Touchscreen calibration on linuxfb embedded application
I have a BeagleBone Black board with a BB-View touchscreen display.
Now I have Qt 5.3 on my board and I can build and run Qt applications this way:
./styleexample -plugin evdevtouch
The problem is that the touchscreen pointer is not very accurate.
I know that for Xorg there is xinput_calibrator but it doesn't works for non X systems.
Is there a way to get TS more accurate in linuxfb mode?
I actually found a workaround:
./styleexample -platform xcb &
This way I have a calibrated touchscreen (I calibrated it before with xinput_calibrator).
But I'd like to have the TS working in linuxfb platform...
If this is a resistive, single touch only touchscreen, you could try using the tslib plugin instead of evdevtouch.

Running apps with tslib plugin the TS doesn't works... I don't know why.
