Hmm. I could think of two reasons: A timing issue, or a wrong wiring. 
Could you please double-check your wiring, and send me the output of
lcd4linux -F -vv

Your english is ok. At least I can understand you :-) (I'm from Austria, 
so my native language is german, too)

[lcd4linux] Hi. I've got a Question.

[Matrix1000 <Mat...@gm...>]

Hi have a HD44780 Display and want use it.
The Display is on /dev/parport0.
So I used the config Port /dev/parport0
but I only get trush on the display.
If I use Port 0x378 then the display becomes black. (clear screen)
Other Infos:
Size 20x4=20

Row1 "hello"
Row2 "hello"
Row3 "hello"
Row4 "hello"

I have no idea what could be wrong.
Please help me. :-)

Sorry for my bad english but I'm from Germany.

Re: [lcd4linux] lcd4linux on FreeBSD ??

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

> I just wonder if you could get lcd4linux to work on FreeBSD 4.6

I'm afraid I can not. Not because it isn't possible, but I don't have 
any *BSD up and running here (and I don't have any spare time or 
computers to install it).

Another reason would be a namespace conflict: Who would like to run a 
programm called "anything4linux" on BSD? :-)

I think a port to BSD should be possible. There are some areas in 
lcd4linux which I think they are very linux-specific (ppdev() for 
parallel port access for example, or the various clients, which make 
heavy use of the /proc filesystem).

But all of these could be solved.

Any volunteers? :-)

bye, Michael

I don't know if it's working. If the commands are similar, it should. 
I'm very interested in getting it to work, please let me know if you're 
sucessful. If you need any help, let me know.

Thank you, that helped a lot.

I think the problem is that 0.98 did not correctly deactivate rdtsc() 
when the corresponding include-file "msr.h" could not be found. This has 
been fixed in the CVS some time ago.

You could either

- use the CVS version

- try to find the file "msr.h" and copy it to /usr/include/asm/msr.h"

No, sorry, I'm not going to provide binaries.

What exactly is the problem? I suppose you get some error messages, 
which I need to know.

Maybe it's an odd problem with msr.h. This kernel file seems to be 
missing on some distributions, or is empty.

Hi,
I upgraded on kernel 2.4.10, and I've lost the binaries. I tried to 
compile it with this new kernel but it fails when it try to compile 
something like udelay.o
Where's the problem?

Re: [lcd4linux] writing to DDRAm

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

Hi Michael!

Sorry about the long delay in answering you...

I've written my own C++ class for the Powertip LCD(16 columns by 2 rows),
using alot of code from the HDxxx driver from LCD4Linux.  I have attached
them to this email.  Included is the header, source, and a quick
implementation of the class.

I know this code isn't the best, but it works.

If you've had any luck with the direct memory writing problem, please let me
know because the LCD is slowing the entire application down.

Thanks for your help.
Regards,
Carlos

What exactly are the problems you're facing with msr.h?

I have seen some problems out there, I suppose they come from the fact 
that some linux distributions deliver a wrong msr.h.

msr.h is included because I need the 'rdstcl()' symbol within udelay.c

Hi Chris,

Did you run 'configure' again after installing libgd? Maybe you'll have 
to remove 'config.cache' before.

The current version of Raster.c emits a little error message about how 
to solve this problem....

Re: [lcd4linux] gd.h not found

Christian,

I have a very similar problem with the msr.h file when compiling for use =
with Crystalfontz displays. My guess is that there is a data type =
mismatch or other anomaly in either the Raster.c or XWindow.c file that =
I am using. I have some notes from my experiences that I have posted =
below, maybe it will send you in the right direction.

Cheers,
Dave

---From my notes---

First, the configure process doesn't find the msr.h file, even if I =
specify a=20

path to look in so:

=20

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

=20

then while still in the lcd4linux-0.98 directory:

=20

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

rm -f Crystalfontz.c

mv Crystalfontz.d Crystalfontz.c

=20

#Thanks to Herbert Rosmanith for the above fix

=20

./configure

make

make install

=20

cp lcd4linux.conf.sample /etc/lcd4linux.conf

chmod 600 /etc/lcd4linux.conf                                         # =

What did you modify? Does it make sense to put the code into the

No, I'm sorry. I just wanted to know why you would like to write to the 
display RAM (but there is some code inside of HD44780.c which writes 
into the CGRAM to create user-defined characters. I suppose writing to 
the display RAM is similar...)

Hi Carlos,

You have to be more specific:

- what kind of display are you talking about? Which driver are you using?

- I think there's not much difference in sending one character a time or 
writing one byte to the display RAM.
