calibrating Elo touchscreen - ubuntu 9.10 or 10.4

[ahoros]

I am having tough time connecting my external Elotouch intelitouch monitor to Dell latitude D420 laptop.
(via USB)

That is kernel is properly detecting the device - however the coordinates are reversed.
e.g. up is down and right is left

I have found examples how to configure it via xorg.conf -- however I belive that under recent version of x.org that file is not used anymore.

Moreover the utility for calibration does not work:
root@wali:/etc/X11# ts_calibrate
ts_open: No such file or directory


I tried both 9.10 and now I am struggling with 10.4 --- with no success.

I would appreciate any pointers - anything that I was able to google on the web seems to be outdated.

Thanks

[ahoros]

I guess the question is should I try to install additional drivers for xorg
and try to configure it via xconf.org -- as most sites suggest (albeit for older version of kernel / xorg)

or is there any way to pass arguments to kernel
since it seems to be doing OK job of detecting the elo touch screen:

some people suggested passing arguments to HAL (for instance: "wacom.fdi" in /etc/hal/fdi/policy) --- but no HAL anymore in 10.04 ...... and anyway I have Elo.

Still need help! --> how to calibrate touchscreen

direction reversal problem is solved - but the screen still needs calibration - on the right hand side of the screen the mouse movement to actual touch area is off by about 1 centimeter!

The tslib calibration library seems to be still broken despite 10.4 final status )-:

[Interruptor]

I've made this [quick and ugly] script to calibrate "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U"

device_id=$(zenity --entry --text="`xinput list`\n_________\n\ndevice id:")
minx=1000
maxx=3655
miny=960
maxy=3314
errors_status=""
while `zenity --question --text="$errors_status\n___\n\n$minx,$maxx,$miny,$maxy\nAg ain?"`; do
minx=`zenity --scale --text="min-x" --value=$minx --min-value=500 --max-value=1100 --step=5`
maxx=`zenity --scale --text="max-x" --value=$maxx --min-value=3200 --max-value=4000 --step=5`
miny=`zenity --scale --text="min-y" --value=$miny --min-value=800 --max-value=1100 --step=5`
maxy=`zenity --scale --text="max-y" --value=$maxy --min-value=3000 --max-value=3600 --step=5`
errors_status="`xinput --set-prop "$device_id" "Evdev Axis Calibration" $minx, $maxx, $miny, $maxy 2>&1`"
done
For sitting: 1000,3655,970,3325

[Noob Programmer]

Thanks so much for that calibration script. I had to change the min and max values past what you were allowing.
min-x 50
max-x 3990
min-y 50
max-y 4080

[Interruptor]

Detection of device id:

device_id=`xinput list | grep Touch | grep -o "id=[0-9]*" | sed 's/id=//'`

[Interruptor]

Just found http://sourceforge.net/projects/evcalibrate/
Can someone test it and post returned values here?
Because I will be able to test it myself only in 2+ days.

If it's working, then we can mark thread as solved.

[Favux]

Hi,

On this elo thread (http://ubuntuforums.org/showthread.php?t=1483778&page=3) dglnz used touchcal (http://touchcal.sourceforge.net/) to calibrate.

[Interruptor]

Yeap, evcalibrate working perfectly.


$ sudo ./evcalibrate /dev/input/by-id/usb-Elo_TouchSystems_Inc._Elo_TouchSystems_IntelliTouc h_2500U_07U01964-event-mouse
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axis Calibration" 32 990 3686 936 3341
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axis Inversion" 8 0 1
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axes Swap" 8 0
So, 990 3686 936 3341 for 17" IntelliTouch 2500U

Just had to make and run it under root and installed next packages before compiling:

libqt4-opengl-dev
qt4-qmake

I think this should be added to first post and thread marked as solved.

Favux, thanks, but touchcal is not my case:

Supported Hardware
------------------
- EloGraphics(R) IntelliTouch E281-2310 (serial)
- MicroTouch(R) SMT3 (serial)

No USB touchscreens are supported at this time, but patches to support
different configurations and new hardware are very welcome.

Firstly this has been the most useful thread for solving my Elo touchscreen calibration issues, kudos.

I am trying to calibrate an Elo TouchSystems 2216 AccuTouch USB Touchmonitor Interface, and I cant use any of the aforementioned calibration tools. I am building this for an embedded system I do not have OpenGL, (there goes evcalibrate), its a USB touchscreen (c-ya touchcal) and Gawd help me if I can get the framebuffer to play nice so ts_lib is not working either. However thanks to you folks I have been able to solve the inverted axis issue, and through trial and error I am closing in on the min and max for X and Y.

The issue that I still have is the one that ahoros mentioned in an earlier post.

I am actually a bit farther off the mark than ahoros, the cursor is approx 2 inches off from where I am touching the screen. I've looked at the available options under xinput

Not sure which of these options I need to use. set-ptr-feedback looks the most promising but what values to use? Any help is greatly appreciated thanks.

[kqr2]

This thread has been very informative. I was able to fix the axes / swap issues and calibrate using evcalibrate.

Another question: does anyone know how to enable a beeping sound on touch / click events?

It looks like the elo driver has the beep capability, however, I would like to stick with evdev since it's working now.

I'm a bit of a newbie to compiling on Ubuntu, trying to get my touchscreen working on an old eeePC, can you help me out?

Here's what I have done so far:


sudo apt-get install qt4-qmake
sudo apt-get install libqt4-opengl-dev

I have downloaded evcalibrate, and identified my PATH-TO-NODE-EVENT and the code I would use(once in my extracted evcalibrate directory) would thus be:


$ sudo ./evcalibrate /dev/input/by-id/usb-eGalax_Inc._Touch-event-mouse

The place I am lost with is what you said here:



Just had to make and run it under root


Can you (or anyone) tell me line by line by that actually means and how I do that?

Thanks in advance...

Have you successfully compiled evcalibrate?

If not:

* extract evcalibrate:

tar xvzf evcalibrate-0.5.1-r1.tgz

* in evcalibrate directory:

qmake
make

* you should then be able to run evcalibrate

It looks like you don't have gcc installed. Make sure you have build-essential installed.

sudo apt-get install build-essential

Then try make again.

Great, I did that and it seems to have installed correctly, and entering qmake then make seemed to successfully compile as well. I feel like I am so close.. but still no cigar as yet:

You had a copy and paste typo. You typed "$ sudo ./evcalibrate" ... no $; just:

sudo ./evcalibrate ...

If you are already root, e.g. # prompt, you can just do:

./evcalibrate ...

[lymchan]

One step forward, two steps back...

So you were right, getting rid of the typo did get evcalibrate to activate, and I get a "preparing touchscreen for calibration..." screen showing. Unfortunately that's all I get, it just hangs there.

So I thought, maybe I should check that my touchscreen is still detected. It used to be (ever since Lucid NBR install) that when I hit anywhere on the screen the cursor moved/clicked to the upper left corner. After running evcalibrate, it does so no longer. Also, when I check dev/input, there is no longer a "by-id" folder, let alone my usb-eGalax-etc event file.

I am persevering with this dammit! If there are no other recommendations, I'll try to reload Lucid NBR (or just boot via CD) to see if that brings back the touchscreen detection.

Thanks again.

kqr2 saw that and tried it but it does not address my specific issue because I am not using the same monitor as the earlier poster. I have experimented with various numbers for min and max but there does not seem to be a linear relationship (i.e. more negative does not result in farther left)

I am also hoping that once I get the min and max right the pointer will correspond to where I am actually touching the screen and not roughly 2 inches off.

One step forward, two steps back...

So you were right, getting rid of the typo did get evcalibrate to activate, and I get a "preparing touchscreen for calibration..." screen showing. Unfortunately that's all I get, it just hangs there.

So I thought, maybe I should check that my touchscreen is still detected. It used to be (ever since Lucid NBR install) that when I hit anywhere on the screen the cursor moved/clicked to the upper left corner. After running evcalibrate, it does so no longer. Also, when I check dev/input, there is no longer a "by-id" folder, let alone my usb-eGalax-etc event file.

I am persevering with this dammit! If there are no other recommendations, I'll try to reload Lucid NBR (or just boot via CD) to see if that brings back the touchscreen detection.

Thanks again.

O, sweet, that looks exactly like what I need. Thanks so much, this whole "get help from complete strangers from indeterminate location" thing is still pretty new to me, I hope to be able to return the favour somehow :).

I know I'm kind of on my own out here but I figured out what worked for me and thought I'd post it just in case anyone ever found themselves in the same situation.

I ended up using a trial and error approach to finding the proper calibration parameters. When initially turned on the X axis was inverted so I had run the xinput set-int-prop etc to correct the inversion and had been trying to calibrate from there. It turned out that in order to get the screen calibrated I needed to undo the axis correction on X and invert Y!!! Which seems a bit weird but it worked for me. I then created this script to run at startup to calibrate the screen


#!/bin/bash

# This script is used to calibrate the touchscreen at startup

`sudo xinput set-int-prop 5 228 8 0 1`
`sudo xinput set-int-prop 5 229 32 2750 1050 2850 1050`


sudo was needed because the kiosk does not run under root.

Also if you do

xinput -list

it lists all the devices, my touchscreen was device 5, much easier than typing the complete name of the device!

Thanks again for the help

Be careful, device id can change if you connect or disconnect any input devices. I had this problem and solved it by this script:

device_id=`xinput list | grep Touch | grep -o "id=[0-9]*" | sed 's/id=//'`

Hey guys,
it seems as you are a step further with your ELO problems than I am.
I am trying to get my ELO 1715L Touchscreen working on a ubuntu 10.04-machine. The Display itself works, of course, but none of the touchscreen-function.
Which drivers are you using? The official ELO drivers are for older kernel versions only, and I couldn't find any working installation guide.
Thanks for any help and advices...

Yup you were exactly right, moved the flash to another machine and the id changed. Duh, sometimes I out smart myself! Thanks for the script.

I am stuck in the same situation. The numbers don't seem consistent with the actual alignment. I almost got there but at the same time, when I touch other parts of the screen, it seems way off again. Any suggestions?

Interruptor,
Quote from your notes:
"
So, 990 3686 936 3341 for 17" IntelliTouch 2500U

Just had to make and run it under root and installed next packages before compiling:
Quote:
libqt4-opengl-dev
qt4-qmake
I think this should be added to first post and thread marked as solved.
"
Could you perhaps help me by explaing how to:
"Make" it. I have noticed in the document:
http://touchcal.sourceforge.net/
it tells me to make it but after untar the files into one folder, I do not know what to do to start the calibrater:

I have: Ubuntu 11.04 and a 1939L Elo screen

Your help/assistence/pointers would be appreciated very much.
