Hi all...

   today I finally got qt4.8.4 compiled and running on my olinuxino board with A13-LCD7-TS...
I've spent some time trying to understand why my calibrated-mouse handler (I'm not using tslib) didn't work... and it results that X and Y positions returned by the /dev/input/eventn interface where larget than expected... between 0 and 4000... is this normal ? I was expected to get X/Y in the range 800x480 or similar...

anyone knows the resolution of the TS7 touchscreen ?

   best regards

Hello Lub

   are you talking about the LCD resolution or the resistive-touch resolution ?

        thanks in advance

Hey Giampaolo,

I'm talking about both. Can't find a place in the TS's documentation stating that the resolutions is higher than 480x800. The dimensions are also 7'' for both and both the display and the TS fit perfect togetjer.

hello Lub

thanks for your clarification... I don't know why (maybe a bug in my code)... but the linux input subsystems seems to give me coordinates in the range 0-4000... anyway, it's not a real problem, just a matter of rescaling.
