[lcd4linux] Is this list alive?

[Michelle D. <md...@oc...>]

I haven't gotten a single email...and no reply to my last one.  I just noticed that the lcd4linux software was last updated 2 years ago.

Is this project dead?  Should I move on to lcdproc or something else?

Thanks

[lcd4linux] Creating menus

[Michelle D. <md...@oc...>]

I'm new to lcd4linux and have it up and running no problem.  Just getting into designing screens.

I'm switching from LCDproc and have gotten used to rotating through screens.  Is this possible?  Can I use a widget with a timer than increases a variable (say mod 4), and then changes layout do a variable name like screen_3 (with _3 being the variable)?

Or is this really a one screen only kinda program?

Thanks!

Re: [lcd4linux] Sure LCDs

[Matt J. <mat...@gm...>]

OK, I added support to MatrixOrbital.c and it seems to work with newer
Sure LCDs.

[lcd4linux] Sure LCDs

[Matt J. <mat...@gm...>]

Hi,

I'm having a devil of a time getting a 4x20 LCD from Sure Electronics
working with Lcd4Linux.
The device works via LCDSmartie on Windows, so I recon the hardware is OK.

I've tried a lot of MatrixOrbital driver models, but none have worked.

Looking at the device manual
http://www.sure-electronics.net/download/DE-LD023_Ver1.0_EN.pdf

It show that to establish communications, the command
'\xfe\x53\x75\x72\x65' (Sure) must be sent.

Looking at the MatricOrbital driver code (the best that I can), it
does not send this sequence for the Sure model that it support.
http://ssl.bulix.org/projects/lcd4linux/browser/trunk/drv_MatrixOrbital.c

Just wondering how much effort would be required to support the newer
Sure model.

Regards

Matt

[lcd4linux] Visualizations

[Scott S. <sis...@gm...>]

I'm not sure if I ever showed these music visualizations for character
displays with 8 special characters. The 32x32 sized visualization is done by
LibVisual.

[lcd4linux] LCD4WoW

[Scott S. <sis...@gm...>]

It's kind of poor quality. LCD simulations in World of Warcraft.
http://www.youtube.com/user/sflynn2012#p/a/u/0/B5zQhRo7rN0

What I did here is I extended your layering scheme to character displays and
made the space character the alpha channel. You totally need to do that in
LCD4Linux. Hey, Linux is getting more popular among geeks. Maybe I'll spark
some interest for LCDs. I'm making large chunks of the game's information
available and visualized on some surface. I've done the tooltip driver and
the Text module for StarTiip, which is basically a driver. I'm working on a
graphical simulation of a character display at the moment. You don't want to
get too big with these though. I'll likely have to put in hard coded limits.

Also, I wanted to mention that your graphical display design, which is
updated in realtime, will be a whole lot lighter if done with a single
repeating timer, so widget:Draw() only updates the frame buffer. The entire
display is redrawn at every refresh interval. I'm about to do that to
character displays as well, and make it configurable. Either the player can
have it update in real time or they can have it update on a refresh timer.

I want to encourage you to work on LCD4Linux. If not but to write some
drivers for the latest hardware, find room to make a release. I'm going to
see if I can spark interest in LCDs and Linux. :) I can have this at least
mature-beta by the next expansion later this year. I want to see players
sharing displays over addon communcations. You just send a serialized
version of the display's configuration (including layouts and widgets) to
another player and they see your best presentation. Or you can receive a
upload request from another player and you choose to accept the display or
not.

Also, I'm going to bug you about the fact that LCD4Linux's character display
is so weighed down by the bars code. You can't add widgets without
containing the growing segments of a bar widget. Instead of allocating space
for all icons, allocate space for bars, and allocate space for each icon.  I
know that the character displays are a thing of the past, but I still used
it in LCD4WoW, since it's lighter to simulate a character display (with no
special characters) than it is a graphics display. A 256x64 cell graphic
display would cripple WoW. I'm getting by right now with a 1x20 sized
simulation of a 7x8 character display. Write a character display simulation
for LCD4Linux. :) You can have all the special characters you want.

[lcd4linux] Sure Electronics DE-LD011Problem

[Андрей <fro...@li...>]

Hello everybody!

I ordered display DE-LD011 from "Sure Electronics". I want to use this model with LCD4Linux. And there is problem here. This screen is in the
list of supported: http://ssl.bulix.org/projects/lcd4linux/wiki/MatrixOrbital. But when I set value 'DE-LD011' for parameter 'Model', I get an error: MatrixOrbital:
Display:DE-LD011.Model 'DE-LD011' is unknown. I
tried to set value 'LK162-12'(this screen is the same size, but other protocol) instead of 'DE-LD011'. In this case, the top line displays 'LCD4Linux 0.10.1' instead of 'LCDSmartie'. But widgets are not displayed. I can not understand what the problem. Text of my lcd4linux.conf file:

Display DE-LD011 {
    Driver 'MatrixOrbital'
    Model 'LK162-12'
    Port '/dev/usb/tts/0'
    Speed '9600'

Re: [lcd4linux] (no subject)

[Yago F. H. <st...@so...>]

Dear developers:

I've tried with picoLCD 2x20 with not very good results in the project I
am working in, so I have bought a new
LCD module picoLCD Graphic USB 256x64 with better results. This display
has 5 buttons that lcd4linux reads right.

The problem is that I need to give functionalities to these buttons and
have tried to read the whole wiki and using the 
help and the plugins. I have tried to give a button the function of
poweroff using the exec plugin, and to other the 
function to switch on and off the backlight with the command.

LCD::backlight(0)
LCD::backlight(1)

I have tried to use the command with evaluator as

expression
button_action=nkey==2?LCD::backlight(0):button_action;nkey==2?1:0

But after killing and restarting lcd4linux begins to run and to send
everything to the display until it comes to this line
and then exits.

My version is: Version 0.10.2-SVN-796 (the one that comes bundled with
picolcd)

Can you please help me to make it work!

Oh and I also used the layering idea on a single pixel -- the entire screen.
The addon's name is AuraAlarm. It alerts you to buffs and debuffs by
flashing the screen or whatever. You can prioritize an alarm by setting
opacity to 255. That part still needs work, but this tooltip addon got to
going. Pretty cool huh? Can't do the layering on the tooltips though. They
have to be character displays. I'm going the whole nine yards. Evaluator
wraps lua's loadstring. The configuration's almost exactly the same, except
it's done in lua tables. Properties too. Everything that went into
LCDControl. Plus the extras I added to LCDControl. These little tooltips are
going to be highly configurable just like LCD4LInux. You just tell it some
information like size and a few handlers, and viola an addon author can

I think the picoLCD is ok. unfortunately I don't have one ready to test. Maybe there's a problem with 
double-buffering... Does 'lcd4linux -Fvv' report any errors? (probably USB errors?)

> Another question. Can I change the widget every x seconds to another one?

No unfortunately you can't.

Dear support:

First I have to thank you for your good quality software and for your
efforts. I am deploying a new project using an alix3.d3 motherboard and
a picolcd display. It works with the widgets and I am happy enough. The
problem is that it does not refresh the screen well. Some characters are
not deleted after refresh and some are just not printed. Is there a
workaround that can help me to solve it? Maybe the LCD is not the best I

Another question. Can I change the widget every x seconds to another

How do you run lcd4linux?

Maybe you run the "installed" version (located in /usr/local/[s]bin) and not your compiled version?

Try "./lcd4linux -Fvvi"


Yust a quick guess.... Michael

[lcd4linux] adding a plugin - works only in GDB

[<Dav...@cs...>]

Hi,

I have put a quick plugin together for showing the battery state on my laptop, more than anything just to learn the format of plugins and how to add them.

I followed the Wiki instuctions to add all the extras in plugin.c, Makefile.am and plugins.m4.  The build appeared to work fine but when I tried to call the new function in interactive mode I got this...

eval> battinfo()
Evaluator: unknown function 'battinfo' in <battinfo()>
''
eval> 

After much hair-pulling and double checking, I tried running lcd4linux under GDB in interactive mode... it works

eval> battinfo()
Evaluator: wrong number of arguments in <battinfo()>
''
eval> battinfo('charging state')
'charged'
eval> 

>From a bit of googling, it seems that when things are working under GDB, but not normally, it is a threading problem. From what I have seen, in interactive mode there are no threads...  any ideas???

For the record, When running under GDB, the display will work with my plugin in non-interactive mode

Thanks in advance..

I have been playing with the picoLCDGraphic 256x64 for a couple of weeks now and can't seem to get an image working.

I have gone through the wiki and tried the examples, but nothing seems to work..

Is there a limit on colour depth of the image??

Any help appreciated...

Thanks

Re: [lcd4linux] Pertelian X2040 on tinycore linux

[Nathan B. <nat...@gm...>]

Hi there Rupert,

Thanks for your help! I will definately look into pertd. If you want some
advice on how to build lcd4linux on ubuntu: There are changes in the svn
repo that dont seem to have made it into RC2. This gives an "undefined
reference to `rdtscl'" error, but after some research I found that this
problem had already been addressed and patched. I just needed to checkout
the latest version from svn. Also, I can remember needing to install a
'libXXXXX' package with apt-get, but cant quite remember what it was..
'libtool', maybe? Also, if you wanted to compile it without any extraneous
dependencies, you can just use './configure --with-plugins=XXXXX', and
specify the 1 or 2 that you need.

I actually got it to work 2 minutes after pressing send on the last email I
wrote ... It turns out my thin client was still overloaded with perl, mysql
and sqlite, since it only has 128MB RAM, some of which is used as the file
system. But I rebooted it, and everything seems to be working smoothly :)

Now just to code a shell-fm plugin and design a layout ...

Cheers,
Nathan B


Well, you got further than me, I couldn't even get lcd4linux to build on my
Ubuntu Karmic box due to dependency issues and sadly no one on this list
replied to my queries.

I ended up using the pertd application developed by some dude over at
Pertelian:

http://www.pertelian.com/joomla/index.php?option=com_content&task=category&sectionid=7&id=23&Itemid=49

(check the community download link as well - though the above link lists all
the programs you'll need)

It actually works quite well, there are two versions, pertd and pertd2.
IIRC pertd takes input from simple takes files stored in /var (the readme is
very comrehensive) whilst pertd2 takes input from a fifo pipe. I could never
get the fifo pipe to work, so I stuck with pertd instead. It works really
well and has been running 24*7 on my Intel DM501 (the newer version of the
Intel Atom 330) for about a month non-stop. It seems to only use a small
amount of CPU and RAM so I am happy.

The quality isn't brilliant, the text flashes as it scrolls and it there are
some extraneous characters as new text enters the screen to scroll along,
but overall I find it ace. I use bash scripts to update the text files, the
scripts being run via a cron job.

Currently it displays:
Line1: sys load 1min 5 mins and 15 mins, memory usage
Line2: temp of CPU, Northbridge and HDD from lm-sensors
Line3: Currently Recording / Next Recording and Scheduled Recording from
mythtv (via mythstatus) since the box is primarily a mythtv box
Line4: Any WARNING error message from syslog and if that is empty, a check
that the internet is up and disk space usage info.

Overall, I would highly recommend it. You might get nice looking stuff out
of lcd4linux, but since I couldn't even build it, I gave up.

Hope this is usefull.
Rupert

[Nathan B. <nat...@gm...>]

Hi,

To follow on from my last email, I figured out how to compile lcd4linux with
the 2 plugins that I needed, and have got it running (somewhat) on tinycore
linux, on a compaq evo thin client. However, the buggy Pertelian driver
issue still remains. This time, its even worse ... It was quite bad on my
64bit ubuntu machine, but its absolutely unreadable and scrambled when
running on tinycore linux. Can someone advise if I could somehow fix this
with a tweaked parameter or something?

Cheers,
Nathan B

[lcd4linux] Pertelian X2040 on tinycore linux

[Nathan B. <nat...@gm...>]

Hello,

Today I received my Pertelian X2040 LCD display, and I am trying to get it
to work on linux. It works fine on my windows box with the Pertelian
software. But when I compile lcd4linux and run it with a simple test string,
the text gets all mixed up and letters appear in random positions. I dont
know if the reason is because I am running it on a 64bit processor which
hasnt been tested before, or if its because Pertelian have updated the
devices firmware in some way.

Also, I would love to ask if anyone could tell me how the 'mysql' and
'sqlite' dependencies can be turned off? I want to run lcd4linux on tinycore
linux, and I don't want to have to load mysql or sqlite.. I was looking at
"./configure --help" and saw that you can turn off plugins, but which plugin
do I need to disable to get rid of sqlite3? Or, a better question would be:
is there a way to disable ALL plugins, except for the 1 or 2 that I want?

I will download and install 32bit ubuntu on my laptop tonight and see if the
LCD works properly on lcd4linux.

Cheers for your help,
Nathan B

Re: [lcd4linux] Shell.fm on LCD4Linux

[Scott F. <sc...@st...>]

The Pertelian display's about the cheapest I've found. There's also
the PicoLCD graphic display
which is pretty cheap, but it is not an external.

[lcd4linux] Shell.fm on LCD4Linux

[Nathan B. <nat...@gm...>]

Dear mailing list,

I have a small project that I am developing. Its a Last.FM internet radio
player, that can be controlled over a network (wirelessly). I also would
like it to have a simple LCD interface that will display the artist and
track data, and allow the user to change stations/playlists via a mini usb
keyboard <http://www.cartft.com/catalog/il/478>. I am using the board from a
Compaq Evo T20 thin client, and have flashed the firmware with tinycore
linux to run shell.fm <http://nex.scrapping.cc/shell-fm/>. I am currently
coding some extra features into shell.fm, and would love to code an
LCD4Linux plugin.

I would just like to ask for some help with choosing an appropriate LCD
display. I found the Pertelian X2040 here: (
http://usb.brando.com/prod_detail.php?prod_id=00666), and it looks good and
reasonably cheap to me. I'm planning to scrap the plastic case and embed the
LCD itself in the box I'm making. Can anyone recommend a cheaper/better USB
LCD that I can buy online? (Ideally with 4 lines.)
I don't really want to get into making my own and programming
microcontrollers or anything, I'm just keen to find something that is proven
and easy to get working with LCD4Linux.

Finally, I would love to hear from anyone who has already done a similar
kind of project with LCD4Linux, whether its for shell.fm or MPD.

Thanks,
Nathan Broadbent

[lcd4linux] New firmware for LCD2USB with extended keypad support...

[Thorsten G. <dl...@gm...>]

Hi,

maybe also an interesting issue for the LCD4linux/LCD2USB-users:

i extended Till Harbaum's firmware x.08 for LCD2USB to support
a up to 12 pushbuttons keymatrix and did some further updates.
Here is the complete list of changes:

- Latest V-USB sourcecodes 20090822 used.
  Replaced "avrusb" by "vusb".
  Used latest "usbconfig.h" and modified it for LCD2USB.

- Latest USBTINY sourcecodes v1.4 used.
  Therefore replaced "main.hex/elf" by "firmware-usbtiny.hex/elf"
  in usbtiny/common.mk.
  Therefore added prototype of usb_setup() within the #ifdef-branch
  for USBTINY: 
  :
  #define usbInit()  usb_init()
  #define usbPoll()  usb_poll()
  
  // Prototype of usb_setup()
  byte_t    usb_setup ( byte_t data[8] );
  #endif  
  :
  
  Removed "extern" from usb_setup().

- Changed startup message from
  "LCD2USB V1.08 both!"
  "2nd ctrl both!"
  to
  "LCD2USB V1.09 1st OK"
  "LCD2USB V1.09 2nd OK"
  
  where "1st" is the first LCD-controller controlled by EN0 and
  "2nd" is the second LCD-controller controlled by EN1.
  "OK" is written to both at a time wirh EN0 and EN1 activated.

- Added extended keypad functionality (see Keypad.txt).
  A keypad with up to 12 keys can be connected to the existing
  hardware. The extension is backward compatible to the PCB version
  1.1 by Till Harbaum.
  
- Added a "LCD2USB SMD-Edition" (see LCD2USBsed_Front.jpg and
  LCD2USBsed_Back.jpg). The board has a cuttable 7-buttons keypad.
  The keypad can be used with LCDproc (Keymatrix_X_Y).

The complete package with the latest firmware can be found here: 
http://www.dl9sec.de/LCD2USB/LCD2USBsed_1V0.zip

It would be interesting for me, what happens with the additional
buttons in LCD4linux and how they are handled, because i usually
use LCDproc. Maybe someone can try it.
The matrix coordinates are mapped into the lower and higher nibble
of the scancode return value (see Keypad.txt).

Have fun...

Regards, Thorsten
