Hi New user here. I am having problems compiling the latest version from SVN. Here is the output of the ./configure command: http://pastebin.com/fXYfFPb7 And then, when I try to make (using sudo for both as I am in /usr/local/src) I get this: CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /usr/local/src/lcd4linux/missing --run aclocal-1.11 -I m4 aclocal-1.11: couldn't open directory `m4': No such file or directory make: *** [aclocal.m4] Error 1 After mkdir m4 I now get this error: rupert@noah:/usr/local/src/lcd4linux$ sudo make cd . && /bin/bash /usr/local/src/lcd4linux/missing --run automake-1.11 --gnu Makefile.am:16: required file `./ltmain.sh' not found make: *** [Makefile.in] Error 1 Something clearly not right here.... As I have already successfully built ffmpeg and x264 from source, I am pretty sure I have all the required build tools (automake is already up-to-date). A google search doesn't show anything. Any pointers what is wrong? Rupert |

Hi, I am running Debian Lenny and I had checked out the code yesterday for lcd4linux. picoLCDGraphic works fine but it does not add plugin_mpd. configure script is not able to find libmpdclient.h and shows this warning: checking for mpd_newConnection in -llibmpd... no configure: WARNING: libmpdclient.h header not found: mpd plugin disabled configure: WARNING: get libmpdclient.h from http://www.musicpd.org/libmpdclient.shtml configure: WARNING: and copy those 2 files in the lcd4linux directory. Going to the suggested URL takes me to the wiki main page for MPD and there are no such files for download. As a workaround I had copied libmpdclient.h from /usr/include/libmpd to the source directory of lcd4linux but it can't find it even. Then I tried with 0.10-rc2-2 and 0.11.0-SVN (pre-release) source code where it finds libmpdclient.h copied to local source directory but while running make, it errors out with following message: gcc -DHAVE_CONFIG_H -I. -D_GNU_SOURCE -Wall -W -fno-strict-aliasing -g -O2 -MT plugin_mpd.o -MD -MP -MF .deps/plugin_mpd.Tpo -c -o plugin_mpd.o plugin_mpd.c mv -f .deps/plugin_mpd.Tpo .deps/plugin_mpd.Po make[1]: *** No rule to make target `libmpdclient.o', needed by `lcd4linux'. Stop. make[1]: Leaving directory `/root/lcd4linux-0.11.0-SVN' make: *** [all] Error 2 Could someone please provide few pointers to resolve the issue.

I think this is a known issue, which should already be fixed in SVN. There was a bug in a delay loop, causing it to loop forever when time jumped backwards. Please test with the current version from SVN. If the issue still exists, I will investigate further. bye, Michael -- Michael Reinelt <mi...@re...> http://home.pages.at/reinelt GPG-Key 0xDF13BA50 ICQ #288386781 |

Greetings, I'm using lcd4linux from several months and I found it very usefull. Actually it is quite stable and reliable, but have some minor issue. Expecially when I hibernate the computer, after resuming, lcd4linux simply hang. Sometime restarting the process help, sometime I need to kill -9 lcd4linux/G15_Thread, some other there is no way to get it back to life. I simply need to reboot. It happens as well when I suspend or when I ntpdate over internet, but less than with hibernate. There is any way to fix this? Thank you, Lorenzo |

Hallo, maybe you can write to a RAMdisk? Or do you already? If you have another solution (f.e. FIFO) let us know.

Sorry for writing to the wrong address! ---------- Forwarded message ---------- From: Richard Müller <mue...@go...> Date: 2010/1/4 Subject: write to lcd4linux from an application? To: lcd...@li... Good evening, I successfully (thanks for helping) run a display at my parrallel port and I want to use for showing the output of a (pascal coded) application. (The application reads from two serial ports, and the results, computed by the program from the port's reading, should be displayed). I tried to write the output to a file and display the text by using the readfile plugin. But that means to open and close the files over and over and that doesn't lead to nice result. Can I treat the lcd as a file and write to that file, as I would do with serial displays? The background is, I am constructing a portable measuring unit with no monitor, it has only that lcd for output. Richard -- Richard Müller . Am Spring 9 .

your config lacks at least a line reading
Display 'HD44780-16x4'
Background: You can define more than one 'Display' Sections, and with a single 'Display' Setting you select one of them
But your config seems very incomplete to me: there are no widgets, no layouts, ....
bye, Michael

Hi again,
> I've fixed it. Sorry
No problem.
Ok, so you can try try following conf:
Display DT164A {
Driver 'HD44780'
Model 'generic'
Bus 'parport'
Port '/dev/parport0'
Controllers 1
Bits 8
UseBusy 1
GPOs 0
Backlight 0
Size '16x4'
asc255bug 0
Icons 8
Wire {
RW 'AUTOFD'
RS 'INIT'
ENABLE 'STROBE'
BACKLIGHT 'GND'
GPO 'GND'
POWER 'GND'
}
}
Widget Heartbeat {
class 'Icon'
speed 800
Bitmap {
Row1 '.....|.....'
Row2 '.*.*.|.*.*.'
Row3 '*****|*.*.*'
Row4 '*****|*...*'
Row5 '.***.|.*.*.'
Row6 '.***.|.*.*.'
Row7 '..*..|..*..'
Row8 '.....|.....'
}
}
Widget Test {
class 'Text'
expression '1234567890123456789012345678901234567890'
width 40
foreground 'ff0000ff'
}
Layout Default {
Row1.Col1 'Test'
Row4.Col16 'Heartbeat'
}
Display 'DT164A'
Layout 'Default'
If it is running you should have a Marquee-style 1234... in the first
line and a pumping heart in the lower right corner of your display.
Maybe you can try some things before:
Power your LCD with the 5V (no further connections) and tune the contrast
pot so that you can see a black bar in the first and third line. So you
can be sure to see something if the display is fed with data.
The "R/W" isn't really nescessary. To exclude some errors, you can
pull pin 5 (R/W) of the LCD to GND and set the wiring definition
in the conf to "RW 'GND'" and disable use of the busy flag by setting
"UseBusy 0". So the display is "write only" but depends on a good
timing (it should!). If the busy flag is enabled, the timing is done
a bit more efficient, but that's not really important yet.
Another thing:
Be aware not to burn your backlight pot! The datasheet says 280mA@4,2V
for the gn/ye backlight. So Rv=(5V-4,2V)/280mA=2,9R. That means about
224mW of power dissipation...
Good luck!
Regards, Thorsten

Hi Richard, > http://www.phytoplankton.info/download/anschluss.gif Sorry, but this link doesn't work for me. Can you write a little table with the connections? E.g.: Parport - LCD D0 (2) - DB0 (7) : > Port '/dev/parports/0' Does this device exist? In my Debian it is named '/dev/parport0' Maybe the problem could be an incomplete 'Display' definition. When you omit to declare a parameter it uses the default value, which may causes a malfunction of the display. Try to use a complete definition (apart from the timing stuff) with the wiring infos. But first of all we need the connection info... Regards, Thorsten |

Hello, I have a 4x16 LCD Display "Displaytech 164A" for the parallel port. I am not sure, whether its controller is compatible with the HW44780. The datasheet shows a KS0070B controller. I tried to use it as HW44780, but with no success. Perhaps it's the wrong controller or perhaps my lcd4linux.conf is faulty... Unfortunately I could not find any information regarding the compatibility of my display. But maybe one of you knows it and can help me farther. (Attaching a config-file (for version 0.10) is not forbidden...) Thanks in advance Richard -- Richard Müller . Am Spring 9 . D-58802 Balve www.oeko-sorpe.de |

Hi,
i have a question about lcd4linux and its keypad support.
Originally i use a LCD2USB (no pushbuttons connected) and a keypad
matrix connected to parport0 together with LCDproc/LCDd.
The keypad is connected as following:
+5V ----------+--------+--------+--------+
| | | |
22k 22k 22k 22k
| | | |
/STRB (1) -|<---+--------+--------+--------+ |
| | | | | | | |
o | o | o | o |
S1 \ | S2 \ | S3 \ | S4 \ |
o | o | o | o |
| | | | | | | |
+---+ +---+ +---+ +---+
| | | |
/LF (14) -|<---+-----------------+--------+ |
| | | | | | |
o | | o | o |
S5 \ | | S6 \ | S7 \ |
o | | o | o |
| | | | | | |
+---+ | +---+ +---+
| | | |
/ACK (10) ----------+ | | |
BUSY (11) -------------------+ | |
PE (12) ----------------------------+ |
SELIN (13) -------------------------------------+
Is it possible to use the LCD2USB together with the keypad with
lcd4linux? If there is no direct keypad support, can i use the
GPIO support of lcd4linux to make the keypad usable?
Thanks in advance.
Regards, Thorsten

Hello, I'd like to purchase a lcd display from sure electronic : http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250501014655&ssPageName=ADME:X:RTQ:US:1123 but i'm not sure of it's compatibility with lcd4linux. The lcd module seems to be HD44780 with a Silicon Labs CP210x USB to UART Bridge. I want to put it on my old iBook converted in a file server / media center so i'm stuck to usb. These LCD displays are very cheap it would be great if they were compatible. Best regards, Cyrille2 |

I'm using Devil Linux, and trying to get the IP address to show up on
the LCD, but it seems that the version of lcd4linux is only at 0.10.0
for this distribution (it's a pain to upgrade, because we are booting
from flash).
One way I'm trying to do it, is to use a file that contains multiple
lines. It will read 2 lines to display on the LCD, and then read the
next 2, and so on. But, either the Timer is not working (I have a
widget, and it is in the layout), or the assignment ("=") is not
working, but it's not really giving me an error. Is the timer widget
new to like 0.10.2 or something? (It would be a good idea to put
version numbers in the plugin doc pages). I'll would just update the
file on occasion with the info I need using a different program, but I
can't seem to get it to read any more than one screen of lines because
timer isn't working.
Alternatively, if the netstat plugin was available, I would use it,
but I think my version is too old for that one as well (again, not
specified in the docs, but it should be).
If I could write a plugin, I would, but it's hard for me to change any
directory except for /etc and /root, and I don't know where plugins
are kept (if they are even separate from the lcd4linux binary).
Thanks for the help,
Brad Landis
