Well, shame on me, but at the moment there's very little time for
lcd4linux. My son (who is getting 14 months these days, funny how time
flies!) and my real-life job is eating all my time, and I try to cath at
least a few hours of sleep every day (I know this is wasted time, but...
on the other hand, there may be some good drugs outta there :-)

I don't think that the current CVS/SVN is ready for a new release (maybe
I'm wrong, and I should follow the "release early, release often" advice)

Can you tell me what exactly is the problem with GCC-4.1? Maybe I could
just fix these bugs in the stable branch....

Hmmm.... I think this is the same question as with the wiki: I think if
I close it, there will be far less traffic (it's already (too) low
traffic I think)

Speaking for myself, if I want to report a bug or something similar to a
project, and I need to be subscribed, I wont. But as always, YMMV.

[lcd4linux] problems with first line on 20x4

[Leszek100tka <ha...@10...>]

Hello,

I have a 20x4 lcd display (of course hd44780), my config looks like something 
here below (I know that it should be written in a different way, but now i 
really dont know how:):


Widget Load1 {
    class 'Text'
    expression loadavg(1)
    prefix 'Load: '
#   postfix loadavg(1)>1.0?'!':' '
    width 10
    precision 2
    align 'L'
    update tick
}

Widget Load2 {
    class 'Text'
    expression loadavg(2)
    prefix ' '
    width 5
    precision 2
    align 'L'
    update tick
}


Widget Load3 {
    class 'Text'
    expression loadavg(3)
#    postfix loadavg(1)>1.0?'!':' '
    width 5
    prefix ' '
    precision 2
    align 'L'
    update tick
}


Widget Eth0r {
    class 'Text'
    expression (netdev('eth0', 'Rx_bytes', 500)/1024
    prefix 'Rx: '
    postfix ' '
    width 10
    precision 0
    align 'R'
    update tick
}

Widget Eth0t {
    class 'Text'
    expression (netdev('eth0', 'Tx_bytes', 500)/1024
    prefix 'Tx: '
    postfix ' '
    width 10
    precision 0
    align 'R'
    update tick
}



Widget Uptime {
    class 'Text'
    expression uptime('%d days %H:%M:%S')
    width 20
    align 'R'
    prefix 'Up '
    update 1000
}



Layout L20x4 {
    Row1 {
        Col1  'Uptime'
         }
    Row2 {
        Col1  'Load1'
        Col11 'Load2'
        Col16 'Load3'
         }
    Row3 {
#       Col5 exec('cat /home/hardtmuth/my_files/temp_temp/lala, 1000)
         }
    Row4 {
        Col1 'Eth0r'
        Col11 'Eth0t'
         }
}

Display 'HD44780-generic'
Layout 'L20x4'
Variables {
   tick 500
   tack 100
   minute 60000
}

and the problem is that there is something wrong with the first line on LCD. 
Now I have on the first line 12:07 some spaces and at the end of the line 
6:03:15 (counting up - its uptime). I see that its really messed up, because 
there should be up days 0 6:03:15.

When i`ve uncommented Row3 / Col5 with that exec formula, the uptime line is 
displayed correctly. 

Why there is some connections between I and III line? sometime i`ve noticed 
that when i start lcd4linux, the display looks good, then i restart lcd4linux 
and first line is messed up.

Next i`ve problem with reading data from file, i`ve temperature in one file. 
I`m trying do read it with exec and cat, no results only some garbage:

sh: -c: line 1: syntax error near unexpected token `)'
sh: -c: line 1: `cat /home/hardtmuth/my_files/temp_temp/temp_raw.txt, 1000)'
exec error: could not read from pipe 
'cat /home/hardtmuth/my_files/temp_temp/temp_raw.txt, 1000)': Success

and doing this in a different way, by file::readline, i get:

Evaluator: unknown function 'file::readline' in 
<file::readline('/home/hardtmuth/my_files/temp_temp/temp_raw.txt', 1000)>

what am i doing wrong? Should I pass when i was compiling lcd4linux arguments 
with plugins to include or by default all plugins are compiled in?

Sorry for huge post, but i think that posting in one huge post is better that 
few smaller :).

Thanks for help.

Well, the underscore should be a standard ASCII char, so I don't
understand why it should not be displayed correctly.

Have you got a datasheet for your display? Normally a character map is
part of the documentation, have a look at it...

btw, how do you access the environment variables? is there a 'getenv()'
plugin? If not, any volunteers to write one?

What does 'lcd4linux -Fvvq' report?

when turning on power to the display, do you get one black bar? Does
this black bar disappear when you start lcd4linux?

Yes, all our displays use the busy flag. Currently we have an really
evil hack which greps in syslog for "timeout waiting for busy flag on
controller" and terminates lcd4linux if found. as said, really evil.

Yes, I found that in the code. In principle, I could perhaps insert some
exit(1) statements at some strategical point, but that's really hackish,
and I wanted to consult this list before doing that.

Well, as usual, that depends.

If you don't use busy-flag checking, the communication is pure
unidirectional, and there's no way to detect wether there's a display
connected or not.

If you use the busy-flag, there's a possibility to read back at least
some status information from the display. LCD4Linux uses this to test
wether the display can accept a new command or not.

At the moment there's kind of a fallback, which means that if the
busy-flag check fails several times, the HD44780 driver goes back into
normal unidirectional mode (using some worst-case delay values).

But I'm afraid this check won't be sufficient: normally the display is
that fast (or the parport is that slow) that the first 'check-busy' test
reports the display as idle. And a successful busy check is done by
testing some signals for logical 'high' (or 1), which is the default
state if the pin is not connected (there's sort of a 'pull up resistor'
built into the parallel port).

I'll have to dig into the HD44780 specs to find out if there's another
possibility to check for a connected display. We could implement such a
test into the code (if there is one).

[lcd4linux] Presence detection of HD44780 display?

[Reinhard T. <sir...@ta...>]

Hi List,

In our appliance, we have 2 variants: one with an HD44780 display and
some machines without. I'd like to have some mechanism in lcd4linux,
which makes the daemon exit gracefully when there is no display on the
paralell port.

Does lcd4linux offer something like that?

Right, because the 'co' command will never ask for a passwort, but the
'login' command will.

The documentation on the wiki says:

LCD4Linux's CVS repository can be checked out through anonymous
(pserver) CVS with the following instruction set:

cvs
-d:pserver:ano...@lc...:/cvsroot/lcd4linux login

cvs -z9
-d:pserver:ano...@lc...:/cvsroot/lcd4linux co
lcd4linux

When prompted for a password for anonymous, simply press the Enter key.


So you have to issue the 'login' command first.

Re: [lcd4linux] How to get started with lcd4linux

[Robert D. <ro...@he...>]

Understood on the no time to migrate thing.  It is difficult and time  
consuming to migrate repos I know.  I tried using the command line  
cvs client but kept running into password prompts. sf.net offers anon  
access but I couldn't quite work that out so... For the sake of this  
list and future googlers here is what I did:

rsync -av rsync://lcd4linux.cvs.sourceforge.net/cvsroot/lcd4linux/* .

This worked out much better for me than CVS, and I got all of the  
files in the repo without complaint, except... All files were  
downloaded with ',v' appended to the filenames!  So here is the one- 
liner I used to deal with that:

perl -e 'foreach $old (glob "*,v"){$new = $old, $new =~ s/,v 
$//;rename $old, $new;}'

Getting it to configure is a different story.  I am still working on  
that.  Right now I am getting errors indicating my 'missing script is  
either too old or missing'.

Any ideas what that means?

We are planning to switch to SVN on trac, but I couldn't find the time

Well, I don't like the idea of tarballs, because they're out of date as
soon as they are created :-)

Please get yourself a CVS client and use the CVS repo. Basic CVS
handling should be the same as with svn.

Hi,

Looking through the CVS repos on sf.net, I see that there are many  
many files that have been updated in the last few weeks, and last few  
months. I am curious why you are not including all of this stuff in  
the subversion repo in your trac pages?  I work with svn on a daily  
basis and it would be a simple matter for me to tarball all of the  
current files (for anyone's benefit not just mine) if they were all  
in there.

I am not as adept with CVS, indeed I don't even have an CVS client  
handy.  Any plans to put your project in subversion?  And how  
troublesome would it be for you to tarball the current working set  
for me to use?

Re: [lcd4linux] How to get started with lcd4linux

[Robert D. <ro...@he...>]

Hi Michael,

When you say use the CVS version, what do you mean?  I looked in the  
SVN repo in yout trac page and it seems empty, also the tarball I got  
was from sourceforge as I recall and you mentioned not to use that  
site, right?  Would you be so kind as to provide a link to the best  
tarball to use?

The last I looked, the SuSE RPM was for lcd4linux .9 and not the  
newer .10.  Thanks!

Ah, yes, I remember. The title page has been spammed yesterday...

This is a known bug, which is fixed in CVS. I'd recommend you to use the
CVS version anyway, cause some 635 issues have been solved there IIRC.

I'm a debian user, so I can't be of much help here.... but there's a
SuSE RPM (don't know if Fedora and SuSE RPM's are compatible) Don't know
if there are some "RPM sources" available in CVS....



bye, Michael

Thanks for the response Michael.  As it turns out I think the pharm  
spam is gone now so you must have found it. At one point there was  
nothing at all in the trac pages except links I was not interested in  
following, offering free [insert drug here].  Thanks for cleaning  
that up.

I got the .10 tarball and did a quick ./configure and a quick make,  
bu the make terminated quickly with this:

[root@localhost lcd4linux-0.10.0]# make
gcc -DHAVE_CONFIG_H -I. -I. -I.    -D_GNU_SOURCE -Wall -W -g -O2 -c  
drv_generic_i2c.c
In file included from drv_generic_i2c.c:76:
lcd4linux_i2c.h:81: error: array type has incomplete element type
make: *** [drv_generic_i2c.o] Error 1


Looks like I have some work to do ;)  As it happens I just got the  
unit with the LCD (20x4 Crystalfontz CFA-635) and I through Fedora on  
it very quickly with little thought to my eventual production  
environment.  I just wanted to see what cool things I could do with  
it.  Alas...

I will rebuild the unit in my typical gui-less build and try it again.

I am still interested in working with someone on putting together a  
Fedora RPM for lcd4linux, so if anyone wants to collaborate on that  
please let me know. More shortly.
