Hi Zare,

What touch screen device are you using and what interface has been used by TS ie ex SPI or I2C etc., ?

You need to add that touch screen device support in dts or board file.

You can take some reference code from other dts file or board file.

Hi Zare,

Have you checked the SDK for LDC3001 driver support ?

If not there then port the below driver in your SDK and pass your platform data from board file or dts to driver.

I already get the driver, but I don't have the lg101 program manual(It's required nda). who can tell me the i2c address ?
