eGalax touchscreen calibration

[ph87]

Hello guys,

finally I've got make it work on my Multitouchscreen (same type as you can get from chalc-elec [10"]). While swiping the pointer is a bit laggy but it works great with a Touch-skin where you don't have to swipe

At first this is not my work!!! Nearly all scripts and hints were made my brantje and Markamc (thank you very much for your very good and fast support!)
-Thank you very much!!!!

So that is what you have to do (this worked for me):

Terminal

wget https://github.com/brantje/xbian-touch/raw/master/install.sh

sudo sh install.sh

stop uimapper
stop xbmc

wget --no-check -O uimapper.tar.gz "https://docs.google.com/uc?export=download&id=0B4lrG9aRe-8MWXUtaktRbWVFdDA"

sudo mkdir -p /scripts && tar -zxvf uimapper.tar.gz -C /scripts

Next step:

Terminal

evtest

No device specified, trying to scan all of /dev/input/event*
Not running as root, no devices may be available.
Available devices:
/dev/input/event0: Chicony USB Keyboard
/dev/input/event1: Chicony USB Keyboard
/dev/input/event2: N-Trig Pen
/dev/input/event3: N-Trig MultiTouch
/dev/input/event4: N-Trig Touchscreen
Select the device event number [0-4]:

And keep the event numbers for Mltitouch and Touchscreen in you mind (for me 3 & 4)

Now open uimapper.conf:

Terminal

sudo nano /etc/init/uimapper.conf

Edit it as shown:

Terminal

#!upstart
description "uimapper"


env UIMAPPER_DEV="/dev/input/event3" <-------- Put in here your event Number for Multitouch
env UIMAPPER_CONF="configs/multitouch.py" <-------- change to multitouch.py
env UIMAPPER_DIR="/scripts/uinput-mapper"

start on (input-device-added SUBSYSTEM=input)

stop on input-device-removed

nice -10

kill timeout 1

expect fork

script
chdir $UIMAPPER_DIR
exec ./input-read.py $UIMAPPER_DEV -D | ./input-create.py $UIMAPPER_CONF &
exec ./input-read.py "/dev/input/event4" -D & <--------Add this line with your event Number for Touchscreen

end script
respawn

Now we have to reduce the tine for the touch-events (it's a capacitive touchscreen so it's more sensitive):

Terminal

nano /scripts/uinput-mapper/input-create.py

and change a value at nearly end of the script:

Terminal

if inrange <= 400:
if holdtime > 0.02 and holdtime <= 0.50:

Okay that must be all...
Now just run:

Terminal

cd ~
sudo sh install.sh

What is the event number of the touchscreen? eg: event0 then you type 0, followed by [ENTER]

Type always the event Number of the Multitouch which you have in your mind and follow the instructions on the screen. Sometimes for me the install.sh showed the wrong event Number and also you can't really recognize which one the Multitouch is - don't know why!
Calibrating does only work with the event Number which I've mentioned above...

Hope this works for you ----
