[lcd4linux] Problem with CF635, it wants picoLCD

[K B <int...@ho...>]

I am having trouble getting my CrystalFontz 635 working. I did the 
configure, make, and make install with no problems, and got the sample conf 
copied to /etc/ (all files form CVS as of 2/7/07). Everytime I lunch it to 
try and get it working I get this:

[root@asterisk1 lcd4linux]# lcd4linux -Fvv
Version 0.10.1-761 starting
plugin_cfg.c: Variable minute = '60000' (60000)
plugin_cfg.c: Variable tack = '100' (100)
plugin_cfg.c: Variable tick = '500' (500)
[KVV] Using station 89
[KVV] Using default port 80
[KVV] Using default refresh interval of 60 seconds
[KVV] Default abbreviation setting: off
lcd4linux.c: initializing driver picoLCD
drv_init(picoLCD) failed: no such driver

Have any ideas? Also woundering if you know some of the commands that go 
with the CrystalFontz display?

Ok, today I tried to use the picoLCD with linux-2.6.18, but I get the
same "nothing".

I had a look at the sample code from ituner, and found that they use
usb_interrupt_write() instead of usb_bulk_write(). I changed this in the
lcd4linux driver too, and.... it works!

Now I've seen the "bar bugs" too, and I found and corrected the bug: As
you've stolen^Wadopted the code from USBLCD, there are two places where
a ASCII 0 (zero) is escaped by another zero. This is necessary for the
USBLCD, but not for your picoLCD. Removind this code, and all the bars
work correctly!

Unfortunately the SVN server is down at the moment, so I cannot chek my
changes in. But I will do so as soon as it is up again.

Re: [lcd4linux] Scrolling LCD

[Gary P. <gpo...@ra...>]

Michael,

An update from my side, I have to apologize for this but after updating 
my version of lcd4linux I never tried using the init.d script to try 
stop the process - just assuming I would need to do it manually - but 
today I tried starting it the way I have been but using the init.d 
script to stop it after each sleep period and so far it looks great.

So again I am sorry for wasting your time - but it has been a learning 
curve so thank you for a great piece of software.

Luis, this version was compiled for me.

thanks again

You can get rid of the error "removing stale pid file.." by removing the
pid file by hand.

And could you please double-check if there are no mor
lcd4linux-processes running after you killed it?

Hi All,

Ok so we have upgraded LCD4Linux 0.10.1-756M compiled for Bering UCLIBC

I have a script that run's
lcd4linux -qf /etc/lcd/1.conf
sleeps for 10sec
then kills all pids relating to lcd4linux
then runs the next display
lcd4linux -qf /etc/lcd/2.conf
continues in a loop showing various options

it looks great but I am still getting errors in my syslog file

Anyone have suggestions ?

Can someone please confirm that these keycodes are working for *all* CF
displays? I'm afraid they are not, so wi will fix one display by
breaking another one...

I'm not sure about this one. First, I think the exec() should fork() in
every case, otherwise there may be large delays which disturb other
stuff within the lcd4linux engine (timers, ...)

Probably it would be a better idea to integrate this "one-shot exec"
into the existing exec() plugin.

What do you think?


Thanks for your contribution!

No, I don't think so. lcd4linux has been designed to be completely
independant from the size of the display.

Sorry, there are no fading effects now. As soon as we have some dynamic
layouts, there may be something like fading, too.

Just checking the website it seems that the serial 632 does not offer this
function, but they do make a special lcd that is supposed to offer that. So
it makes sense to get these errors, I guess the documentation is not very
clear on this.

You are right, all these update speeds are in milliseconds. So a value
of 1000 should give you an update every second.

using 'tick' and 'tack' ist just a trick: tick and tack are 'variables',
which are initialized on startup (you should have a 'variables' section
in your config file)

note that these two are the same

variables {
   tick 1000
}
widget any {
   ...
   update tick
}

and

widget any {
   update 1000
}

You are using the 632, right? After having a look into the code, it
looks like the 632 does not have any GPOI's configured (both values are
set to zero). If you could tell me the number of GPI's/GPO's, I'd modify
the driver.

Also it is unclear how to slow down a widget, I have played with the
different speeds, the documentation is also not clear on what exactly the
tick and tack do, and what the update is for. I understand it is in
milliseconds, but it does not seem to work as advertised. For example the
widget cpuinfo fly's across my screen, and I have tried to slow it down but
it does not seem to work. If I try to use the gpo widget, I get this when it
tries to run the test.

Crystalfontz::GPO(1): GPO out of range (1..0)
Crystalfontz::GPI(1): GPI out of range (1..0)
Crystalfontz::GPO(4): GPO out of range (1..0)
Crystalfontz: gpio_draw(1): GPO out of range (0..0)
Crystalfontz: gpio_draw(1): GPO out of range (0..0)

Also if you run lcd4linux in interactive mode how do you quit out of the
mode? The man page does not show the proper technique to stop it.  I have to
kill the process to make it stop. ctrl C, or ctrl X, just seem to be std
output.

This is with ubuntu amd64 edgy

I would like to get get this working I am willing to test setups, and
layouts but something seems to be wrong.

I was curious if anyone had some insight about this problem, seems that the
serial displays are really not in use much. I understand that the
CrystalFontz usb uses a usb to serial driver, but I am unsure about the
serial aspect.

[lcd4linux] new function 'decode()'

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

Hi there,

I just added a new, probably handy function to the evaluator:
decode(index, ...)

it takes a variable number of parameters, at least 2. the first one is
interpreted as an index, and the function returns the n'th parameter.

some examples:

decode(-1,'a','b') => '' (empty)
decode(0,'a','b') => 'a'
decode(1,'a','b') => 'b'
decode(2,'a','b') => '' (empty)

decode(3, 'a','b','c','d','e','f') => 'd'


It may be used to reduce nested '?' operators


I've got two questions here:

- is 'decode' the right name for it (there's a similar function in
Oracle's PL/SQL)

- is 'plugin_math' the right place for it?


enjoy, Michael

Well, I have no idea, but Nicu already reported some strange behaviour
with bars. I cannot tell without a real display, but I'm looking forward
to receive one from iTuner :-)

Oh, don't look for scrolling because there is none :-)

In fact, we are thinking for quite a long time about scrolling, changing
layouts and stuff, bit it has not yet been implemented.

Hi Gary,

This Version is quite old, and I'm quite sure it suffers from the bug
that exec'ed threads never get killed. But this has been fixed in SVN.

Is it possible for you to download and install a new version from SVN?

Killing the main thread will not help. Maybe you could check if 'killall
