Touch Controller IC Part Number for iMXEBOOKDC5

Dear Team,

I am using the iMXEBOOKDC5 together with the i.MX8ULP EVK.

So far, everything is working well. The E-Ink display is functioning correctly, and both the buttons and joystick are operating as expected.

I would now like to enable the touch panel on the display. However, I cannot identify the part number of the touch controller IC used on the EPD module because the marking on the IC appears to have been erased by laser marking.

I have tried to find the information myself, but without success.

Could you please share:

1. The touch controller IC part number used on the iMXEBOOKDC5 display.
2. Any available Linux driver, library, or software package for supporting the touch functionality.

Thank you for your help.

Best regards,

Evaluation BoardRe: Touch Controller IC Part Number for iMXEBOOKDC5

Hello,

The touch controller IC used is the GT911, manufactured by Goodix Technology.

You can take a look into the driver in the next link:

Best regards.
