Tslib with dirverless usb touch module
-
Hi,
I have a 'driverless' USB capacitive touch module. On a PC I plug it in and it works under Linux and Windows. It also works on my embedded device (i.MX6) under xorg, but not under QT with -qws
The touchscreen behaves like a mouse and I have no Idea how to fix it.

hi DasBasti,
Does you configure enviroment for Tslib working correctly?
you should check what your device(touch screen) are recognized by linux PC ? and configure for tslib can understand. By using command ls /dev/inputIn my case, that is event0.
@export QWS_MOUSE_PROTO=tslib:/dev/input/event0
export TSLIB_CONSOLEDEVICE=none
export TSLIB_TSEVENTTYPE=INPUT
export PATH=/sbin:/usr/sbin:/bin:/usr/bin
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_PLUGINDIR=usr/lib/ts
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export LD_LIBRARY_PATH=/opt/qt-arm/lib:$LD_LIBRARY_PATH@Try it and give response :)
happy coding with Qt -
Hi and welcome to devnet,
What version of Qt are you using ?
Did you setup tslib properly ?
Do you have any error message when starting your application ?

hi RyderQt
I tried to use your configuration values. ls /dev/input gave me two event inputs (0 and 1) The USB tochpanel is connected to event1.
So I have changed QWS_MOUSE_PROTO to "tslib:/dev/input/event1 Auto" to get it back working at all.
The behaviour si still the same. The Touchpad behaves lke a trackpad or like a mouse. I can move the Cursor back and forth but the curser moves way faster than the finger on the tocuhpad. I think there is something wrong with calibration maybe?
when I run ts_calibrate I get the error that the device is not a touchscreen, but it does calibrate something

tslib: Selected device is not a touchscreen (must support BTN_TOUCH events)
