Re: touch screen does is calibrated

[Masaki Muranaka]

Hi,

Unfortunately, there is no ts_calibrate support on recent versions of
Android-x86.
Possibly you can calibrate by writing something in Vendor_14e1_Product_6000.idc,
but I don't know details. Please see documents provided by AOSP.

Have anyone idea which parameter in idc can swap axes?

Hello

[Somebody]

There is a touchscreen calibration UTILITY (Programs menu, application called "Calibrate" with a red/white bulleseye icon) for this in 4.4 RC2.

You need to add your product name to init_tscal function
of /system/etc/init.sh.
The product name could be found in
/sys/class/dmi/id/product_name

Thank you. It works!

After this change the calibration is working....do you know why isn't the calibration enabled for all device by default?

Not all touch screen need calibration.
Actually most modern multi-touch devices
don't need it.

/system/etc/init.sh:207
function init_tscal()

I have one notice - second (and next) calibration made touchscreen useless - it can be caused by screen in landscape which I have rotated between tries.

I have added it. Thanks!

How did you do the second calibration?
Try to run TSCalibartion again. Does it work?

[Roman Košnar]

While I use the device it had a small offset....so I tried run calibration from menu again. At this point the screen was rotated to landscape. The calibration didn't work this time. I think it inverted one axis. I can't test it right now.

Hey there 

i have a problem with my scd t7 touch screen it wont calibrate 

i tried

 

You need to add your product name to init_tscal function 

of /system/etc/init.sh. 

The product name could be found in 

/sys/class/dmi/id/product_name 

but the ...dmi/id file is emty

Hi Chih-Wei,

considering that Android-x86 purpose and application is to be used on x86 tablets, x86 laptops with native touchscreens,

but also applicable to generic desktops or industrial mainboards with USB touch monitors or standalone USB touchscreens, that may need calibration, 

like the ones used in Videopoker cabinets or Public Administration "Touch-Points" ( !!! but that applications is boring compared to videogames !!! :-) ,

I'd like to propose the attached patch to support USB touchscreens.

The patch modifies init_tscal() function in init.sh, in order to add an additional for...do...done loop to perform the scan of USB devices to check for specific USB touchscreens.

The device needing calibration can then be added in the case , like an old monotouch MicroTouch I have, whose identification ID is 0596:0001

Since invocation of calibration procedures is only needed once in init_tscal(), I added a return to leave init_tscal() as soon initialization has been done for a matching PRODUCT or for a matching $usbts.

Tested successfully on my monotouch MicroTouch Systems.

...

Now coming to David's problem, SDC-T7 is not a tablet or a laptop product having a TS, but it is a 7 inch monitor with embedded USB touchscreen, isn't It?

If that's the case, you should identify the ID of your touchscreen by following this easy procedure:

1. switch to command shell by pressing ALT+F1

2. unplug usb cable of your SDC-T7 (7 inch monitor+touchscreen, correct?)

3. plug usb cable again and you'll see IdVendor=XXXX and IdProduct=YYYY, this codes can also be extracted using Windows OS (VID and PID)

4. The ID of your device is XXXX:YYYY (replace with the alfanumeric strings you'll see at step 3.

David, can you provide the ID of your SDC-T7?

NOTE: ID codes of USB devices are catalogued here: http://www.linux-usb.org/usb.ids but I was not able to find your device in the usb.ids register.

Thank you for the patch.
It's a good idea to add the support of usb touchscreen.

I just modified the patch to avoid
duplicate code to create pointercal
and pushed it.
