    • Hi,

      You have to read out the touch data from the touch controller and pass the read touch coordinates to emWin. Typically we do this in a dedicated task polling the touch data every 25ms.

      The interface and communication to the touch controller is user defined and not part of emWin.

      Attached is a touch configuration we use on a STM32F746 Discovery. You might use it as a reference.

      Regards,
      Sven
