You could either post your questions here on the mailing list, or take a
look at the LEDMatrix homepage, there's an email adress at the right bottom.

No, I don't think I will implement it this way. What you're talking
about is already there, but it's called 'layers'.

Changing the layout will require the current layout to be destroyed (and
destroying all widgets, too) and create the new layout from scratch.

I'm afraid this is not yet possible. But I'm working on the "virtual
rows" stuff. At the moment there's a generic Layout-to-display transfer
function, but there's no way to modify it. I'm thinking about a plugin
that will handle this.

It will work the following way: You can have a layout larger than your
display (e.g. 6 rows for a 4x20 displays), and you can somehow "scroll"
some of the rows.

so stay tuned!

As Steve already wrote, the time plugin uses the strftime C funktion,
you'll find a complete documentation of all tokens in the strftime man page.

For your convience, I've added the relevant stuff from the manpage to
the wiki.

I think it's a misconfiguration. If your Display is in SingleScan or
DualScan mode is controlled by hardwiring a pin of the T6963. This is
done by the display manufacturer. LCD4Linux has to know about this
setting, therefore you have to specify it in the config file.

[lcd4linux] Probelms with de-installation

[Steve-Kai V. <st...@vy...>]

Hi everybody.

I fond a major Problem when you try to deinstall lcd4linux on an debian 
system.

What happened: I have one Desktop and one Server running. The Server is build 
in my desk so it is not so easy to access the Connectors at the back-side.

For testing prupose I installed my lcd on my desktop and played with  it, 
untill it works fine.

No I installed the lcd on my server, using the configuration from my desktop. 
Because this works fine i tried to deinstall it on my desktop and here comes 
the troble

apt oder dpkg whatever you do says that there was an error in the pre-removal 
script and therefor it don't do anything.

The Problem was, that befor uninstall the system sends an stop signal to the 
system, that whout be no problem, whe I would not have reboot the system 
meanwhile....

The reason is, that because there was nothing connected to the paraport devpp 
was not loaded and /dev/paraportx does not exist anymore.

and here comes the bug. lcd4linux doesn't recognise this and says that the 
driver ist not responding and sends back exit1

so the only posibility was to reconnect the lcd, modprobe ppdev and than 
(reconise that lcd4linux still was not running) uninstall it.

I don't really know if this is an program from debian or from lcd4linux but I 
thought that it should be mentioned :-)

The function for time is nothing programmt directly for lcd but it is the C 
Time Function.

check out man date there is described what the letters mean.

Hope this helps you

[lcd4linux] Automatic Switch to xmms screen

[Peter A. <pe...@le...>]

Hi,
Thanks for a great lcd software! I have just started playing with it and
have two questions that hopefully you guys can answer.
First of all, is there a way to switch to a xmms screen when you start
xmms and switch back once you have shutdown the program?

Secondly, are there any way to replace the output of the time plugin. For
instance to replace "Sat" with "Saturday" and/or the month "8" to
"August"?

Any help would be greatly appreciated.
Thanks!

No no, the problem is, that first I need 4 Lines, and as said it solves  only

Writing and reading a one line file is taking up significant CPU ?

jup I have done this by now, but 2 Problems:
1. it takes extra CPU for creating the file (which has to be done erver xxx 
Seconds to be uptodate) and you can not change the class i.E from text -> bar

You could accomplish this with a combination of the update
command and the file::readline expression recently added to
CVS.  For the line(s) that need to display dynamic
information, setup a script to write that information to a
file when the state changes (incoming call), and then have
the file::readline pull that information periodically (like
100 ms)

Widget dynamicline1 {
    class 'Text'
    expression file::readline('/tmp/somefile_updated_on_call_state_change',1)
    update 100
}

A more elegant solution would be to allow dynamic Layout
changes triggered by timers and other plugin specific
callbacks, but that isn't implemented yet.

[lcd4linux] timer-Widget

[Steve-Kai V. <st...@vy...>]

Hallo again,

Since my LCD is now working (thanks to Michael), I now have a new Probel. I 
want the LCD-display to show different stuff according to some parameters.

I.E.Normaly the display should show:

Row1: Time / Uptime
Row2: Ram / CPU
Row3: DiscSpace
Row4: i don't know :-) something

If an ISDN-Call is now comming in, the display should change to

Row1: Time / Uptime
Row2: CH1 Incomming net phone
Row3: Throughput ISDN
Row4: i don't know :-) something

My first Idea was to write serveral cascades using the Evaluator but this is 
very confusing.

The second Idea was to use the timer-widget, but an the hole page there is no 
example how this thing works, and what it does. The onlything i fond is, that 
it was placed under the Layout section and that there must be a widget xxxx 
with the name to call, but how can I place it or how it realy wors is not 
described (either in german or in english).

Is the timer-widget the thing I am searching for, or is there another way to 
solve my idea?

BTW: Is there somewhere discribed, if anybody is writing an plugin? I'm 
thinking of writing one to check if there are SMB or NFS connects on the 
System and to display them, but I have nerer used C befor, so it will be lot 
of trial and error to see how it works :-)

There's a enhanced T6963 driver available in CVS. Note the two new
parameters "DualScan" and "Cell" (documented in the wiki). Maybe you'll
have to play with them.

Looking forward to get some test feedback from you!

well, this explains some things... the debian package is *not* up to
date. Looks like the readline plugin did make it into CVS after the
debian package was built.

You have to use the CVS version and compile yourself... How to do this
should be explained well in the wiki. If you have any problems, feel
free to ask!

Works fine here....

eval> file::readline('/var/log/messages', 42)
'Aug 13 00:10:32 merlin dhclient: No working leases in persistent
database - sle'


maybe it's a typo, cause you're asking for the file..readline plugin
(it's called file::readline)

Hmmm... IIRC a large T6963 display is divided into two parts, a upper
and lowar half. The driver sets up the address ranges for both parts, so
maybe here's a bug.

Have you got a detailed description of your display, or even better, a
datasheet?

The good news is that I bought a T6963 240x128 display the day before
yesterday (there's a nice one avaliable at
http://www.neuhold-elektronik.at for 20=80). So I've got such a display
again for testing. But this may take a few days, as I've to solder a
interface first.

This means that lcd4linux doesn't get an answer from the busy-flag
check, and turns off bidirectional communication with the display,
falling back to unidirectional.

That's strange... what's the difference between the two machines?
Probably one of them having a newer parport running at 3.3V instead of 5V?

Are you sure you're using the right parport?
