Other Parts Discussed in Thread: ADS7846, WL1271, TVP5146M2

Hi All,

I m using HT70JF i2c based Touchscreen with 7" inch LCD Display , But its not communicating with LCD ,

Where we need to change the board file ?

How to link the LCD with Touch Screen .when i touch the touch screen its shown the following interrupt .Can you Please give the Solution for this .

Hi Bhagavath,

First you need to check whether you receive interrupts from touch screen. You can use "cat /proc/interrupts" command for this.

Next You need to check whether touch events are reported by the kernel input subsystem. You can use "getevent" utility at android terminal.

If you get events for all touch instances with a nonzero, you can assure that the events will reach Android Event hub and the Input Manager.

Finally just need to calibrate the x,y values. You can follow the ads7646.c example done for the OMAP3EVM.

Hi Arun

Can you Please check get event ,interrupt & log file as below ..

-------getevent-------

add device 1: /dev/input/event2

add device 2: /dev/input/event1

could not get driver version for /dev/input/mice, Not a typewriter

add device 3: /dev/input/event0

add device 4: /dev/input/event3

Hi Bhagavath,

It seems you get interrupts from Touch Screen as indicated by this line in cat /proc/interrupts

203: 285 GPIO ssd2531

But when you do getevent, you should be able to get some events from /dev/input/event1

Check the driver code, whether it is receiving touch screen data and passing to the input subsystem by input-> report

Hi Arun,

we have done following changes in driver code as below, Touch screen is i2c based ,While touch the Screen ,its not getting x,y events.

static struct i2c_board_info __initdata omap3evm_i2c_boardinfo1[] = {
        {
                I2C_BOARD_INFO("ssd2531", 0x5c),
        },

omap_register_i2c_bus(3, 400,omap3evm_i2c_boardinfo1,ARRAY_SIZE(omap3evm_i2c_boardinfo1));

can you please tell the issue.

Thanks & Regards

Hi Bhagavath,

Some parameter passed to input_handle_event from ssd2531_do_work is incorrect. The parameter is expected to be a valid address but it is not.

You need to review the code in ssd2531_do_work to find out the wrong parameter and fix it. Once that is fixed, I believe you will get events when you run getevent.

Hello Arun,

We have enabled MULTI TOUCH option in the driver and now , we are able to see the interrupts while touching .

But we are not able to interact with either of the application appearing on the screen . We are able to see event getting formed regarding the touch panel (/dev/input/event1).

Certain clarifications we require , please help us on this

1. The driver file we have is for Linux OS , and touch screen is working with TI's latest linux SDK.

Will this driver will work for Android also ?

2. Do we need to modify the driver for ANDROID ?

If yes what changes we need to configure ?

3. Any Changes are required in Android filesystem to enable our touch screen ?

Thanks

Hi Bhagavath,

Android Event Hub detects all input devices registered under /dev/input/*

If the driver works fine on Linux SDK, then "getevent" utility in Android FS should also give the events.

Can you confirm your "getevent" android FS is working ?

Regarding

1. The driver file we have is for Linux OS , and touch screen is working with TI's latest linux SDK.

Will this driver will work for Android also ? YES

2. Do we need to modify the driver for ANDROID ?

If yes what changes we need to configure ? NO

3. Any Changes are required in Android filesystem to enable our touch screen ? Only calibration for resistive touch screens
