how to install elo touchscreen driver

saman_artorious · 02-23-2013, 08:08 AM

i need to install elo touchscreen driver on an intel series panel pc. i do not have any idea whether to install the driver from elo download link as it only supports kernels 2.4 and 2.6! it is better to do that in ubuntu 11.1, is there any way to do that? the serial touch is connected to serial port and it gives me data when I touch the screen.

you have any idea what i should start doing at all?

Two issues really. Getting serial to work and getting it calibrated.

The connection is the most easy. It is basically a serial mouse. Some jumpers inside the screen usually were what configured how it attached. WARNING, removing a CRT back panel exposes you to VERY LETHAL voltages even with the ac plug removed. Also an implosion hazard.

The calibration is a different animal.

I am writing this for those having the same problem. this could be a straightforward quick guide to
installing the driver:

http://who-t.blogspot.fi/2012/07/elographics-touchscreen-

Code:

setup.html

Code:

root@localhost:~> modprobe elo
root@localhost:~> inputattach -elo /dev/ttyS0 --daemon

Code:

# cat /lib/udev/rules.d/99-elographics.rules 
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS1", \
        RUN+="/sbin/modprobe elo", \
        RUN+="/usr/bin/inputattach -elo /dev/%k --daemon"

Code:

# cat /lib/udev/rules.d/99-elographics.rules 
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS1", \
        RUN+="/sbin/modprobe elo", \
        RUN+="/usr/bin/inputattach -elo /dev/%k --daemon"
# cat /etc/X11/xorg.conf 
Section "InputClass"
	Identifier	"calibration"
	MatchProduct	"Elo Serial TouchScreen"
	Option	"Calibration"	"3568 507 529 3548"
EndSection

Code:

# cat /etc/hal/fdi/policy/10-elographics.fdi 
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.category" contains="input">
      <match key="info.product" contains="Elo Serial TouchScreen">
        <merge key="input.x11_driver" type="string">evdev</merge>
        <!-- next line is equivalent to an xorg.conf.d statement of
                Option "Calibration "96 4000 96 4000" -->
        <merge key="input.x11_options.calibration" type="string">3580 500 521 3468</merge>
      </match>
    </match>
  </device>
</deviceinfo>

next install the display calibration package n calibrate the screen. then
add the calibration X Y values to the xconfig file. no matter you do not have xorg.d folder in ubuntu 11.1 just
make xorg file as following:

Code:

# cat /lib/udev/rules.d/99-elographics.rules 
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS1", \
        RUN+="/sbin/modprobe elo", \
        RUN+="/usr/bin/inputattach -elo /dev/%k --daemon"
root@Safilan:/home/safilan# cat /etc/X11/xorg.conf 
Section "InputClass"
	Identifier	"calibration"
	MatchProduct	"Elo Serial TouchScreen"
	Option	"Calibration"	"3568 507 529 3548"
EndSection

if you have any problem maybe I could help.
