Hello there, I have a E2014T dell touch monitor and I am trying to use it in pair with BeagleBone Black. The touch module is connected using usb cable. I have read in this tutorial: http://embedded.von-kannen.net/2014/05/21/qt-4-8-6-on-beaglebone-black/#comment-4288 How to enable the tslib and touchscreen. But I think, that this reffers to a touchscreen not connected to the usb, because it doesnt work.
Without adding those variables to enviroment: $ sudo nano /etc/environment -> add the following lines QWS_MOUSE_PROTO=tslib:/dev/input/event0 TSLIB_CALIBFILE=/etc/pointercal TSLIB_CONFFILE=/etc/ts.conf TSLIB_PLUGINDIR=/usr/lib/ts -> Save (Ctrl + O) and exit (Ctrl + X) $ sudo reboot Touchscreen works out of the box, but it is not even close to being calibrated. The offset is really big and it changes when my finger is in different part of the display. After enabling the: QWS_MOUSE_PROTO=tslib:/dev/input/event0 Touchscreen stops working. I feel like its not event0 at all. When I run ts_calibrate and try to press the crosshair, it doesnt work. It feels like touchscreen is off for the ts_calibrate program. Does anyone has any expirience in such usb touchscreens and BeagleBone Black? I Would really aprichiate some help. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
