Location of TSLIB(libts.so) and QT PLUGIN(libqtslibplugin.so)

Sidii

Dear SGaist, thanks for your reply. It seems it is a serial device. Is it possible to get the x,y coordinates from the screen and then map it to the QT Screen so that i can know what button is clicked? I have done serial programming in QT for GPS devices, but i have no idea of mapping to the Framebuffer to know what widget is getting touch.

Just give me some pointers so that i can think in that direction.
Thanks :)

SGaist

Didn't you succeed configuring tslib ?

Sidii

no because there is no dedicated driver, it is a serial device :(

SGaist

How does the system see it ? /dev/ttyS0 or something like that ?

Sidii

yes you are correct, also i found that when i do
@cat ttyS1@

then some junk characters are printed on putty terminal whenever i touch the lcd.
But i am not able to see x,y coordinates. I think some baud rate mismatch is there.

SGaist

hexdump will give you a cleaner output.

Well, AFAIK, setting TSLIB_TSDEVICE to /dev/ttyS1 should get you started, no ?

Sidii

I tried setting the same:

@
export QT_QPA_PLATFORM=linuxfb
export QT_PLUGIN_PATH=/home/Sid/plugins/generic
export QT_QPA_GENERIC_PLUGINS=tslib
export QT_QPA_FONTDIR=/home/Sid/fonts
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/Sid
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/ttyS1 -------->>SEE THIS
export TSLIB_PLUGINDIR=/home/Sid/tslib_plugins
export TSLIB_CONFFILE=/home/Sid/ts.conf

@

But when i run ./ts_test, i get no output :(
The program keeps running without any output unit i give Ctrl+C

SGaist

Did you run ts_calibrate first ?

Sidii

Yes, no output from ts_calibrate also..

Sidii

and if i do

@./ts_print@

i get following output:

selected device is not a touchscreen I understand

SGaist

Which module are you using ?

Sidii

Sorry i did not get you. Module??

SGaist

Sorry I meant tslib plugin

Sidii

I downloaded TSLIB (tslib-1.0) from sourceforgenet. And then crosscompiled it for powerpc. and then modified qmake.conf to include soure and libs. Also test lib test was successful.

I copied libqtslibplugin.so to plugins/generic folder.

SGaist

Not the Qt tslib plugin, the plugin from tslib itself

unfortunately I followed this conversation but there is no fruitful outcome that any one can follow:
