hi,
let me change the question. i have a serial touch screen interfaced to /dev/ttyS1 . how to enable it in qt-embedded-3.3.5 ?
in the configure option i saw options for USB touch screens (touch screens connected to /dev/input/event0).but there were no options for serial touch screens. i gave "-qt-mouse-linuxtp" in the configure option and export the environment variables as follows:
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts
export TSLIB_TSDEVICE=/dev/ttyS1.
and
export QTDIR=/usr/local/qt-embedded
export QWS_MOUSE_PROTO=linuxtp:/dev/ttyS1
when i execute a qt application , the touch screen did not work and the mouse pointer disappears the moment i touch the touch screen. the following error is displayed :
"Could not read calibration: /etc/pointercal".
any suggestions or solutions for this ?

No, there is no such file in the /etc folder in the board.
Then maybe you should create one?Quote:

Google says something about ts_calibrate utility. Do you have it?
hi ,
yeah i searched about that. and it says to use tslib package. i had done that also. the main problem for me is that i had my device connected to "/dev/ttyS1" and the ts_caliberate.c program is used to caliberate the device connected to "/dev/input/event0". can you say me how to convert that with respect to serial port ? if you have any docs for that can you send me ?
Did you find any success in this?
