Which 7 inch touch screen ?

[Toine45]

I have received my aliexpress touchscreen

When i type getevent -lt /dev/input/event2
I can see coordinates, perfect !
I have created an idc file in /system/usr/idc but nothing moves :'(
VID : 266e
PID : 0101
Vendor_266e_Product_0101.idc
In this file :
touch.deviceType = touchScreen
touch.orientationAware = 1
device.internal = 1
keyboard.layout = qwerty
keyboard.characterMap = qwerty2
keyboard.orientationAware = 1
keyboard.builtIn = 1
cursor.mode = navigation
cursor.orientationAware = 1

Seem to be this product : http://www.singwaytouch.com/En/Product-2.html

Did you modify the multi-touch driver in Kernel as described on our Magazine Feb issue?

[Toine45]

Yes, my egalax resistive touchscreen works.
If i see coordinates with get event, kernel is ok.. right ?

[Toine45]

My mistake, the touchscreen works now ! multi touch works, coordinates looks ok, but the scroll with 1 finger seems not working :'( Do you have a solution ?

[Toine45]

So here's the problem :
Scroll with 1 finger don't works
AND when i click with one finger that's seems to push multiple time in really low time , example : if i use the virtual keyboard i press the F touch : i get FFFFFFFFFFF written in 1ms
Maybe a problem of sensibility ?
Best Regards

Hi, Toine45
Did you manage to fix the problem? I'm having exactly the same problem (not on ODROID actually, but on MK908II HDMI TV-stick).
I have added touchscreen's VID and PID in hid-multitouch.c file, recompiled the kernel. Touchscreen works, but with single finger I can only "click". Can not click-and-hold and can not drag (scroll). With two or more fingers everything seems to be OK.
The behavior is the same with or without idc file.
