital driver? (I  
have a MX222)

I see looking on the wiki there is a closed ticket related to this :

http://ssl.bulix.org/projects/lcd4linux/ticket/80

but it does not really specify how to do it?

thanks
Toby

There is a little test program that comes with serdisplib (called
'testserdisplib' or something...) Try if this one works.


HTH, Michael

[lcd4linux] serdisplib fails opening an usb display without error message

[Marcel <ta...@gm...>]

Hello!

I can't get lcd4linux open my usb display. Just compiled the svn source with 
serdisplib support (which is also handmade with libusb-support...), but 
lcd4linux just produces this:

marcel@d-wwow:~/Desktop/lcd4linux$  
sudo ./lcd4linux -Fvv -f /home/marcel/lcd4tanu.conf
Version 0.10.2-SVN-796 starting
[KVV] Using station 89
[KVV] Using default port 80
[KVV] Using default refresh interval of 60 seconds
[KVV] Default abbreviation setting: off
lcd4linux.c: initializing driver serdisplib
serdisplib: $Rev: 840 $
serdisplib: header  version 1.97
serdisplib: library version 1.97
serdisplib: open(07c0:1501) failed:

The usb device id is definitely correct:
marcel@d-wwow:~/Desktop/lcd4linux$ sudo lsusb
Bus 004 Device 003: ID 07c0:1501 Code Mercenaries Hard- und Software GmbH

I've also tried the X11 driver for testing which was successful, so there must 
be something wrong with serdisplib I think. But where may I start?

[lcd4linux] Multiple Screens

[Toby M. <to...@di...>]

Hi,

Looking through the archive, This seems to have been asked a few times  
in the past. I have a smallish display (2x20) so i would like to have  
one one screen of information shown for a few seconds, then another  
screen displayed, etc.

I undestand from the manual this could be done with virtual rows in v  
0.9 but not in the most recent version,

as explained in the manual :
---------------------
At the moment this window is fixed in the top left corner, but it will  
be moveable in the future (to achieve something similar to the virtual  
rows in LCD4Linux-0.9).
---------------------

Is is possible to do this in the most recent version or do you advise  
me to use the older version 0.9 for now?

thanks
Toby
