    Unhappy how to do touch screen calibration for qtopia-core-opensource-4.3.2

    I am using qtopia-core-opensource-4.3.2 on ARM S3C2440 samsung SBC.

    I set up touchcrean as below:
    QWS_MOUSE_PROTO="LinuxTP:/dev/h3600_tsraw"


    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?
    thanks,
    raman

    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.
