Look at the web page (http://lcd4linux.sourceforge.net). The pixmap 
device is a Meta-Driver, The Output is the same as e.g. the X11-Driver 
(both are pixmap-devices)

again: non-existant :-)

Well, not really. The only widget which uses the graphic capabilities is 
the bar.

I had some thoughts in mind about "plots" ore something, but never 
implemented them.

No, not at the moment. l4l does not support this, but the T6963-driver 
would. T6963.c uses pixmap.c, which provides sort of a "graphic 
framebuffer", where Textx and bars are rendered into. The flush() 
function within T6963.c sends this framebuffer to the display (using 
double-buffering to save bandwith).

You are very welcome to do so! BUT! Do it within the pixmap device, so 
every other graphic display would have these features, too (without any 
changes to the driver!). At the moment, all the pixmap-drivers (X11, 
PNM, PNG) would have icons!

If you plan to change something, _PLEASE_ use the CVS code! (I recently 
implemented a new "parallel port abstraction layer", so the parport 
stuff looks even cleaner now.

Another thing: You don't have to wait for your display, use the X11 
driver for development and testing. Believe me, as soon as you get your 
display, it will work. (And I sooner get your code :-)

If you have any questions about the internal structure, feel free to ask me!

I think you'd best start with pixmap.c, implementing some new functions 
which draw things into the framebuffer.

Have fun!

Okay, I'll rephrase my question:
How good is the graphics-mode support in l4l? ;)

I mean; will I be limited to the chars and symbols offered by l4l, or can I
actually dump small bitmaps to the display and/or control it pixelwise?

If that's not possible yet, it will definately be
the first thing I'll try to hack up once I got my display.

I took a quick glance at the code and all the scary parallel-port stuff seems
to be nicely wrapped, so I might actually be able to do it even tho my C is,

Well, the T6963-driver supports graphic mode _only_ :-)

The display is used as a raster device, all the font rendering, bar 
rendering and so on is done in lcd4linux. This way, you get "perfect" 
bars, because there's no limitation of user-defined characters as in 
other displays.

[lcd4linux] T6963c support?

[Moe W. <es...@an...>]

Hello,

does anyone know whether there are any plans to support the graphic mode of
T6963c driven displays in lcd4linux?  After some intensive googling it seems
to me like there's no software/driver available to make use of the graphics
mode with linux, yet.

how good is the text-mode support in l4l anyways?


thanks for any info!

[lcd4linux] Repost: new "parallel port abstracion" in CVS

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

Hi there,

sorry if you get this message twice. I'm reposting it because I did not 
receive a copy myself, and I posted to the wrong email-adress...

So here it goes:

I implemented a new "parallel port abstraction scheme" into lcd4linux.
This new feature is only available in CVS at the moment, as I'm looking
for some testers.

First I want to thank Thomas 'Silvo' Volkert for having this idea.

What's this abstraction layer:

- for the user: you can specify the wiring in the config file. This way
it's possible to run lcd4linux with almost all wirings out there
(WinAmp, lcdproc, ...)

For HD44780, just specify the following lines in lcd4linux.conf:

Wire.RW          "GND"
Wire.RS          "AUTOFD"
Wire.ENABLE      "STROBE"
Wire.GPO         "INIT"

This would be the traditional lcd4linux wiring scheme (which will be
used as a default if you don't specify any wiring in the config file).

Another example would be the WinAmp style:

Wire.RW          "AUTOFD"
Wire.RS          "INIT"
Wire.ENABLE      "STROBE"
Wire.GPO         "GND"


- for the developer: it hides all the inb()/outb()/ppdev() stuff from
the driver itself, lets you specify your own names for the control
signals, and takes care of the inverting of several signals (so you dont
have to invert-invert-invert your thoughts :-)

as an example, the HD44780 "send command" function looks that easy:

static void HD_command (unsigned char cmd, int delay)
{

   // put data on DB1..DB8
   parport_data (cmd);

   // clear RW and RS
   parport_control (SIGNAL_RW | SIGNAL_RS, 0);

   // Address set-up time
   ndelay(40);

   // send command
   // Enable cycle time = 230ns
   parport_toggle (SIGNAL_ENABLE, 1, 230);

   // wait for command completion
   udelay(delay);
}


this new scheme is implemented for the following drivers: HD44780,
M50530 and T6963

Please test and report!


TIA, Michael

Re: [lcd4linux] Monitor Eth0 on T1?

I'm afraid this does not work at the moment, but it's on my Todo-List 
for a while now.

The problem is that this would need a bit redesign in the token 
structure. There is a _big_ redesign ongoing, but at the moment only in 
my mind.

YOu could patch lcd4linux so it does not sum up all the eth* devices, 
but use only eth0:

system.c function Net()


while ((s=strsep(&p, "\n"))) {
     int n, u;
     unsigned long v[16];
     n=sscanf (s, " eth%d: %ld %ld %ld %ld %ld %ld %ld %ld %ld %ld %ld 
%ld %ld %ld %ld %ld",
	      &u, &v[0], &v[1], &v[2], &v[3], &v[4], &v[5], &v[6], &v[7],
	      &v[8], &v[9], &v[10], &v[11], &v[12], &v[13], &v[14], &v[15]);


==> add the following line here:
if (u != 0) continue;
==> done!

     if (n==17) {
       pkg_rx+=v[0];
       pkg_tx+=v[8];
       *bytes=1;
     } else if (n==12) {
       pkg_rx+=v[0];
       pkg_tx+=v[5];
       *bytes=0;
     } else if (n>0) {
       error ("parse(/proc/net/dev) failed: unknown format");
       fd=-1;
       return -1;
     }
   }


warning! This is untested!

This would skip every line except eth0


HTH, Michael

[lcd4linux] Monitor Eth0 on T1?

[Eric N. <eri...@di...>]

I have a firewall with 4 eth* ports on it.  My eth0 is connected to a T1 
which is rated at about 1.5mbit/s.  How do I configure lcd4linux to 
monitor only that eth0 port and show's the usage in kbps/s and as a graph?

If I can get this to work, I'll be able to see my T1's utilization at a

[Max W. <max...@pa...>]

Hi
I have never posted in a mailing list before so please forgive me if I =
get it wrong or something :-)

I want to install and use LCD4Linux on redhat 7.3
Heres is what i have done:

-extracted and untared the tarball.
typed this:[root@redhat lcd4linux-0.98]# ./configure --prefix=3D/usr =
--enable-drivers=3Dhd44780
then typed this:[root@redhat lcd4linux-0.98]# make (i assumed this part =
from LCDproc)

I have read the README file but thats for when its been installed right?

If i run INSTALL I get this:

[root@redhat lcd4linux-0.98]# ./INSTALL

Well, this has been fixed some time ago, but only in the CVS version. At 
the moment lcd4linux gehaves that way, if msr.h cannot be found, only 
the gettimeofday() delay loop will be used. But I will change this 
again, hard-coding the only small definition needed from msr.h into 
udelay.c:

#define rdtscl(low) \
      __asm__ __volatile__("rdtsc" : "=a" (low) : : "edx")

This may break architectures which doe not have an rdtsc command, but 
this should be checked during the parse of /proc/cpuinfo.

You're right, scrolling or havind multiple screens is not supported at 
the moment.

There's one workaround: you can provide several config files, and have a 
shellscript which periodically rotates a symlink over your 
configurations, and sends a SIGHUP to the lcd4linux process (which 
forces kind of a "restart", including re-read of the config file.)

At the moment I'm waiting for some test results of the Cwlinux driver, 
and will release 0.99 (or 0.9.9, I'm changing the numbering scheme) 
hopefully shortly. After that I'm thinking about a redesign, 
implementing a client-server modell (similar to lcdproc), but not on a 
"screen" basis, but based on windows and widgets (so one screen can 
display information from different clients).


bye, Michael

[lcd4linux] add to Compiling on 2.4 kernels and a question =D

[Ralph J. <pen...@ca...>]

hi just read all the posts i got one thing to add for anyone that might
possibly be trying to compile for 2.4 kernels, especially on RedHat
distribution.
 
    the install of the kernel-sources rpm is somwhat broken. there is a
directory in /usr/include named asm. libraries for assembly if i am not
mistaken. however the directory is missing some header files. the best
way to resolve this and not recieve errors due to a "missing msr.h file"
is by creating a symlink to the correct directory which is found in
/usr/src this helped me:
 
        mv /usr/include/asm /usr/include/asm.old
        ln -s /usr/src/linux-2.4.18-14/include/asm-i386 /usr/include/asm
 
I actually came across the resolution on a RedHat bulletin board. it
seems that for some reason they didnt add all the correct files into
/usr/include
 
Then proceed with make. be advised: in my case the directory was name
asm-i386 because that is my architecture. depending on what you are
running that directory may be different. just check out your own sources
directory. i'm telling you once i did that, boom boom, it compiled
beautifully and i had the thing up and running in less than 5 minutes.
 
I have a quick question, i did see in one post that scrolling is not yet
supported, i believe thats what i understood. However, is it possible to
create multiple screens, that are displayed at given intervals? I did
see a post about this but it was never answered. Also I did notice that
some of the new CrystalFontz LCDs do have inherent scrolling
capabilities, does this mean that if i send to it multiple lines it will
scroll on its own? I just havent tested it out for myself because i
havent yet bought an LCD, i've just been messing around with the X11
driver, which i think is excellent. Any help with this would be greatly
appreciated. thanks!

They look cool!

Hmm. Normally these USB displays just consist of a USB-Serial or 
USB-Parallel converter and a "standard" LCD driver chip. In every case 
you'd need a kernel driver.

I got an "USBLCD" from a guy from germany, but this is just an interface 
  to any HD44780-Display.

And I'm going to order an USB display from CwLinux.

But none of these will help you.

Maybe the guys from lcdproc already have a driver?

If you find anything out let me know!


bye, Michael

[lcd4linux] USB Matrix Orbital?

[Peter D. \(Volt\) <a-p...@mi...>]

Hello,

I just received a new LCD from Matrix Orbital that uses the USB port.

I fear that this is going to be a dead end...  The kernel sees it, but
doesn't recognize it as anything.  I cant seem to find anything in /dev
that would be it, so don't know where to go from there.  Is there
something in the kernel I should include?

Running Gentoo 1.4_rc2.

Thanks!

Re: [lcd4linux] Display works! :-) Thanks

You are using the latest .tar.gz-Release, right? It's more than a year 
old, and if I remember correctly, there's been a bug with plugins 
(something with CR/LF).

You could try the most recent version from CVS, I tested your plugin 
with this, it works fine.

If you need assistance with CVS, let me know, I'll help you.

The list is english, but you can contact me personally and in german :-)

[lcd4linux] Display works! :-) Thanks

[Matrix1000 <Mat...@gm...>]

Hi,

I've chanced some pins and now it works.

Now I have only a small question.
I insert an command:
date |cut -d ' ' -f 5
for %x1
So the entry is:
Row1: "%x1Time"
But between the timeoutput und the word time is
one field with trush. What is it? It looks like an bar?!

Thanks!
P.S. Is this mailinglist an englishspeaking list or is it ok
if I write in german?

Re: [lcd4linux] Hi. I've got a Question.

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

Hi Matrix,

Which "windows versioN" do you compare? There is no windows version of 
lcd4linux. Maybe you're talking about any other windows software.

I'm quite shure that you're using a wrong wiring. Take a look at 
"README.HD44780" and compare your pin wiring.

looks fine. If you get it to work, you should change the "Port" entry in 
lcd4linux.conf back to "/dev/parport0", the ppdev() driver is the 
cleaner solution.

Could it be possible that I have to chance some Pins on
the lpt-stick? Mayby it must be different to the windows version??
I'm absolute not sure.
