I don't think this is related to gcc, but your header files. system.c 
includes if_ppp.h, which triggers this error. Maybe one needs to inclode 
some other header before if_ppp.... If you take a look at the 
crc-ccitt.h file, at line 6, what is there "before const"? Next, try 
where this symbol gets defined, and try to include this file manually.

btw, you could and should try the CVS version of lcd4linux. The code is 
stable, it just lacks documentation...

The problem is, that due to the new layout (based on the evaluator), the 
corresponding layer in lcd4linux where liblcd4linux and the python 
bindings based upon is no longer present.

As we were facing lots of problems with libtool, too, I decided to 
deactivate liblcd4linux temporarily.

The new internal layout of lcd4linux uses very basic hardware display 
access functions; all of the special functions that various displays 
provide (GPIO's, contrast & backlight, fan reporting, ...) are 
implemented as 'plugins' to the evaluator. The display-specific stuff 
(drawing text, ...) itself is implemented as 'widgets'. Some displays 
need a regularly called timer function, too, which is implemented as a 
'timer' in lcd4linux, which is triggered by the lcd4linux main loop.

At the moment I have absolutely no idea where to find a common layer 
which liblcd4linux could provide to other applications. Yourt input and 
ideas are welcome!

But the only thing I see is the busy and the Load raw.

For example I want to see for new mails but nothing happen on my display.
I think that I forgot to tell the prog where to display it but I can't 
find any suggestions in the manual.
Here I post some things from my lcd4linux.conf:

No, I'm afraid it isnt:

The 'right way' would be:
expression (ppp('Rx:0', 500)+ppp('Tx:0', 500))

BUT the ppp plugin is somewhat broken: It takes a lot of CPU time, 
because it always triggers a modprobe for non-existing ppp devices. I 
don't know exactly why...

To be save, use the netdev plugin with the ppp device:
expression netdev('ppp0', 'Rx_bytes', 500)

It looks cool!

As for your other message, describing the display:

First, I'm shure the display itself is a HD44780 one. Therefore you 
could connect it to the parallel port as described on the lcd4linux 
homepage, and use the HD44780 driver.

The problem is the serial-to-display interface: The command set 
described in the docs is missing two important informations:

- how do I set the cursor position? There's only a "home" command 
described. But as the LCDKBD daemon supports such a feature, you could 
find out the command by sending it to this daemon, and watch the serial 
port (connect it to another machine or another serial port).

If you can't find out this command, lcd4linux could also do a "complete 
update" every time something changes. This is bad for speed and 
performance, but as the display is 16x2 only, this wouldn't hurt that much.

- how do I define a user-defined character? This command is necessary 
for bars. I'm afraid the controller does not support this command, 
because it's used nowhere. You won't get any bars without this command.

If you find the above infos, it should be quite easy to write a driver 
for this display. You could use an existing driver as a basis, and just 
modify the low-level functions for goto(x,y) and defchar(ascii, bitmap).


bye, Michael

RE: [lcd4linux] Revisisted > Help > Using LCD4Linux on Toshiba Magnia SG-20

[Simon K. <sim...@re...>]

Hi.  Here's some additional information about the LCD Display for the =
Toshiba Magnia SG-20.
=20
--- Simon.
=20
=20
=20
=20
LCD Panel Customization        =
<http://www.sos-spa.it/software/Immagine%20SG20/Magnia%20SG20%20General%2=
0Customization%20Guide.doc#B0000002> =20
=20


The Toshiba Magnia SG20 contains a built-in, easy to read and use LCD =
panel.  This display is normally used to present information to the user =
concerning the system status and operations.  Messages include items =
such as:=20

=09
*	Boot and shutdown progress=20
*	Backup / restore progress=20
*	Networking operations=20
*	Health alerts=20


The LCD panel and the items it displays are controlled by the internal =
operating system of the SG20.  Because the internal software controls =
the LCD panel, it is easy to add and modify what it displays.  No =
modifications to the system firmware are required.=20


This section covers a general description of the LCD panel operation, =
its interface, the software controlling message display, and how to =
display information on the panel directly without using the Magnia SG20 =
provided software.  There are two methods to interact with the Magnia =
SG20 LCD panel.  When using the Magnia SG20 preinstalled software, =
interaction with the LCD panel is direct, through the LCD daemon.  If =
using your own software preinstall image that does not include the =
Magnia SG20 software for LCD management, you can create your own =
programs and procedures to interact with the LCD panel and the system =
buttons.


LCD Interface Technical Overview


The Magnia SG20 contains two main boards.  The PC motherboard contains =
most of the controllers and interfaces normally associated with a PC, =
including the CPU, IDE controllers, serial and parallel port =
controllers, etc.  A second board, the mezzanine board, contains some =
additional components such as the internal built in Ethernet switch and =
the system LCD firmware.=20
=20
Communications to the LCD display are transmitted from the operating =
system software running on the main system board through the COM1 serial =
port.  The LCD controller firmware listens to the serial port and =
displays most characters sent through this serial port.=20

The LCD panel display is a two-line display.  Each line can display up =
to 16 characters.  =20


In addition to display and control of the LCD panel, the LCD firmware =
monitors and reports the button presses of the LCD select button and the =
soft power button, both located on the front of the Magnia SG20.


LCD Panel Direct Access=20


It is possible to interact directly with the Magnia SG20 LCD panel =
without using the supplied LCD control software.  This can be useful =
when a different operating system has been loaded on the SG20 (such as a =
generic Linux system, or DOS).=20


Please note that the techniques described in this section are for use on =
operating systems other than the one normally supplied with the Magnia =
SG20 by Toshiba.  The standard Magnia SG20 software contains a Linux =
daemon that controls and monitors the LCD and system buttons.  =
Therefore, attempts to control the LCD panel or receive button press =
information on the standard Magnia SG20 operating system installation =
will conflict with the LCD control daemon.

Direct LCD message display

Because characters sent to the LCD COM1 port are automatically displayed =
on the LCD screen, it is very easy to display your own messages.  For =
example, on DOS, the command:

	echo =93Hello World=94 > COM1=20
=09

Will cause the characters =93Hello World=94 to appear on the LCD panel.  =
The equivalen Linux command is:

	echo =93hello world=94 > /dev/ttyS0=20
=09

More complicated strings, controlling wrapping on the two LCD lines and =
spacing are available.  The following table shows the characters that =
are accepted for printing and formatting as part of the message text on =
the LCD panel.=20


	Received Character

	Name

	Operation

	 =09
	=91A=92-Z=92, =91a=92-=91z=92, =910-9=92

	ASCII printable code.

	Display character at the current cursor position and advance cursor to =
the next location. Scroll line as needed.

	 =09
	SP =3D =91 =91

	Space char

	Advance the cursor to the next cursor position and scroll as needed.

	 =09
	NL :=3D =91\n=92

	Newline=20

	Advance the cursor to the next line, scrolling as needed.

	 =09
	CR :=3D =91\r=92

	Carriage return

	Return the cursor to the first column on the current row.

	 =09
	ESC

	Escape

	Prepare for the next received char as a command code.

	 =09

=20


LCD Control Codes

In addition to direct transmission of characters to the LCD, there are =
several special command sequences that can be sent to the LCD =
controller.  These sequences are designed to ease formatting and =
manipulation of the LCD display.  All command sequences begin with the =
escape character, and are following by a character indicating a specific =
action.=20


The table below shows the available escape command sequences and their =
use.=20


Received Character

Name

Operation

=91H=92

 	 Home the cursor.

=91X=92

 	 Clear the display.

=91B=92

 	 Turn on backlight

=91b=92

 	 Turn off backlight

<sec>=91q=92

 	 Power down the system in <sec> seconds. Should only be sent at end of =
shutdown sequence.

Examples of the use of these commands appear below:=20


To send the LCD cursor to the top row, far left character position:

	echo =96n =96e =93\033H=94 > /dev/ttyS0=20
=09

To clear the LCD display:

	echo =96n =96e =93\033X=94 > /dev/ttyS0=20
=09

To turn off the backlight of the LCD display:

	echo =96n =96e =93\033b=94 > /dev/ttyS0=20
=09

To shut the power of the system off in 10 seconds:

	echo =96n =96e =93\03310q=94 > /dev/ttyS0=20
=09

Please note that issuance of the power off command illustrated above =
should not be issued unless the operating system is being shut down in =
an orderly manner. Sufficient time should be given for the OS to =
complete its shutdown procedures.

Button Status Codes

The LCD controller also monitors and reports whenever one of the control =
buttons on the Magnia SG20 is pressed.  These buttons include the LCD =
scroll button located directly adjacent to the LCD panel and the power =
down button located on the front of the Magnia SG20 and to the right of =
the LCD panel.=20


Button status information is sent in on the internal COM1 port.=20


Status values sent across the COM1 port are listed below.  No preceding =
escape or other characters are sent from the LCD controller to the =
motherboard.=20


	Transmitted Character

	Name

	Operation

	=91P=92

	Power

	Power button pressed.

	=91S=92

	Select

	Select button pressed.

Because these characters are sent across the COM1 port without a CR/LF, =
it may be necessary to write specific code to monitor the incoming =
characters.  This code should place the device in a raw mode in order to =
receive characters as soon as they are sent, so that they are not =
buffered.  While this can be accomplished using command line level =
instructions, it is significantly better to write a program to monitor =
and process these commands.=20


While command / shell scripts can be used to send information to the LCD =
for display with ease, monitoring and responding to button commands is =
best handled in a program specifically written for the purpose.


Magnia SG20 Queued LCD Message Interface


If you wish to add custom LCD messages when using a Toshiba Magnia SG20 =
preinstall, you need to integrate your messaging in to the internal =
messaging management system.  The internal queuing system manages the =
display of LCD messages, their positioning, translation and cycling =
through the multiple messages available for display using the LCD scroll =
button.=20


There is an LCD/KBD Daemon (LCDKBD) used to coordinate client =
application access to the LCD/KB micro-controller sub-system. This is a =
Linux daemon that runs at system startup and is used by client =
applications to queue messages to display on the LCD panel. Client =
applications do not directly communicate to the device.=20

Direct Command Line Interface

The command line interface to the LCD/KB port is used for direct display =
of messages on the LCD panel. The following describes the command line =
interface for script access.=20


setlcd [=96<cmd> [<data>]] <text>=20


Where -<text> is an ASCII text string with NL (=91\n=92) & CR (=91\r=92) =
support.

Where -<cmd> is described by the following:=20


Cmd

Description

Comment

-clear

Clear the display

Clear display and homes the cursor.

-home

Home the cursor.

Move to the row=3D1, col=3D1 position.

-home2

Move cursor to second row.

Move to the row=3D2, col=3D1 position.

-col <col>

Move the cursor to the column position

Move the col to <col>.

-row <row>

Move the row to the row position

Move the row to < row >.

 	  	  =09
=20


Note that because this command bypasses the message queuing system, it =
is reserved for use by the LCDKBD and for debugging.

Queued LCD Messages

Under normal circumstances, all LCD messages are displayed and managed =
by the lcdkbd daemon. This daemon takes messages that should be =
displayed on the LCD panel and places them in a queue.  Because there =
are multiple messages available for display on the LCD panel, the LCD =
scroll button on the front of the machine is used to communicate with =
the lcdkbd daemon. =20

When the lcdkbd daemon detects a button press, it will cycle through the =
various messages in the message queue.  Some messages can be forced to =
the top of the queue, placing the message on the LCD without requiring =
the user press the LCD button.  This technique is used for urgent =
messages such as alerts.  Messages can also be displayed for one time =
only.  This type of message appears on the LCD until the user presses =
the LCD scroll button, and is then removed from the message queue so =
that it does not appear again.=20


Use the Perl object ShowMsg to tell the lcdkbd daemon to display =
specific messages on the LCD panel, as described below.

Adding LCD Messages

Because the contents of the LCD display are managed by the lcdkbd =
daemon, display of new messages involves creating a new message =
definition in an LCD message definition file.  Once defined properly, =
the LCD message can be displayed on the LCD panel by sending the lcdkbd =
daemon an instruction.  Use the following procedure to add your own LCD =
message to the display message queue.=20


=09
1.	Go to the directory /sa2/lang/en/lcdmsg.  This directory contains all =
LCD message definition files for the English language (which is the =
default).  When customizing messages to display in different languages, =
go to the corresponding language directory, such as /sa2/lang/es/lcdmsg =
for Spanish, or /sa2/lang/de/lcdmsg for German.=20

=20


=09
2.	Create a new definition file for your LCD message.  An example of a =
new message definition file called =93newmsg=94 appears below:=20

=20


	newmsg.desc=3DAcme Application Messages

	newmsg.name=3DACME

	newmsg.readonly=3D0

	newmsg.hidden=3D0

	newmsg.msgup=3D-center =93Acme App=94 =96center =93Running=94

	newmsg.msgdown=3D-center =93Acme App=94 =96center =93Not Running=94

	newmsg.msgalert=3D-ontop -center =93Acme App=94 =96center =93%s =
Error=94

	newmsg.msgmail=3D-ontop -onetime =96center =93Acme App=94 =96center =
=93Check Mail=94=20
=09

	See the section below for more information on these fields and their =
operation.=20
=09

=09
3.	Add a Perl script to your application that invokes the messages =
defined in your LCD message definition file.  This script should =
incorporate the appropriate ShowMsg call to display a message.  An =
example program is shown below:=20

=20


		use SA;

LCD Message Display Options

The LCD message definition files contained in the /sa2/lang/en/lcdmsg =
directory contain a variety of options for the messages displayed.  The =
message definition file example given above outlines these options.  The =
fields and options contained in this file are described here by using =
this example.  Fields are defined by the name of the message with a =
specific configuration parameter suffix.  In the example above, the =
message name is =93newmsg=94, so the description field in this file is =
=93newmsg.desc=94.=20


	newmsg.desc=3DAcme Application Messages=20
=09

The =93desc=94 portion is the configuration field parameter indicating =
the text description of the LCD message.  This text description will =
appear on the LCD configuration page in the web administration user =
interface that allows the user to select which LCD messages they wish to =
appear.=20
=20
=20


LCD Configuration Screen=20


The name suffix provides and internal name used by the Magnia SG20 =
middleware to help identify the message being displayed or configured.=20


	newmsg.name=3DACME=20
=09

In this case, the name given to the message is =93ACME=94.=20


	newmsg.readonly=3D0=20
=09

The readonly field specifies whether the user will be allowed to change =
the LCD setting.  In the default LCD configuration screen, the IP =
address display, and time of day are always checked and cannot be =
unchecked by the user.  To allow the user to deselect this LCD message =
from displaying on the LCD panel, set the readonly field to 0.  To =
prevent the user from deselecting this message and force the message to =
always display, set the readonly field to 0.=20


	newmsg.hidden=3D0=20
=09

The hidden field specifies whether the LCD message appears on the =
configuration screen.  Some messages, such as health monitoring, do not =
even appear on the user LCD configuration screen, and are always =
displayed.  To prevent a message from appearing on the configuration =
screen, set the hidden field to 1.  To present the message on the user =
configuration screen, set the hidden field to 0.=20


	newmsg.msgup=3D-center =93Acme App=94 =96center =93Running=94

	newmsg.msgdown=3D-center =93Acme App=94 =96center =93Not Running=94

	newmsg.msgalert=3D-ontop -center =93Acme App=94 =96center =93%s =
Error=94

	newmsg.msgmail=3D-ontop -onetime =96center =93Acme App=94 =96center =
=93Check Mail=94=20
=09

A single LCD message can have several states, or sub-messages.  For =
example, the =93backup=94 message may present the backup status as =
=93Not Performed=94, =93Started=94 or =93Completed=94.  Only one of =
these messages can be displayed on the LCD panel at a time.  If the =
=93Started=94 message is displayed, and then later the =93Completed=94 =
message is displayed, the =93Completed=94 message will replace the =
=93Started=94 message.=20


In this example, the Acme App message will display =93Acme App=94 on the =
first LCD line.  The second line will be =93Running=94, =93Not =
Running=94, =93 Error=94 or =93Check Mail=94. =20


The following formatting options are available:=20

=09
*	-center: center the text in the middle of the LCD line=20
*	-ontop: immediately display this message by placing it on the top of =
the message queue=20
*	-onetime: clear this message from the LCD message queue after it has =
been viewed by the user once=20

The expression is wrong. Every plugin defines one or more _functions_, 
therefore there must be braces.

The POP3 plugin takes one argument, which is the number of the POP account.

In your case, the expression should read:

     expression POP3check(1)


HTH, Michael

[lcd4linux] Config-Sample for the pop3-plugin?

[<An...@t-...>]

Hello List.

I try to use the pop3-plugin and dunno how i can get it to 
work. I sucessfully put in username and password in the 
pop3_plugin-Section:

Plugin Pop3 {
   server1 'pop.t-online.de'
   port1 110
   user1 'An...@t-...'
   password1 'hehehe'
}

and get back starting lcd4linux -vvv :

[POP3] 1 POP3 accounts have been succesfully defined

Now, how should the correspondenting widget should look like
that mysterius to me. Ive tried:

Widget Pop3 {
   class 'Text'
   expression POP3check
   width 5
   align 'R'
   update tack
}

Im sure it isnt true, since it didnt work and i also cant
imagine it will, but i really have no idea how that should
look.
Or am i on a totally false path that a widget is needed?

Thanks for an idea.

Regards,
Andreas

Strange. Maybe there's a bug in the DVB plugin? or the system call does

You'll have to wait for 0.10.1.

There are no disk stats in /proc/stat with 2.6, so the proc_stat::disk 
won't find anything, and always return 0.

With 2.6, you have to use the plugin 'diskstat'. Have a look at the 
lcd4linux.conf.sample, the diskstat entries are commented out, you have 
to deactivate the 'proc_stat::disk' lines and activate the 'diskstats' 
lines.

Off the top of my head, I can't.  I have just been writing plain text
for the moment, I write better that way.  I'll be working on
formatting/markup hopefully next week.

[lcd4linux] function naming changed in CVS

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

Hi there,

I jhust changed lots of function names in CVS to follow the plugin::name 
convention. This may lead to unusable configurations, so double-check 
your lcd4linux.conf for function names!

Furter, this is important for the documentation guys! If you already did 
a "grep AddFunction *.c" to get all plugins, please do it again.

If I have a look at the Status file, we're heading for 0.10 Real Soon 
Now(tm)!! There's one display driver missing (Beckmann+Egle), all other 
drivers have been ported, all plugins have been ported. But 
documentation is missing!

Anybody with a Beckmann+Egle "Mini-Terminal" out there? I need a tester 
for porting the driver....

Can anyone tell me how to write documentation? I didn't follow these 
discussions...

I *had* to migrate. Someone removed the devfs stuff from the i4l 
subsystem :-(

But be warned that CVS aka 0.10 is a nearly complete rewrite, which 
means that a) it's full of bugs and b) the configuration changed a lot.

If you need help, just let me know.

At the moment, there's no support for scrolling. You can specify more 
rows and/or columns than your display has, place widgets there, but the 
additional rows/columns will not be used by now. In the (hopefully near) 
future there will be some logic to move the fixed "display window" over 
the (larger) layout area. But this is not implemented.

What version of lcd4linux are you using? The Crystalfontz USB displays 
are supported with the CVS version only, IIRC.

[lcd4linux] CrystalFontz 634 USB

[Fridtjof B. <fb...@gm...>]

Hi
Did anybody get the CF 634 with USB [1] working with lcd4linux?
I'm using kernel 2.6.6 with usbserial/ftdi_sio and the LCD appears 
as /dev/usb/tts/0. 
With Speed 9600, only garbage appears on the screen. With Speed 19200 
and without any Speed setting, the LCD gets switched off completly (I 
have to unplug it to get it working again, but lcd4linux will switch it 
off again).
Thanks for any hints. :)

BTW: lcdproc works, so the display is not broken, but I'd prefer 
lcd4linux.

[lcd4linux] uptime plugin available in CVS

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

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi there,

I just coded and uploaded an 'uptime' plugin for NextGeneration aka
0.10. If you're using the anonymous CVS, you'll have to wait for about
24 hours until SourceForge got in sync.

short info:

uptime() : returns (first) value from /proc/uptime as a number
~           e.g. 1234.56

uptime ('format') returns a string wich can be formatted similar to
strftime():

%s : returns seconds (all of'em)
%S : returns secons from 00 to 59

%m : minutes (full)
%M : minutes (from 00 to 59)

%h : hours (full)
%H : hours (00 to 24)

%d : days (full)

anobody interested in weeks, months, years, ... ?

all other chars will be printed as they are.

see lcd4linux.conf.sample for an example.


(I hope the documentation guys are listening :-)
