Simple application for getting Touch coordinates

prashantwagre — Wed, 05 Dec 2018 09:26:11 GMT

Hello,

I have Goodix G9271 Touch screen, my display is interfaced over LVDS.

The touch screen is working, we are able to get coordinates through TS lib package.

cat dev/input/event0 | hexdump is also responding and getting data in HEX.

I would like to create a small application, where an i can get the Touch screen coordinates directly for demo purpose.

Hi Prashant,

You can take the data directly from cat dev/input/event0 in your application. NXP does not have a file that show you the touchscreen coordinates.

Dear Alfred Soto,

I want to know how to handle the Touch in i.MX6Q / Linux 4.1.15.

I could find the Touch LVDS Interface is I2C, but I didn't find the source code for the LVDS Touch.

Please let me know how to control the LVDS Touch.

Best Regards,

Eric.
