please help me

excuse for my english

unsigned char buffer[22] needs to be at least 24

hi,

i need just a small hint i cant find around in the wiki documentation and in forums: how are the virtual rows working? i mean in wich position of the config file should i put rows, scroll and turn options?? i dont get also this little mess about sections.. the format changed i know.. for instance this is the old 9 format here? :

https://ssl.bulix.org/projects/lcd4linux/wiki/Sample_09 while this is the new? https://ssl.bulix.org/projects/lcd4linux/wiki/lcd4linux_conf right? they are not compatible i immagine..

so.. and..in reality there are also a couple more thinks.. if you have time to go trough them: i get also some errors about sensors at startup: Feb 17 13:03:56 scarpiera LCD4Linux[32205]: i2c_sensors: unable to autodetect i2c sensors! infacti i didnt get them to work (anyway i didnt get how would i set the sensors device in shfs.. here there is no clue: https://ssl.bulix.org/projects/lcd4linux/wiki/plugin_i2c_sensors an then other errors about compile time missing include..: Feb 17 13:03:56 scarpiera LCD4Linux[32206]: udelay: The file 'include/asm/msr.h' was missing at compile time. Feb 17 13:03:56 scarpiera LCD4Linux[32206]: udelay: Even if your CPU supports TSC, it will not be used! Feb 17 13:03:56 scarpiera LCD4Linux[32206]: udelay: You *really* should install msr.h and recompile LCD4linux! wht is this msr used for? advantages? i have such a file in my 2.6 kernel source tree but i didnt get ./configure to get it to see.. uhm..

ok, thanks a lot if U have time to go trough this, tent:wq

Hello

i problem for SC2002A because i don't know driver for lcd4linux. u can config simple for LCM Model SC2002A

Thank you very much

*i speak little english :(

I've been Suse 8.2 and a CFA632-NFA-KU Display by Crystalfontz. My problem is that the LCD4Linux didnt connect to the Display. I think the problem is in the Config file of LCD4Linux, there who the port for the display is the port for the FTDI_SIO, if I mount that to a folder and set it in the configfile --> it doesnt work! Plz help me

My gosh.

-Hardware ok. -Firmware upgraded! -Debugs looks perfect. -Conf REALLY OK. (minimal conf) -strace looks good! what else?

DOESNT DISPLAY ANY F*K DATA !! going crazy. somebody help.

i attach strace and little debug.

Hi there, I'm a bit stumped. I own a CFA2004A-TMI-JP LCD from CrystalFontz? that I was trying to get going with lcd4linux.

When running the program with any "}" characters it throws up an error "' is invalidfig file '/etc/lcd4linux.conf' line 4: key '}"

If I remove the offending '{'s and run lcd4linux, I receive the following error "Jade:/home/whale# lcd4linux

: garbage <arse error in <'HD44780-winamp'

missing 'Display:HD44780-winamp.Driver' entry in /etc/lcd4linux.conf!"

My lcd4linux file is attached, perhaps someone can tell me what I have messed up :)

Thanks for your help,

Hallo NG

kann jemand mit dieser Fehlermeldung was anfangen? Wollte lcd4linux installieren gcc -DHAVE_CONFIG_H -I. -I. -I. -D_GNU_SOURCE -Wall -W -g -O2 -c drv_BWCT.c drv_BWCT.c: In function `drv_BW_open': drv_BWCT.c:114: parse error before `int' drv_BWCT.c:115: `c' undeclared (first use in this function) drv_BWCT.c:115: (Each undeclared identifier is reported only once drv_BWCT.c:115: for each function it appears in.) make: * [drv_BWCT.o] Error 1

My LCD model is Cwlinux Model: Cw16x2 I want to show my host IP address in the LCD, how to write the Widgets. or maybe how to capture the ip address as command ifconfig.

Thanks

After a couple of hours of running, my screen shows corrupted characters. I have set the timings to give more time to the LCD but it has no effect.

after successfull ./configure I get following error after a few lines of make:

"drv_SimpleLCD.c:212: warning: pointer targets in passing argument 6 of 'cfg_number' differ in signedness"

I have a crytstal fontz cfa-631. It displays fine for a time but after 5 minutes to 1 hour the display stops updating and I get these messages in my logs. Feb 18 03:03:00 [LCD4Linux] Crystalfontz: write(/dev/usb/tts/0) failed: Resource temporarily unavailable Feb 18 03:03:23 [LCD4Linux] Crystalfontz: write(/dev/usb/tts/0) failed: Resource temporarily unavailable

I have to kill the lcd4linux program and restart it. It then will work for a while longer. If i run with the -Fvv option I get the following messages after the display stops.

Is this possibly a ftdi_sio driver issue? I am using a 2.4.28 kernel at present.

I recently tried to get lcd4linux to work with mpd. Installing lcd4linux worked like a charm, but I'm unable to get plugin_mpd to work. I tried severel linux distributions and several versions of lcd4linux:

Debian Etch Debian Lenny Slackware 12.0

lcd4linux 0.10.0 lcd4linux 0.10.1-RC1 lcd4linux 0.10.1-RC2

I tried the distribution specific packages as well as building lcd4linux from source (with the --with-plugins=mpd option), but still no success. Lcd4linux runs fine, but plugin_mpd is not loaded (even if executed with -Fvv) and the mpd widgets are not recognized.

The plugin is loaded via lcd4linux.conf:

Plugin MPD { enabled 1 server 'localhost' port 6600 }

When starting the lcd4linux daemon it connects to mpd, but the plugin still doesn't work.

Any help would be appreciated.

Hi Guys

I have an ST2205 display, it is on SDD, I can get it to display a pic with a tool called setpic. but I cannot get lcd4linux to do anything at all, it just runs and goes to the command prompt, the .conf file is setup for the driver, if I run it with -Fvv I get the below

Version 0.10.2-SVN-796 starting plugin_cfg.c: Variable tick = '500' (500) [FIFO] read 'Plugin:FIFO.fifopath', value is '/tmp/lcd4linux.fifo' [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 st2205

Can anyone help, it goes back to the command prompt straight after that

Hello,
I configured lcd4linux on a testing machine and copied everything onto my machine on which I want to use lcd4linux (it is the same hardware excepting hdd and ram). But somehow it does not work. This is the message lcd4linux delivers:
initializing layout 'info'
widget 'confirm_info': class 'Keypad' not supported
widget 'leave_menu': class 'Keypad' not supported

I would be glad, if someone is able to help me.
Thanks

Hello,

when I use string concatenation (using the "." operator) together with the precision attribute in the configuration file, the expression always evaluates to zero. The following code will produce the error:

Widget ppp0 {
    class 'Text'
    expression (netdev('ppp0', 'Rx_bytes', 1000) / 1024) . 'k/' . (netdev('ppp0', 'Tx_bytes', 1000) / 1024) . 'k'
    prefix 'Down/Up: '
    width 40
    precision 1
    align 'L'
    update 1000
}

In a working scenario, the output should be something like "Down/Up: 125k/14k".

Leaving out the precision attribute works, however it will result in very large floating-point numbers, which will unfortunately consume most of your LCD space.

Any workarounds, I have discovered have drawbacks considering positioning of the string on the LCD or are just too complex for this a simple task.

Otherwise, lcd4linux is a great project.

Everything is ok. But nothig display on.

why?

I don't think this is a LCD4Linux issue, but I am writing it up just in case...

Compiled for Linux 2.6.12 under CRIS for an Etrax LX. No problems there. Set configuration for a Crystalfontz 634:

Display CF634 {

Icons 0 Driver 'Crystalfontz' Model '634' Port '/dev/ttyUSB0' Speed 19200 Contrast 16 Backlight 50

}

// for the layout supplied I removed the last two rows (as my display is 4 rows, // although I suppose these just scroll via the driver).

Layout Default {

Row1 {

Col1 'OS'

} Row2 {

Col1 'CPU' Col10 'RAM'

} Row3 {

Col1 'Busy' Col10 'Rain' Col11 'BusyBar?'

} Row4 {

Col1 'Load' Col11 'LoadBar?'

}

}

Display 'CF634' Layout 'Default'

The display clears (I have another piece of code that writes something to it first) and then the kernel locks. All services die. The console (/dev/ttyS0) locks up. Nada.

I was having this same issue when sending control sequences to the display with my test program (written in C). I found it necessary to pause 100 microseconds or so between commands (not displayable ascii). I also found that many commands are ignored. I have a CD632 which has the same issue.

Now the Axis has a USB-based eth1 port (eth0 is a dedicated controller) and under kernel 2.6.x this has been known in the past to be problematic. I suspect this is a factor, but would welcome any suggestions from the experts before I revert to a 2.4 kernel and try again.

plugin_file.c: my_readline uses fgets which expects a newline character in order that data is returned for a line.

In my testing if I specify a widget:

Widget OperationStatusLine?2 {

class 'Text'

expression file::readline('/var/tmp/solarwave/statmsg',3)

align 'L'

width 20

update 1000

}

Then put it on the 4th line of my LCD:

Layout Default {

Row1 {

Col1 'Time'

} Row2 {

Col1 'Operation'

} Row3 {

Col1 'OperationStatusLine?1'

} Row4 {

Col1 'OperationStatusLine?2'

}

}

and if my text file has 5 lines (each has a newline character at the end) the process runs fine and I see from ps:

569 root 768 S ./lcd or 569 root 768 R ./lcd

S or R depending on its state ("lcd" being my name for the lcd4linux binary)

However if I remove the last newline, the process displays all but the last line, and then dies. As I expect, ps however shows that the application

569 root 776 R ./lcd

is always in the RUN state. It never seems to sleep and is only recoverable with killall -9 lcd

The console does not issue the message "readline requested line %d but file only had %d lines" which is also strange.

It appears that lcd4linux enters a race condition. Top is indicating almost 100% utilization.

What I'm attempting to do here is set up a channel whereby other applications can write to a certain file and have the contents displayed with a 1-second update. I'd rather the file operations be a little more forgiving.

Apart from this issue, one question: what happens when SetResult?() returns a null? It would be great if, back in the widget setup, one could say:

if (result==null)

don't erase the current data on the display

I don't see any way to do this, even if I were to re-write readline because it appears that once the function is called from the timer, you're committed to writing to the display.

I've created a patch for plugin_mpd.c, alot of new functions are implemented...

I have a Noritake 20x4 VFD which is based on the HD44780 chipset.

lcd4linux'es driver works perfectly, but there are some extensions to the chipset which would be nice to integrate.

One of these is the ability to set the brightness level of the VFD from 25% to 100%, (in jumps of 25%).

Anyone willing to do it? I'm willing to test it out.

I have two datasheets for the VFD. one of these includes information on setting the brightness (page 8 on my pdf viewer).

If you need any more information let me know.

Thanks.

EDIT:

Sorry but I can't upload any files, TRAC keeps giving me "Internal Error" when I try. so here are the datasheets:

I use openwrt and would like to build a (car) mp3 player. I want to use lcd4linux as my input/output handler... so far so good, but would lcd4linux be able to handle usb-keyboad input (via hid device)? Or is this a completely wrong approach?

Currently I'm using cmdpad for input handling (http://cmdpad.sourceforge.net/) but it would be nice if I could merge this action...
