A Qt app for tracking mouse/touchscreen pointer movements.

Used to evaluate a BeagleBone Black touchscreen.

Assuming Qt5 dev libraries and headers are already installed.

Build natively

$ qmake && make


The UI places 5 buttons along the top of the screen.

You can test with a real USB mouse connected or by using the touchscreen directly.

Run under X11

Make sure you have calibrated the screen with xinput_calibrator first.

$ export DISPLAY=:0.0
$ xinput_calibrator

Then run the app

$ export DISPLAY=:0.0 (if not already set)
$ ./tspress

Run without X

$ ./tspress -platform linuxfb -plugin evdevtouch
