Do the macro definitions in the lv.conf.h file have any impact on the demo example?

What do you want to achieve?

I would like to make some modifications to this example. On the Code::Blocks simulator, I can achieve the normal effect. However, when I port it to the microcontroller, only one color will appear.
Because I made some modifications (in lv_conf.h) during the transplantation process, so where in the modified files can this effect be restored?

Environment

  • LVGL version: 9.4`

There were problems in version 9.4. But after I switched to version 9.2, the issue was resolved.
