Touchscreen support for 7 Inch LCD panel

[Gokul Nagarajan]

Hello all,
We are working in OMAP3530 processor. We have changed the LCD size
from 480 x 272 to 800 x 480 .
We have changed the front panel parameters accordingly and we are able
to get Android screen properly.

Currently we are working in touchscreen . We are using ads7846 touch
screen controller.

We have tested Touch screen through tslib calibration after linux
booting. Its able to sense it.

But in Android it should not able to sense the proper positions.

we would like to know , how the xmin, xmax, ymin and ymax parameter
values are calculated for the new LCD resolution?

ie For 480 x 272 the following values are given in the board file

struct ads7846_platform_data ads7846_config = {
//#ifdef CONFIG_ADS_SCALED_EV
.x_min = 0,
.y_min = 0,
.x_max = 3800,
.y_max = 3800,
//#else
// .x_max = 0x0fff,
// .y_max = 0x0fff,
//#endif

.x_plate_ohms = 180,
.pressure_max = 255,
.debounce_max = 20,
.debounce_tol = 10,
.debounce_rep = 1,
.get_pendown_state = ads7846_get_pendown_state,
.keep_vref_on = 1,
.settle_delay_usecs = 150,
};

We would like to know for the new LCD 800 x 480 , how this value
should be calculated?

Gokul,

You need to take those TSLIB generated calibration information and
then feed that into Android so that it can properly scale the incoming
X, Y, and Z coordinates from the touch screen controller..

I've ported the TSLIB package into Android and added the hooks into
Android 1.6, you can check them out at:

TSLIB - http://gitorious.org/android-omap3logic/external-tslib
Android Changes - http://gitorious.org/android-omap3logic/frameworks-base

Hi Ashwin,

Thanks for your suggestion, Could you help me in adding these files
to Android source.

I have added the TSLIB to the external folder of Android Source and
Framework related files to the framework/base folder of Android
source.

Now do we need to have any changes in Makefile to include TSLIB
package to be build.Any suggestion regarding this.

Thanks
Mohamed Fasil

can u try this? without doing much, you can just go to the folder,
below command will straighaway will start building the module
$source <mydroid>/build/envsetup.sh
$mm

You can plugin a 'Android.mk' file to build system, by placing the
folder in <mydroid>/<some-dir>
then upper directory's Android.mk files shall include subdirecties'
make files, by either a call like 'include $(call
all-subdir-makefiles)' or directly by handpicking 'include
<path-to-.mk-file>'
so, now if you run 'make' at top level, you will see if its included
or not. (introduce some junk to make build fail, so u know for sure
its included)

Hi Deva,

After adding the corresponding files to the Android source and
on building the source, I m getting the following errors due to the UI
part of TSLIB, Any suggestion for this, I m using Android donut-1.6

Hi,

A version mismatch between below header versions might cause such
build errors. i checked and they match your build errors.,

TSLIB header:
http://gitorious.org/android-omap3logic/frameworks-base/blobs/ee594708228548bebd3266c87f51fa4810499f45/base/include/ui/EventHub.h

Donut header:
http://git.omapzoom.org/?p=platform/frameworks/base.git;a=blob_plain;f=include/ui/EventHub.h;hb=donut

I guess you got EventHub.h from TSLIB git, but EventHub.cpp is from
donut release.

If you are using TSLIB version, you should have picked EventHub.cpp from
http://gitorious.org/android-omap3logic/frameworks-base/blobs/ee594708228548bebd3266c87f51fa4810499f45/base/libs/ui/EventHub.cpp
then you wouldnt have faced this break..

then you can see the function signature matching there
bool EventHub::getEvent(InEvent *inevt)

[Ashwin Bihari]

Deva has it correct..if you're going to use anything from the
android-omap3logic repository, please use all of it. The files in
there are provided as a whole package..

-- Ashwin

[Fasil]

Hi Ashwin, Deva,

I already have a working source of Donut Android taken from
Android git(repo). For calibrating the touch screen in 7" inch LCD we
need the TSLIB utility in Android. Thanks for suggesting the
Omap3Logic git.

Once I got the TSLIB git, I added to external/tslib
frameworks/base/
include/ui
frameworks/base/
libs/ui
frameworks/base/
services/jni

After adding the above files once I build the source, I got the
EventHub.cpp file error, But after changing the EventHub.cpp from
Omap3logic, there is no error from this file.

Now I m getting a error in frameworks/base/include/ui/ITSLib.h saying
one of the file tslib.h is not available. Is this the same file where
we find in external/tslib/src/tslib.h or someother file..

target thumb C++: libui <= frameworks/base/libs/ui/EventHub.cpp

In file included from frameworks/base/libs/ui/EventHub.cpp:19:
frameworks/base/include/ui/ITSLib.h:8:19: error: tslib.h: No such file

HI,
tslib is in actual TSLIB library source path..

link:
http://gitorious.org/android-omap3logic/external-tslib/trees/9ba15a6640dfe67a4f70d204c39fe9ac678c59bb/src

As per Ashwin's mail, you should do below steps in your <android>/ folder..
Copy complete http://gitorious.org/android-omap3logic/frameworks-base
source tree to ./frameworks/base
Copy complete http://gitorious.org/android-omap3logic/external-tslib
source tree to ./external/tslib

[Fasil]

Hi Deva,Ashwin,

Thanks for your valuable inputs, I got the successful
build. But When I tried in the target I got the following error. Any
suggestion for the cause ...

# ./system/bin/ts_calibrate
open fbdevice: No such file or directory
#

Thanks
Fasil

[Ashwin Bihari]

Fasil,

You'll need to do the following:
export TSLIB_CONSOLEDEVICE none
export TSLIB_FBDEVICE /dev/graphics/fb0
export TSLIB_TSDEVICE /dev/input/event2
export TSLIB_CALIBFILE /etc/pointercal
export TSLIB_CONFFILE /etc/ts.conf
export TSLIB_PLUGINDIR /system/lib/ts

You may have to set the TSLIB_TSDEVICE to be the right one on your
target. Realize that trying to run ts_calibrate while Android is
already up and running means that you'll have TSLIB and Android
fighting to shove their data to the framebuffer and through it to the
screen.

I'm going to be adding a new calibration application to my
android-omap3logic project to hopefully help with this..

Regards
-- Ashwin

[Fasil]

Hi Ashwin

We are able to calibrate the Touchscreen in Android.We are able to
run the ts_test application.It works fine.

After reboot, Android doesnt able to sense it.
Is it manually we have to pass those calibrated data to Android ?

Thanks
Fasil

Hi,

You need to run ./ts_calibrate to store the calibrated data to
/etc/<calibration> file..

refer http://www.opentom.org/Tslib

[Gokul Nagarajan]

Hi Ashwin,

We are running ts_calibrate application once after Android boots up.

Once it is done,we are touching the menu's in the Android Screen, but
it doesnt sense it.
Please support us.

[Ashwin Bihari]

The ts_calibrate only needs to be run once and the output of that
should be saved in the file /system/etc/pointercal. This will be the
file that the TLSIB within Android will use to scale the inputs.

Run the "getevent" at the serial port and check what the touchscreen
input device is and you'll need to add the TSLIB_TSDEVICE environment
variable in your init.rc file to set it properly for TSLIB to use..

[Gokul Nagarajan]

Hi

We run the "getevent" from the terminal and from that we have set
TSLIB_TSDEVICE to /dev/input/event1.
Then we run the ts_calibrate application and the calibrate values were
found in /system/etc/pointercal.
But still if we press on the Menu's in the Android,it didnt able to
sense it

Hi,
This shouldnt be the case, and not sure where the break can be..,

can you add traces and check,
- at kernel touchscreen driver when it updates coordinates by
input_sync_abs calls?
- some logcat logs in Android touch screen (i/p) ui libararies?

Hi Deva,

we have tested the touchsreen driver already with 480 x 272 lcd in
Android. Now we have changed only the LCD size to 7 inch.ie 800 x
480.In driver side we have modified the x_max, y_max, x_min, y_min
parameters and the touch screen is working find in linux.We feel the
problem is around the xmin , ymin, xmax and ymax values for which
Android is not able to grab the correct values. Any suggestion or
workarounds for this issue. I m pasting the selected Logcat messages
below

Thanks and Regards

Hi Gokul,

You have to integrate the tslib to EventHub.
Here is the example:

hi,

I am porting 4.3 touchscreen (has tsc2046 controller) to beaglboard
with android

Kernel driver porting completed

I applied your external/tslib framework/base and initrc "export X""
patchs.

and run ts_calibrate. samples succesfully collected to /etc/
pointercal

but after reboot

after splash , the desktop has not appeared and I have taken the
following errors

binder: release proc 874, transaction 767, not freed
binder: 765:782 transaction failed 29189, size168-0

binder: 765:783 transaction failed 29189, size4-0
