Android accepts abs events from input subsystem. You can check
omapzoom kernel ts driver for reference.

Hi all,
I am porting Android to a OMAP3530 LV SOM development platform. I am using a
tsc2004 touchscreen. I have built the 2.6.28 kernel and I can get Android to
boot however the touchscreen is not working. The touch screen is assigned to
event0. I can getevent and touched the screen and here is w

Hello Sun,
Thanks for reply
#define ADC_MAX ((1 << 12) - 1)
#define ADC_SCALE(x) ((x) * 640 / 4096) // scale down to 640 pixels.
I am using 640 X 640 screen.
But on another board ads7846 touchscreen gives the approximate same output

LCD resolution is 480x272 and Android view is in landscape mode.

Hi all,
Yes, tsc2004 touchscreen LCD resolution is 480x272 and Android view is in
landscape mode.
Has anyone tried or ported landscape LCD view based touchscreen on android.

What do you see in the Pointer Location app in DevTools? Does your event
stream from getevent look reasonable? What events is the driver saying it
generates?

I don't know how to run Pointer Location. When I try to install
Development.apk it says "Dev Tools could not be installed on this
phone.".

That event stream doesn't look good (though it doesn't look like you
included the whole thing so it is hard to tell). You can interpret it with
these constants for the first and second number:

The file I pointed to is the definition for the data -- the first number is
the class of event (like key or abs), the second number is the code (like
'a' or key or x for abs), and the third is the value. You should be seeing
this data fairly directly reflected in pointer location, except with the
Thanks for your help.
I've managed to fix the issue by patching some of the Java code. The
driver was reporting the wrong event scan codes: ABS_Z instead of
ABS_Y and ABS_RX instead of ABS_X (have no idea why). When that was
fixed it was just a matter of calibrating the screen. Here are the

Um, okay, but it seems like it would be best to fix the driver rather than
hack the platform to do the wrong thing. :}

Yes.

Note:
ok thats g8. But should i need to do any modification regarding that
because the kernel contains the driver for touchscreen. I found
somewhere that we need to use "TLIB", is it true? can't android
directly use the Touchscreen without any modification at user level?

If you publish a proper kernel drive you won't need to modify user space.
Note that currently we don't support calibrating as is needed for
non-capacitive screens, so you would need to find some other way to
calibrate such a screen's points.

Is this the case for every devices that if there is a kernel driver
for each device and that driver is published properly, then we don't
need to do any modification in the userspace, correct? for e.g i have
drivers for telephony(RIL), touchscreen, display, keyboard etc, in
this case i don't need t
Not necessarily, other things may need user space code. For example,
hardware accelerated OpenGL is provided as a user-space library that takes
care of talking with its driver in an appropriate way.
