Supported color depths

The reference port for this board supports 16bpp color depth.

Enabling DeviceLink

The reference port package comes with a Qt Quick Ultralite DeviceLink library, which is not enabled by default. Enable it by editing the platform_config.h file as follows:

1. Open <QT_INSTALL>/QtMCUs/3.0.0/platform/boards/espressif/esp32s3-box3-idf/platform_config.h in a text editor.
2. Uncomment the //#define QUL_PLATFORM_DEVICELINK_ENABLED line so that the config looks as follows:

   #ifndef QUL_PLATFORM_DEVICELINK_ENABLED
   // Enable the device link component.
   // For more details, see Qt for MCUs CMake manual QUL_PLATFORM_DEVICELINK_ENABLED page.
   #define QUL_PLATFORM_DEVICELINK_ENABLED
   #endif

After the change, the exported projects have DeviceLink enabled.
