RE: eGalax touchscreen calibration
My evtest:
Code:
/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
/dev/input/event5:      uimapper - touchscreen

My /etc/init/uimapper.conf
Code:
env UIMAPPER_DEV="/dev/input/event3"
install.sh
Code:
XBian touch installer by brantje
Already installed... Recalibrating
Listing event devices
lrwxrwxrwx 1 root root 9 Jan  1  1970 usb-Chicony_USB_Keyboard-event-if01 -> ../event1
lrwxrwxrwx 1 root root 9 Jan  1  1970 usb-Chicony_USB_Keyboard-event-kbd -> ../event0

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

calibration does only work with 3 neither with 2 nor 4...
install.sh has still no effect...



When you want some Information please tell!!! Maybe I've confused you and did something wrong...

I thank very very much for your help!!!

RE: eGalax touchscreen calibration
when you select event 5 in evtest can you get any output for touchscreen ABS_X and Y?

can you see in evtest which event gives feedback for touchscreen ABS_X & Y, when uimapper is stopped, is it event3?

RE: eGalax touchscreen calibration
Yes, if uimapper is running it grabs 'exclusively' the event you have in uimapper.conf, in your case event3.

Your output from evtest (uimapper event5) seems to change the ABS_X/Y etc, but not the (ABS_MT_POS)

See what the values are for top left and bottom right for the ABS_X/Y, these are the values that uimapper changes and xbmc uses, I still think the problem is that xbmc is grabbing the device and stopping uimapper from applying the calibration

RE: eGalax touchscreen calibration
Ok, so the values are good and uimapper is generating them, so I think we need to make xbmc grab the device and then maybe all ok

goodnight my friend

PM'd you with something to test

RE: eGalax touchscreen calibration
I wonder why uimapper isn't starting.

Edit:
marc, if i plug in an usb drive, and remove it, than uimapper is stopped.
Is there an way to keep it running?

Hi Branjte,

Uimapper will respawn and should pick event before xbmc does, i can get reconnected when I unplug and replug. Problem is once xbmc has grabbed a device it needs to lose it so uimapper can get it again. If the event number changes (i.e. with new device added) then this can pose a problem. I have rewritten some code for the conf file that auto-selects the eGalax event number, works for only one entry for eGalax though (sometimes on some distros there are more than one event no. listed for device). Fortunately only one event on xbian though.

See here...
http://markamc.cybaman.net/?p=50#comment-77

If you can see a way to mod the code then it would be good, once the calib is done , it only needs to monitor correct event for device. This latest uimapper.conf works for me atm, I am testing.

Possible Solution to make it work on N-TRIG Multitouchscreens
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 Blush

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 ----

Marc, the ui-mapper is updated? If so, then i will place a new package on git, or i give you access.

May i prestent: Touchfluence -> Please test it and report back =)

Yep, I made updates to uimapper.tar.gz to fix bugs when changing resolution (may have been a conflict with xbmc patch).
It should only be necessary to calibrate once, now scaling the calibration values to suit different screen modes...(again, for me at least!! always a disclaimer!)

Some optional additions to uimapper.conf if you use a Ntrig, or other Multitouch device with many event entries. As explained above by ph87

I'll give it a go later. cheers. mark

I made some changes to touchscreen.py, I have your mutlitouch.py config included in the new uimapper.tar.gz file so if you leave the conf file it should still work ok. I need to compare the two config files to see differences.

It might be laggy since its reading two events from the TS, maybe I can find a way to grab all events but not read, I will look into the 'grab' code?

Your TS is a much higher resolution to, maybe this makes a difference.

No speed improvements atm though, just bugs with resolution changes and calibration. Also been looking into PyPy for speed improvements, a little busy at work so I have less time atm.

I'll keep you posted...
