HS/FS Visu with Elo Touch 1515L

[Warichet]

Hi,

Someone managed to make an Elo Touch 1515L work with an Ubuntu 9.10 ?
If yes, maybe a hint about the driver, please ?

It works somehow, but the touch movements are eratic, and up-down movements are working in down-up direction (so, opposite).
It looks like the driver available on the Elo Site is made for older versions of Elo Touch.

Thank you.

Hi,

I have an 1545L which is older? It uses a serial connection. I had the same "functionality" like you have, at the beginning. Information about all this is very rare.

I found out there are (at least) 2 ways to support the touch.
1.) Using input driver and tslib --> I never got that working
2.) Using xf86-input-elographics driver.

The second option was working for me. You should use the newer X and xf86-input-elographics driver. I use xf86-input-elographics-1.2.3 and xorg-server-1.6.3.901. In the older version (I don't know the version number anymore) was a bug, that lead to a hanging X.

After installing everything you need to add something to /etc/X11/xorg.conf. In my case this is:

Section "InputDevice"
        Identifier "ELO touchscreen"
        Driver "elographics"
        Option "Device"   "/dev/ttyUSB0"
        #Option "SwapXY" "true"
        Option  "MinX" "4110"
        Option  "MaxX" "-16"
        Option  "MinY" "4133"
        Option  "MaxY" "25"
EndSection

and of course:

Section "ServerLayout"
    Identifier     "Main Layout"
    Screen      0  "Screen0" 0 0
    InputDevice    "Mouse1" "CorePointer"
    InputDevice    "Keyboard1" "CoreKeyboard"
    InputDevice    "ELO touchscreen"    <---- This one; rest may differ
EndSection

Now comes the difficult part. You need to calibrate the thing. You see in the first xorg.conf snippet the values for Min/MaxX and Min/MaxY. These are important. You see also that MaxX is much lesser than MinX. This fixes the opposite movement.
To find the numbers for your screen you can use trial-and-error or you can use a calibration program.

The calibration program came as source code. It runs in standard text mode and shows 2 crosses which you have to tip and then shows the values for the parameters.

Currently I have no access to my computer with the calibration program so if you still need the information I can have a look this evening ...

If you try tslib I would be very interested if you get that working. The nice thing of tslib is, that it allows to filter the touch information, which should give a better usability.

Hi Mike,

Thank you for taking the time and trouble to reply with all those details

Information about all this is very rare.

This is a very very kind way of saying a more abrupt truth.
I'm very angry about Elo and their Linux support, it's a mess !
My first attempt to use the 1515L as a HS Visu under XP was without any trouble, all fine, but it was just a feasability test. The final setup is under a fanless/diskless miniPC running Ubuntu.
I'm not going to recommend Elo for a Linux setup, don't do it unless you are a die-hard massochist.

Here is some feedback from Zorglub, a Linux specialist

I finally got the damn thing to work correctly, I used a different approach apparently my 1515L was not supported correctly by the Ubuntu package ”xserver-xorg-input-elographics” and I opted for the “xserver-xorg-input-evtouch” package. Ubuntu 9.10 (Karmic Koala) came standard with version 0.8.8 of the driver.

Unfortunately I could not calibrate the driver, I kept on receiving an error message when I launched “calibrate.sh” (see Ubuntu bug id 317094) after a few research it appears that I needed to create a new fdi file for the screen.

I used the output of “lshal” as well as the “50-elo-2700.fdi” that came with the package as template to create the fdi file and realized that the screen was identified as “Elo Touch Systems 2216” ?!?

Once the file created and the system rebooted, I could calibrate the screen using the application from the “System -> Administration -> Calibrate Touchscreen” menu. You also need to read the README.calibration that come with the package.

Another benefit was the creation of an input device “/dev/input/evtouch_event”
