View Full Version : how to do touch screen calibration for qtopia-core-opensource-4.3.2

4th December 2007, 21:17
I am using qtopia-core-opensource-4.3.2 on ARM S3C2440 samsung SBC.

I set up touchcrean as below:

The touch screen works when I run example applications such as "calulator",
but it has not been calibrated and so "Press 9" actually hits "5".

I run "mousecalibrate" application, however it does not help.

Does anyone know how to do touch screen calibration for qtopia-core-opensource-4.3.2?

Thanks in advance.

Have you been able to find a solution to this.I am not able to calibrate the touch screen here.Can you list out the steps used for calibrating the touchscreen?
I am using Qtopia4.3.5 here.I am able to run display applications on the target.I have found a mouse calibrate code in example code section.Are there any example codes for calibrating touchscreens?

I have got the same board. But it works with Tslib driver. If you can't calibrate it, it is a good idea to check raw coords that the application or driver returns. Then you can translate these coords to your screen coords in driver's source code.
