I'm afraid this does not work at the moment.

Where does the long text come from? From a plugin? Then you could try to 
  change the plugin so that it splits the text into multiple lines.

[lcd4linux] version .98, CrystalFontz, and RedHat 7.3

[Junk C. <ju...@di...>]

Thanks to Michael for the wonderful program. For those of you looking to get 
this working on RedHat 7.3, perhaps with a CrystalFontz 632 display, I had to 
make a couple of adjustments.

First, the configure process doesn't find the msr.h file, even if I specify a 
path to look in so:

cp /usr/i386-glibc21-linux/include/asm/msr.h /usr/include/asm/

then

sed 's/usleep(350000)/sleep(5)/g' Crystalfontz.c >> Crystalfontz.d
rm -f Crystalfontz.c
mv Crystalfontz.d Crystalfontz.c

#Thanks to Herbert Rosmanith for the above fix

./configure
make
make install

cp lcd4linux.conf.sample /etc/lcd4linux.conf
chmod 600 /etc/lcd4linux.conf
chown root:root /etc/lcd4linux.conf

vi /etc/lcd4linux.conf

Add the appropriate lines to the file for you config, per the instructions in 
the README.Crystalfontz file

To run the program so that any messages are sent to the screen:

/usr/local/bin/lcd4linux -f /etc/lcd4linux.conf -F -vv

Hope this helps someone. Any questions, feel free to e-mail me at 
ju...@di....

[lcd4linux] HD44780 driver questions

[Carlos L. <car...@st...>]

In regards to the functions controlling communication, there was this
function:
void HD_write(char *string,int len,int delay)

But, there were also this one, which were further down the source file:
void HD_put(int row,int col,char *text)

The confusing thing is that there seems to be 2 ways to write to the LCD
through this code.
Neither calls the other, so there's no dependency there.

Question:  What does one function do that the other doesn't?

Thanks for your time.

Carlos

What do you mean with "-options"? I don't remember that there's such a 
option.

You could try to start it wit "-F -vv", which means "don't daemonize, 
and be very verbose", and have a look at the debug messages.

I'm pretty shure that there's something wrong with the wiring.

I'm building (trying to) a firewall/proxy/gateway based on a 486 DX4-100 with 16Mb Ram, 2 NIC's using ADSL (pppoe) for this i'm using coyote linux with 2.2.19 kernel, my idea is to use an embedded distro on a 2M Eprom, as the kernel will be 2.2.X I want to see how to compile on this kernel, which libraries I would need, (for delay.h or udelay as example) etc. As you can see is pretty much info for being asking over the list, so I think that perhaps the project is well documented and reading docs could find this items.

[lcd4linux] Problems with gd.h

[Jorge B. <int...@fi...>]

Hi, sorry if this is a FAQ but I can't find any documentation on what dependencies I need in order to compile lcd4linux. When I compile, after ./configure I receive :

gcc -DHAVE_CONFIG_H -I. -I. -I.    -I/usr/X11R6/include -D_GNU_SOURCE -Wall -g -O2 -c Raster.c
Raster.c:127: #error "gd.h not found!"
make: *** [Raster.o] Error 1

Any clue on what I need ?

Also I would appreciate any documentation on the project, or if PC2002A (20x2) is supported by the project.

Thanks in advance

Re: Re: [lcd4linux] isdn support

[Alexander P. <Ale...@de...>]

Hi Michael,
thanks for your response.
Actually, it did not compile  ... even after disabling isdn support. It
then complained about 'isblank()' and 'rdtscl()' not being there and a
reference to 'Isdn' in processor.c . :-(

So, I included a isblank() into cfg.c and commented out the Isdn code in
processor.c. Then I disable the rdtscl code in cfg.c and finally commented
out the group config check, as cygwin does not support rights...

That was all ;-)

>Why do you want to remove it? Are there any includes you don't have with
>cygwin?

Yes, make complains about <linux/isdn.h> not being there.

Well, this would help ... :-)

>Maybe the simplest solution would be a special preprocessor symbol...

Or to use a real Linux system, as cygwin does not have the complete
/proc filesystem ... :-( So, lcd4win is somehow useless here...
I only did this for testing purposes.

Why do you want to remove it? Are there any includes you don't have with 
cygwin?

Shure it's possible to make it optional. There could be an option to 
'configure' similar to '--with-drivers', I'd call it '--with-clients'.

But these options are quite complicated to write and to maintain, and 
they lead to a lot of #ifdef's, which doesnt't make the code easier to 
read (and to maintain).

How did you deactivate the ISDN stuff in the Makefile? I can't imagine 
that modifications to the makefile only would cleanly deactivate it 
(because other code refers to the ISDN stuff).

Maybe the simplest solution would be a special preprocessor symbol...

greets,

find the place in the CrystalFontz-driver which reads "usleep(..somevalue..)"
exchange that with "sleep(5)" and try again. you are probably using a new
display.

634 v2.0 needs a delay of approx. 5 seconds after opening in order to
work properly. can you find the position where to insert the delay?

maybe a "Delay" parameter should be a config-option then ...

no idea ... it gets overcrowded?

the crystalfontz has a total of (if I remember correctly) 8 characters which
can be defined freely. if the graphic you are trying to display is so
"complicated", that it cannot be built with this limited amount of configure-
able characters, you get the error-message "failed to allocate a custom
character".

[lcd4linux] trouble with CrystalFontz 634 2.0

[Barry G. <mai...@pe...>]

Hi, I'm trying to use LCD4Linux with a Crystal Fontz 634 v2.0 and am having 
some troubles...

1. Often, when running lcd4linux, the display lights up, but doesn't 
display any characters. Restarting lcd4linux 1 or more times fixes this.
I've got lcd4linux set to 19200, but 9600 seems to have the same problem.

2. The displays are fine with the default config file, but if I try to use 
the network graphs, the lcd eventually starts scrolling and gets unreadable 
quickly.

3. Sometimes I see
failed to alloc a custom char
if I run lcd4linux with -F

4. I have 3 nics; are the network graphs showing eth0 or are they showing 
the total?
Can I have one graph for each nic? I didn't see this in the docs.

Thanks,
Barry

Hello Michael,
Hello alltogether,

some comments to Michael`s mail will follow ..
> The M50530 driver has been in the CVS for months now, did anybody test

Yes, I did!
It works pretty good, I only got som problems when starting
lcd4linux. After starting via a rc-script the display stays
sometimes blank, the process is running, so you have to kill
the process and start it again by hand. After this everthing
works fine.
I use it on my firewall, to display the load, the current IP
and the time.
> If anybody out there has another T6963 display, I'd like to generalize

What a pitty, I only have a Samsung display, it is a
dot-matrix, the display is a 0150Z from Samsung.
(on the mainboard are 4 Oki M5299A, 2 Oki M6598, 
1 chip labeled with UG-32P(or F)03-BCBN8-C94091063
and some passives)
Does anybody knows if it will work with lcd4linux?

The lcd4linux with M50530 worked fine with a AMD K6 400MHz.
