Hello friends,

I have a board ads5121e with mpc5121 processor and Qt Embedded for linux. I want to use ELO 1715L touchscreen with my qt applications.

When i connect the touchscreen over usb, Linux recognizes it as a HID device automatically.

But the problem is that;in my Qt application , the cursor position does not point where I touch on the screen. I mean that; when I touch upper part of the screen, mouse cursor goes a bit more upper; when i touch lower part of the screen, mouse cursor goes a bit more lower than the touched point.. There is a mapping problem i think...

I guess that the resolution of the touchscreen and the resolution of the application are different.. Any idea how to solve that issue? Or is that a calibration issue? If yes how

I also tried tslib and use the touchpanel by serial connection(since there is already a driver in the kernel for my touchscreen). But i couldn't manage it(Thats another story...)

Any little idea is appreciated..
Thanks in advance...
