Yes, they should, but since it is a 40x4 and therefore it has two controllers on one
board I presume they share the RS line anyways. There is no second RS pin on the
connection bracket.

Thanks for the advice, at least it saves up a config line.

Stefan ( geronet ) already picked up the issue but he has no further advice
other than to look what's happening with an osci. While I have a 60MHz
osci ( which should be sufficient ) I am not that familiar with the protocol
and timings so I don't really know what to look for. Any advice here ?

Right, that's what I figured. Since it is a 40x4 lines 1&3 are filled with
blocks. That issue got solved once I bought a new 20x4. Both Display
initialize correctly now, but th 20x4 only shows garbage and the lines 5-8
which are supposed to be shown on the 20x4 are shown on line 1-4 above
the original 1-4 definituin. I have taken pictures but I was hesitant to post
into the ML because of traffic issues.

That's not the problem.

Here is a link to the datasheet, but I'm afraid that ASCII definitions are not
covered :

http://www.anag-vision.com/avkat/av4040.pdf

However, when the Display shows garbage he flicks some weird ASCII characters
through it and I could clearly identify the ° sometimes. So I *guess* the Display
is able to produce it when properly triggered. Is there any other way to tell the display
what to show ?

Re: [lcd4linux] Ticket #25: Icons leaking memory

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

Hi there,

Oliver found a Big Memory Leak in the Evaluator, which should be fixed
in CVS. The bug was triggered by a 'update static' line in his icon
widgets; 'static' was taken as a variable name; evaluating variables
lead to a unnecessary malloc().

You can omit the 'size' parameter (IIRC) because LCD4Linux automatically

Yopu got two lines of blocks? Normally there should be only one (or line
1 & 3 on a 4-line display). This is how the display tells you "I'm ready
for being initialized".

Maybe it's a contrast problem? There are displays out there which have a
good contrast with the contrast hardwired to GND; but others really
require a resistor (or better a potentiometer). This would explain the
two black bars, too.

Did you try to remove the enable lines of the other displays, and
connect the enable of your third display to one of the others?

Are you sure that your display has the degree char has 0337? I think the
octal stuff should work, although I'm not sure (I'm in the office at the
moment, and therefore cannot test). You could try any other ASCII value
(maybe just an 'a') just to make sure this works...

[lcd4linux] Ticket #25: Icons leaking memory

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

Hi Oliver,

thanks for reporting.

I tried this with the X11 driver (as its a graphical one like the T6963
which I don't have at the moment), and I couldn't find an increase in
memory usage.

Are you using the latest Release, or the current CVS version? IIRC
there's been a fixed leak somewhere around icons some months ago....

Could you please test the current CVS version? (If you need assistance
with CVS, let me know). If the problem is still there, please send me
your lcd4linux.conf.


Thanks, Michael

Very good point! As nobody complained, I'm going to change this, remove

Thanks for the hint! I just modified the "How to write..." stuff in the
wiki.

First, there's no need to keep two seperate dirs (one with the original,
one with your modifications): CVS does this job for you, and it allows
you to regularly update your local (and modified) copy.

To create a patch, run this command:

cvs -z9 diff -bu >your_patch.diff

gzip the file and send it to me...

Hi Michi.!

I think the function 'count' ist not necessarily, you can make the same with
an SQL-Query like this :

select count(*) from whos_online;

this will also return the number of rows from the SQL-query.

[lcd4linux] Plugin MySQL: rename of functions

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

Hi there,

yesterday I got a patch from Harald Klemm which adds a new function
'queryvalue()' to the MySQL Plugin. This new function returns the first
value of a query.

Now, I think the function names are a bit misleading: query() returns
the number of rows returned by a query; queryvalue a real value.

I think queryvalue() should be renamed to query(), and the current query
function to 'count()' or something....


any comments? Who feels "responsible" for the MySQL Plugin?

TIA, Michael

Right :-)

Sorry for not answering your question, I've been very busy.

But "scrolling" in the Layout is surely my next step in improving
LCD4Linux (as soon as I've finished the GPO's in all drivers)

So stay tuned!

Hi everyone,

Is there any possibility to scroll through virtual rows in LCD4Linux-0.10?
It was possible in older versions using Rows, Scroll and Turn options.
However the format of config file has changed since than and now I have no
idea how to make it working. Reading new Wiki did not answer this 
question :(

Any hint how to make LCD scroll through rows will be highly appreciated.

[lcd4linux] 3x HD44780 problem / special character problem

[Kamil W. <we...@ra...>]

Hi everyone,

after evaluating lcdproc, lcdmod, lcd-linux and lcd4linux I found lcd4linux the 
fastet and most sophisticated
LCD driving application of all of them. I especially like the softwiring, 
nevertheless I used "WinAmp" style
wiring the way lcdproc understands and soft-wired these settings in lcd4linux.conf.

So far so good. It works perfectly for a 40x4 Anag Vision A4004 Display ( Conrad ) 
with two KS0066 controllers.
Until here I appreciate all your work and time you put together to build lcd4linux.

Then I got high-spirited and tried to wire up a third 20x4 HD compatible LCD. In 
order to do so I salvaged the
the third enable line (EN3) by disconnecting R/W from the 40x4 ( and connecting that 
to GND ). The 40x4
share the RS line, both have D0-D7 connected and each controller ( 2 on the 40x4 / 1 
on the 20x4 right ? )
has its own enable line.

I configured the whole thing like this :

Display HD44780-40x8 {
     Driver      'HD44780'
     Model       'generic'
     UseBusy     0
     Bits        '8'
     Port        '/dev/parport0'

     Controllers 3

     Size        '40x8'
     Size1       '40x2'
     Size2       '40x2'
     Size3      '20x4'

     Wire {
     RS          'INIT'
     RW          'GND'
     ENABLE      'STROBE'
     ENABLE2     'SLCTIN'
     ENABLE3    'AUTOFD'
     BACKLIGHT   'GND'
     GPO         'GND'
     POWER       'GND'

    }
}

Is this correct, theoretically ?

I believe so, but the practical result proves me wrong. The 20x4 won't even intialize.
I only see two lines of blocks. I can't be completely sure, that the 20x4 display 
isn't broken
since it isn't new but an older one salvaged from a display project some time ago.

If anyone has any advice I would appreciate it very much. Otherwise I'll have to buy
a new one next week to eliminate the possibility of a broken display / controller.

---

The second issue is the usage of the i2c plugin. It's a great plugin and I emerged
lm_sensors to feed it properly. Again, it's working out of the box using the example
provided.

Since I sit in Germany and I like our °C trailing any temp degree value I wanted to add
a postfix to get something like CPU: 34°C. After doing so my whole layout got
screwed up. I searched the archives and found something about using \337 the octal
value of the ASCII character, but that didn't work out as well.

Any suggestions regarding that matter will also be gladly appreciated.

Thanks a lot in advance and keep up the good work.

Hey, great idea!

coded, checked int CVS, documented in the wiki (look for 'SIGNAL_POWER'
and 'T_POWER'.

who said there's slow development cycles with lcd4linux?

[lcd4linux] Powering the HD44780 from the Printer Port

[Mark E. <mj...@po...>]

In Reference to Directly Connecting a HD44780 Compatible LCD to a
Parallel Printer Port....

As far as I understand - it should be possible to power most displays
from the power given by the LPT Printer port. I'm not referring to the
back-light - just the display itself....

In order to do this - one would need to "Switch-On" one of the Control
Output pins first - before trying to initialise the Display.

By using the "BACKLIGHT" wiring command - I can get power to the LCD -
but this seems to happen AFTER the LCD has initialised.... which is then
a bit late... - ie - The display stays blank.

Any chance of a modification that first Powers up (eg a Pin called
"POWER") - and then sends all the initialisation stuff???

It should then be possible to then Power and Drive an LCD from only the
Parallel port.

I'm pretty sure you forgot to set a variable in drivers.m4, probably
"graphic=yes" or something.

You could try to omit the '--with-drivers=...' parameter, so that all

No, it won't. Have a look at configure.in and search for
"has_serdisplib". There should be a macro or function or something that
tests for serdisplib and sets this variable accordingly.

Re: [lcd4linux] new lcd4linux driver / problem with last CVS checkout

Hi Michael,

hm, i see in drivers.m4 that serdisplib use: if test "$has_serdisplib" =
"true"

so i thought lcd4linux will do the work for me.

Re: [lcd4linux] Re: new Driver

Hi Michael,

thats only an bitmap that i load to second graphic screen and on first screen i set the lcd4linux widgets.
The bitmap was not from me, i take it from bigwig from casecontruction forum.

With libluise i can set the gfxmode 0 = or / 1 = and / 2 = xor, i set xor and place the widget with Row/Col.
I can also invert the screen or set rotation. 

Most work will be done by lcd4linux and libluise and not from me.

When the driver is done i'll make an nice picture ;)

Hmm.... you'll have to fight with autoconf. Take a look at configure.am
and drivers.m4. Some of the drivers require a library ind a include
file, too. Look for "libusb" or something...

But be warned: This ist complicated stuff.....

Did you try a 'make clean' before?

If you have all the autoconf/automake stuff installed, try a './bootstrap'.
