touchscreen QTe

[damien]

hi,

I use a uClinux in a board BF548, I want to use a touchscreen with picture flow application (QT app).
I can calibrate my touch screen with ts_calibrate so i think it working.
I can execute ./pictureflow -qws to show in my LCD screen some picture.
but i can't use the touch screen in the pictureflow app and all the QT app.
do you know how can i use a touchscreen with QTe3.3.5.

I have configure QT with :
./configure -shared -depths 32 -no-cups -no-ipv6 -embedded bfin -little-endian -thread -qt-mouse-tslib -L /home/dam/blackfin-sources/TS/ -I /home/dam/blackfin-sources/TS/

my uClinux is build with TS

my env on my board is :
QWS_MOUSE_PROTO=tslib:/dev/input/event1
TSLIB_TSDEVICE=/dev/input/event1
TSLIB_CALIBFILE=/etc/pointercl
TSLIB_CONFFILE=/etc/ts.conf
TSLIB_CONSOLEDEVICE=none
TSLIB_FBDEVICE=/dev/fb0

could you help me

Some questions:

1.- are you patch QT embedded to add TSLIB support??
2.- When I configure QTe, I use the follow options:

export QTDIR=$PWD
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:/opt/tslib/lib
echo yes | ./configure -platform linux-g++ -embedded x86 -big-endian -no-cups -depths 4,8,16,24,32 -qt-gif -qt-libjpeg -qt-libpng -qt-zlib -qt-mouse-linuxtp -qt-mouse-tslib -L /opt/tslib/lib -I /opt/tslib/include -lts

best regards

P.D. Tengo ganas de irme a casa, que ya es hora.............

How can i patch QT with TS Lib please

[damien]

i need the patch of TSlib for QTembedded 3.3.5 where can i find it?

[kugar]

Tslib has to be configured properly on your device.
Can you run ts_test?
What is the conent of ts.conf file?

[damien]

hy kugar,
I can run ts_calibrate but ts_test
root:/> ts_test
ts_test: not found

this is my ts.conf:

# Uncomment if you wish to use the linux input layer event interface
module_raw input

# Uncomment if you're using a Sharp Zaurus SL-5500/SL-5000d
# module_raw collie

# Uncomment if you're using a Sharp Zaurus SL-C700/C750/C760/C860
# module_raw corgi

# Uncomment if you're using a device with a UCB1200/1300/1400 TS interface
# module_raw ucb1x00

# Uncomment if you're using an HP iPaq h3600 or similar
# module_raw h3600

# Uncomment if you're using a Hitachi Webpad
# module_raw mk712

# Uncomment if you're using an IBM Arctic II
# module_raw arctic2

module pthres pmin=1
module variance delta=30
module dejitter delta=100
module linear

Thank you for your help

Well,
you should have some Tslib test tools provided by tslib sources. They are very helpful:
ts_test - you can use your touch screen
ts_calibrate - calibrate your ts
ts_finddev - check if device is a ts
ts_print - print coords computed by modules from ts.conf
ts_print_raw -print raw coords
ts_harvest -don't remember
Maybe you should change input module. I use h3600. Default input does not work on my device.

hello
I can run ts_calibrate and “event_test /dev/input/event1" but the other test like ts_test or ts_print are not found, i don't know why?
I think that my touch screen running because i detect the event and i can calibrate it, but i don't found what is the configuration step of QT which isn't working

I haven't the file qmousetslib_qws.cpp in the qt-embedded/src/embedded/
I think this is the problème I haven't driver for TSlib in QTembedded.
can i had it?

[kugar]

If you configure Qt with -qt-mouse-tslib option then you must have Tslib driver somewhere. I think that your board has a Sharp's touch screen. Maybe you have to change raw module. By the way, I have got qmousetslib_qws.cpp in Qt/src/gui/embedded folder.

[damien]

hy,
thanks

I haven't qmousetslib_qws in all the qtembedded file.
can i find it? and is it difficult to configure for my hardware?

I have
