    Atmel maXTouch 7" inverted axis

    I recently purchased the following item on ebay:

    http://www.ebay.com.au/itm/181195109829

    Everything has gone well to install it however I am testing my setup using a laptop outside of my car first and i am getting inverted touch response on both x and y axis.

    (when i touch the bottom left it gets detected as top right and so on)

    I have googled and googled and see a couple other people having the same problem as I do but there seems to be no definitive fix for this issue.

    I am running Windows 7 currently on a laptop that has Intel HD 3000 graphics.

    I am going to try if Windows 8 behaves differently but was wondering if anybody ever fixed this issue themselves?

    I have also tried on a desktop running windows 8 with ATI 4800 graphics with the same result now. Hopefully someone has a solution to this.

    Touch controller shows up as:

    Hardware ID's
    USB\VID_03EB&PID_2128&REV_20::&MI_01
    USB\VID_03EB&PID_2128&MI_01

    Driver Node Strong Name:
    input.inf:Standard.NTamd64:HID_Inst:6.1.7601.18199 ::generic_hid_device:usb\class_03&subclass_01:usb\ class_03


    From this i see that it is just using some generic HID driver for windows. maybe atmel provides a specific driver for this product?

    Stupid question but are you sure your touching the correct side and or its not fitted upside down?

    From the pictures that were sent to me by tft_lcd it looks like i have moutned it the correct way up. I could mount it the other way but then it would jut out slightly. I cant believe there is no software to switch inversion of touch input...

    From the instructions and pictures sent to me by TFT_LCD i have done it the right way, i guess i could mount it upside down from what was told to me but i would much rather some sort of driver pack or something so i can keep it mounted the way i have done it (as it fits perfectly this way)

    My cheap touch-screen inverts the X axis and the Y axis until I run the configuration/calibration software utility to define the corners.

    When I run the basic windows calibration messes it up even more. I was hoping there would be some software with the driver to be able to invert axis or figure out to invert based on its calibration

    Try the Worcol touch driver and calibration tool maybe.
