LDCproc - get i2500vfd working

[n0s3]

Hey guys,
sorry for bad english - i am not a native speaker :/

i need help modifying the current (2.3.3-DEVELOPMENT (amd64)) LCDpro package to work with my Intranator 2500 Display.
i got some input from revengineer (https://forum.pfsense.org/index.php?topic=110177.msg688692#msg688692) but i think a new thread would be better. I need alot of help :D
my usbconfig output:

ugen0.5: <vfd display="" intra2net="" ag=""> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (0mA)</vfd>

goal:
i want to use my Intranator 2500 Display on my pfsense setup.

What i did:
As i understand LCDproc (http://lcdproc.omnipotent.net/hardware.php3) i need driver i2500VFD.
unfortunately that driver is not avialable through the LCDproc php interface, so i changed /usr/local/www/packages/lcdproc/lcdproc.php and added an i2500vfd driver entry to the dropdown menu:

$driverGroup->add(
        new Form_Select(
                'driver',
                'Driver',
                $pconfig['driver'], // Initial value.
                [
                        ...
                        ...
                        'i2500vfd'     => 'i2500vfd',
                        ...
                        ...
                ]
        )
);

But if selected and try to save the config via php interface, no /usr/local/etc/LCDd.conf gets created… seems to have problems with my changes -> ?? where can i find log files?

then i tried to directly modify /usr/local/pkg/lcdproc.inc and write 'i2500vfd' directly in to the LCDd.conf
i changed:
$config_text .= "Driver={$lcdproc_config[driver]}\n";

...
$config_text = "[server]\n";
                $config_text .= "DriverPath=/usr/local/lib/lcdproc/\n";
                $config_text .= "Driver={$lcdproc_config[driver]}\n";
                ...
                ...
 \"\n";
...

to

...
$config_text = "[server]\n";
                $config_text .= "DriverPath=/usr/local/lib/lcdproc/\n";
                $config_text .= "Driver=i2500vfd\n";
                ...
                ...
 \"\n";
...

now the /usr/local/etc/LCDd.conf gets created and the i2500vfd driver is selected… but my display does nothing (execpt showing the Intranator logo, as usual). I read somewhere that the driver i2500vfd needs to be selected during compile time of the package.??

what should i do next to gets this working.
any help even reading material would be great.

Regarding your lcdproc.inc modification, scroll down that file a little bit further to where all the case statements for drivers are, and add a case for i2500vfd:

			case "i2500vfd":
				$config_text .= "[{$lcdproc_config['driver']}]\n";
				break;

That will enable your UI change in lcdproc.php to select the i2500vfd driver, and you won't have to worry about that switch statement failing and executing the line: unset($lcdproc_config[driver]);

If you do it that way then undo your previous lcdproc.inc changes

I read somewhere that the driver i2500vfd needs to be selected during compile time of the package.?

This was what I was worried about, I'm not very familiar with the lcdproc drivers but the help suggested a dependency and your tinkering seems to be confirming it.

The pfsense LCD package uses Freebsd's lcdproc ports package, which is built by this makefile, and that makefile contains a FTDI option to "Build drivers using libftdi", but I don't know what the implications would be to add that dependency to pfsense's LCDproc package.

You could look into installing/recompiling a version of the sysutils/lcdproc ports package with the FTDI option on your pfsense machine, then your driver-selection UI changes might start working. I'll leave advice on how best to make changes like that to people who use FreeBSD as their day to day OS.

That driver is not being built from what I can see. It's not in the make file at all and if you look in /usr/local/lib/lcdproc, it's not there.

Just adding it as selectable is not going to help. You will need to compile it yourself on an equivalent FreeBSD machine and import the .so driver file to test it.

If you check the system log after attempting to start LCDd it will probably show errors.

Hey,
today i setup a FreeBSD VM in my qemu. But again i have problems and need help.

I tried to build lcdproc on my own. (including i2500vfd)
I downloaded the sources and tried to build it with following command:

./configure --prefix=/root/lcd/bin/ --enable-drivers=i2500vfd

the prefix thing is just for me, i want to know what gets installed where :D never mind..
problem:

It seems that if i make it now, nothing will be maked. Yes i installed libftdi package via pkg.

pkg install libftdi

After that same problem…
I decided to build the latest FTDI lib.
I cloned the latest master banch from git. Problem during prepareing:

...
...
...
-- Boost version: 1.63.0
-- Found the following Boost libraries:
--   unit_test_framework
-- Building unit test
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

    linked by target "ftdipp1" in directory /root/git/libftdi/ftdipp

-- Configuring incomplete, errors occurred!
...

due to my lacking cmake knowledge i cant help me…. :(

maybe some of you can help me...

Looks like you might need the "libftdi1" package, instead of the plain "libftdi"…

Best of luck, keep us posted.

Hey,
Thanks for the reply!
but i still cant get it to compile my needed driver…
I installed your suggested package (below prove of installation)

root@:~ # pkg install libftdi1
Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
Checking integrity... done (0 conflicting)
The most recent version of packages are already installed

but i still get:

root@:~/lcdproc-0.5.6 # ./configure --enable-drivers=all
...
...
configure: WARNING: The i2500vfd driver needs the ftdi library
...
...

anything else i can do?
i dont know what else i need to install…

I WANT TO USE MY DISPLAY SO BAD :D

You can try the attached. Took a bit of convincing around pkg-config, but it compiled. I do not have the LCD, so I have no idea if it works.

Disclosure: The attached file is an i386 binary that could technically contain "any"code, and I suggested you install this code (of unknown origin to you) into a security-focused live system. You probably should only do this into an off line home system you fully own and control…

$ ldd server/drivers/i2500vfd.so

MD5 (server/drivers/i2500vfd.so) = 8ce01a45856be894d9a8c2cf30363e10

I had to install a couple of things:

# pkg install libftdi1
# pkg install pkgconf

Then I ended up with:

configure CFLAGS="$(pkg-config --cflags --libs libftdi1)" --enable-libftdi --enable-drivers=i2500vfd

Best of luck, keep us posted.

Hey, long time no see…
i still did not get it to work.
I tried your file with no success. :( but thanks for the offer anyway!
I guess your file is not working because of 32vs64 bit?

so i am back to compileling myself.
I did a fresh freebsd 10.3 VM setup and tried to replicate your steps:

# pkg install libftdi1
# pkg install pkgconf

then configure with ur call:

root@freebsd-vm:~/lcdproc-0.5.7 # ./configure CFLAGS="$(pkg-config --cflags --libs libftdi1)" --enable-libftdi --enable-drivers=i2500vfd
Illegal variable name.

but i get illegal variable name…

so i try to fix that by modify the parameter:

i dont know how to fix this.

any help would be nice

I used this:

./configure  CFLAGS="$(pkg-config --cflags --libs libftdi1)" --enable-libftdi --enable-drivers=i2500vfd

Then

$ make

Results in:

Check if the attached works for you. Let me know.
