[lcd4linux] Program crashes Zire72

[Alexander G. <hag...@ad...>]

I cannot get lcd4linux to run properly. With the config somewhat nailed
down, running lcd4linux -Fvvq displays:

$ lcd4linux -Fvvq

lcd4linux.c: starting main loop


And my Palm crashes with a fatal error: fatal exception, which then
needs to be rebooted.

dmesg | grep usb yields that the palm takes /dev/ttyUSB0
and /dev/ttyUSB1 on bootup, and following each subsequent crash, takes
the next 2 numbers. ie usb2 and 3, usb4 and 5, etc.

On the palm I'm running PalmOrb 1.1a4, which works in windows using
lcdsmartie.

Any help is appreciated.

[lcd4linux] lcd4Linux:Change 2 Row every 10 Sec.

[Alexander B. <Al...@Bi...>]

Hi,

Is it possible to change the second row ervery 10 seconds, to get more
information on the second row display?

For Example like:
Layout L20x2 {
	Row1.Col1  'Info'
	Time1 {
		Row2.Col1  'ImonDSLRate_In'
		Row2.Col10 'ImonDSLRate_Out'
	}
	Time2 {
		Row2.Col1  'ImonDSLQuantity_In'
		Row2.Col10 'ImonDSLQuantity_Out'
	}
	Time3 {
		Row2.Col1  'CPU'
		Row2.Col10 'RAM'
	}
	Change 10000
}

[lcd4linux] can't "make" the lcd4linux with LUIse Driver from the CVS

[<ma...@pi...>]

Hi,

I have a Problem with the Wallbraun Electronics LCD. I bought it some month 
ago. Since there it works, after i get the CVS Version. But now the Prog 
wouldn't start. Maybe a system update could be the reason. The error msg:

$ sudo lcd4linux -Fv
Version 0.10.1-CVS starting
drv_init(LUIse) failed: no such driver

My System:
Ubuntu Dapper
gcc, automake... installed
the libluise (32bit) installed (from the package from Wallbraun HP)
 (in /usr/local/lib/libluise.so.0.1.1 and a link /usr/lib/libluise.so)

Now i would compile a new Version from CVS yesterday but i fails with:

$ make

Can anyone tell me what i can do now?

You should be able to kill this "lcd4linux zombies" (they are no real
zombies)

Thanks for pointing this out. I'll have a look at this.

[lcd4linux] Killing lcd4linux leaves it alive in the background

[Juho J. <juh...@pp...>]

Is this a known problem or am I doing something wrong:

I decided to try to make a script to switch between my different display 
layouts by first killing the running lcd4linux process using killall or 
killall -HUP commands, then modifying the lcd4linux.conf for my second layout 
and starting a new lcd4linux process. In principle it works, but then I 
noticed that the killed lcd4linux processes were actually alive! Indeed, they 
were ghosting in my system all the time... 
	I had a widget running my own script using the exec plugin. If I killed 
lcd4linux processes my script file was still constantly being executed. Even 
if I had no lcd4linux processes listed when I typed lcd4linux. Another thing 
that tells me that the system is still running lcd4linux processes is that 
when I kill and restart lcd4linux many times I end up having a very high CPU 
usage in my system. I have found no other cure for that than rebooting the 
system.
	Is this behaviour of lcd4linux a bug or should I do something differently 
when ending an active lcd4linux process? When I have more time I try to 
figure out if this is a problem in lcd4linux in general or could it be the 
exec plugin only. I am using Suse 10.0 and the latest RPM version of 
lcd4linux.

[lcd4linux] Keypad support for LCM-162

[Pete P. <pet...@sa...>]

Hi all!

I've been experimenting with LCD4linux on a Nexcom box and am
having great sucess with the display. The only thing I can't get to
work is the keypad.

Is the LCM-162 keypad supported?

Many thanks,

[lcd4linux] LCD4linux on NSLU2

[Vincent P. <vp...@fr...>]

Hi all,
 
I'am trying to play with lcd4linux and my LCD HD44780 20x4 on my
OpenSlug 2.7 Linksys NSLU2 (http://www.nslu2-linux.org/).
I'am not using the same circuit as described here :
http://chezphil.org/slugterm/
I'am using a cheap USB to // converter with USS720 Lucent chip.
This chip is supported by Linux and the driver is available in the
kernel source tree (drivers/usb/misc/uss720.c).
 
As I didn't find much info on the net about uss720 and LCD (only here :
http://www.g-cipher.net/~reboots/projects/lcd/index.html) , I'll first
sum up my successful experience using this chip on my Gentoo PC, and
then ask my question about the NSLU2 port right after :-)
 
Hardware :
PIII/600 PC running Gentoo
 
I bought a cheap USB to // converted using a USS720 Lucent chip (USS720E
is marked on the chip). The converter model is Infowave USP-1284
(Infowave Wireless Messaging Inc. P/N 901-0030) But other model use this
chip (see here :
http://www.g-cipher.net/~reboots/projects/lcd/index.html).
I've connected my HD44780 generic LCD (16 pins) to the centronic plug
following the winamp wiring.
 
Software :
 
First, you must activate support for USS720 and PPDEV in you kernel. I
selected them as Modules.
 
Rem : Parallel port should be already activated on your PC.
 
In Kernel configuration menu select :
 
<*> Parallel port support 
[*] IEEE 1284 transfer modes (don't know if it's mandatory or not)
 
<M> Support for user-space parallel port device drivers
 
<M> USS720 parport driver
 
Recompile, install new kernel (if necessary) and modules, reboot.
 
Plug the adaptor to USB
 
If you use module as me, you need to :
modprobe ppdev
modprobe uss720
 
You should have with dmesg :
[.]
ppdev: user-space parallel port driver
lp1: using parport1 (polling).
usbcore: registered new driver uss720
drivers/usb/misc/uss720.c: v0.6:USB Parport Cable driver for Cables

drivers/usb/misc/uss720.c: If you just want to connect to a printer, use
usblp insteadDisplay 
 
LCD4linux conf :
 
I use the following configuration :
 
HD44780-20x4 {
    Driver 'HD44780'
    Model 'Generic'
    Port '/dev/parport1'
    Bits '8'
    Size '20x4'
    Wire {
        RW        'AUTOFD'
        RS        'INIT'

        ENABLE2   'GND'
        BACKLIGHT 'GND'
        GPO       'GND'
    }
}
 
then : lcd4linux -Fvv
 
So, in my case, everything fine, the welcome message is displayed and
the test messages are shown.
 
Ok. Now I want do to the same on my NSLU2.
 
I configure the kernel to support parallel port. Compiled uss720.ko,
parport.ko and
ppdev.ko
After registered the uss720 and parport modules and plugged the
converter I get :

And I get a /dev/parport0 device.
 
I'v tried to compile LCD4linux but get an error about rep_nop in

As this fct is only for x86 and my slug run an Intel Xscale, I've
commented out the line. 
Even if lcd4linux compiled fine then it's not running ok .

But nothing on the LCD :-( .....
 
Here is my questions :
Does some one compile lcd4linux on armeb platform ?
Is rep_nop mandatory ? I've seen that some people provide a patch for
other arch but can't find for armed.
Is lcd4linux big-endian/little-endian dependent ? As the NSLU2 is big
endian I was wondering .
I've also seen that uss720.c is v6 on my PC and v5 on my NSLU2, does
some one have experience with this 
driver (I know it's not the good mailing list for this question) ?
 
Thanks for your help,
Best regards,
Vincent.

All I need is a copy of the the CVS root -the one stored server side-
so I can keep the history. If the history does not matter, you can
just push your files into the already-existing lcd4linux repository on

[lcd4linux] CVS, SVN, Wiki

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

Hi there,

Looks like SF is facing lots of problems with their CVS servers these
days...

I think it's time to migrate to Trac's SVN. I really like this, because
you see code changes the same way as wiki changes, using the "timeline"
function of the wiki.

I've to talk to Sam how to migrate a whole SF CVS tree (including all
the history) to Trac/SVN.

As soon as we're on SVN, there will be a rename of several files. I
don't like the "drv_generic_parallel..." anymore. I'd like to call them
"bus_parallel_" or the like..

Second, there's a problem with the wiki at the moment. At least I cannot
edit pages anymore, regardless being logged in or not. But I'm shure Sam
will fix this in the next couple of days.. (@wolfgang: That's the reason
why I did not replace the "preview" link to your pages... I simply can
not :-)

Hello, Michael!

I have been making that mistake, I've noticed.  Boy, I feel smart!  But I 
still get the segfault.  -Fvv garbles the screen, or blanks it, and then 
segfaults.  Same with just -F, or just -vv.  No options will sometimes blank 
it, or someitimes display "L4Linux", without segfaulting...but the proccess 
list doesn't show it...very strange!  Thanks for the reply, and any help is 
appreciated!

[lcd4linux] G-15 Driver segfaults, -w non-existant

[Benjamin K. <bk...@em...>]

Hi.

I'm trying to use the G-15 driver, as described here:
http://ssl.bulix.org/projects/lcd4linux/wiki/G-15

I compiled from CVS, and running lcd4linux sometimes clears the lcd, and
sometimes it garbles the default Logitech logo, but it doesn't display
what is defined in the configuration.  Always, after launching it, it
segfaults after maybe 5 seconds...-Fvv doesn't reveal any errors.

I tried with a '-w' option, as described on the above page, but
lcd4linux tells me that no such option exists...
I'd appreciate any help in getting this working.  Thanks!

I'm running two displays like this on one server in such a
fashion, specifying separate configuration files for each.
I haven't noticed any problems.

Although I am thinking of a patch to allow multiple display
setups in one configuration file under one lcd4linux process.
I think this would break fewer distro-specific startup
scripts than the multiple-config / multiple-process setup.

[lcd4linux] lcd4linux stops updating lcd

[Roland H. <ro...@gm...>]

Hello!

I have a Hitachi glcd from Wallbraun Electronics with the
luise-driver. It works but lcd4linux stops updating the
lcd after different times running. After approx. 1h 10m
updating has stopped, lcd4linux continue updating the lcd.
The time between 2 stops is different. But the approx 1h 10m
is always the same.

I'm using debian with kernel 2.6.12 and the following plugins:

- /proc/cpuinfo plugin
- /proc/diskstats plugin
- exec (external command) plugin
- I2C sensors plugin
- ISDN Monitor plugin
- /proc/meminfo plugin
- /proc/stat plugin
- statfs plugin
- Time plugin
- uname plugin
- uptime plugin

I have disabled ISDN monitor and exec plugin. The result was
the same. What can I do to point out where lcd4linux has
problems?

[lcd4linux] Starting several instances of lcd4linux

[Roland H. <ro...@gm...>]

Hello!

I have 2 lcds connected to my server. The first is a HD44780
compatible 4x20 lcd connected through the parport.
The second is a Hitachi glcd from Wallbraun Electronic connected
through usb.

At the moment starting lcd4linux twice doesn't work because lcd4linux
checks for lcd4linux.pid in /var/run. Ok, I have changed the filename in
lcd4linux.c and have compiled it again. Now I can start lcd4linux a
second time. Both lcds are working now.

Is this a common method or can I expect strange behaviours?

[lcd4linux] LCD recommendations?

[Clay B. <cla...@gm...>]

I'm looking into building a much more extensive display than I can fit 
on my 4x20 one that I'm emulating on my Palm.

What would everyone suggest for the largest (preferably 8x[something 
bigger than 19]) display that is <$100, supported by LCD4Linux, and 
reasonably easily acquired (links to sellers HIGHLY appreciated).


Also, button support is a plus, but it's less important than size.

[lcd4linux] Lcd4Linux and ubuntu

[<for...@gm...>]

Everything seems to be fine, but when I run lcd4linux, nothing happens on m=
y
40x2 display (A few LED's on the test ciruit are lit up, but do nothing).
Here's what I've got for my config:

Display HD44780-40x2 {
    Driver  'HD44780'
    Model   'generic'
    #UseBusy  1
    Port    '/dev/parport0'
    Size    '40x2'
    Wire {
        RW      'AUTOFD'
        RS      'INIT'
        ENABLE  'STROBE'
        ENABLE2 'GND'
        GPO     'GND'
    }
}

Widget CPU {
    class      'Text'
    expression  uname('machine')
    prefix     'CPU '
    width       9
    align      'L'
    update      tick
}

Layout Default {
    Row1 {
        Col1 'CPU'
    }
}

Variables {
   tick 500
}

Display 'HD44780-40x2'
Layout  'Default'

Here's the output of lsmod:
$ lsmod | grep parport
parport_pc             31812  2
parport                32072  3 ppdev,parport_pc,lp

I tried running lcd4linux a few times:
$ sudo lcd4linux -Fvv
Version 0.10.1-CVS starting
plugin_cfg.c: Variable tick =3D '500' (500)
lcd4linux.c: initializing driver HD44780
HD44780: using model 'generic'
HD44780: using parallel port
HD44780: using 1 Controller(s)
HD44780: using 8 bit mode
udelay: CPU supports Time Stamp Counter
udelay: CPU runs at 599.660000 MHz
udelay: using TSC delay loop, 600 ticks per microsecond
HD44780: using ppdev /dev/parport0

After nothing happened on the display, and ther terminal sat at that last
line, I killed it and checked dmesg, finding this repeated a few times:
[4309928.636000] ppdev0: registered pardevice
[4309982.517000] ppdev0: unregistered pardevice

Any more ideas? I've also tried using a raw port (0x3bc) without any luck.
Thanks.

As I got rid of my Palm when switching to BlackBerry, I cannot test it.

What does 'lcd4linux -Fvv' say?

Well, this won't work, because the Driver 'USBLCD' is a very different
driver. Try using one of the MatrixOrbital Models that are supported by
PalmOrb. I think there schould be a sample config in the wiki.
