Hello,

The screen flickers with this demo file: Flickering screen runing Lesson 9 LVGL Servo Conctrol on CrowPanel 7.0".
It's very unpleasant for the eyes.

CrowPanel-ESP32-Display-Course-File-main\CrowPanel-ESP32-Display-Course-File-main\CrowPanel_ESP32_Tutorial\Code\Lesson 9 LVGL Servo Conctrol\4.3-5-7inch\CrowPanel_ESP32_LVGL_Demo

Could you tell me how to correct this?

Regards

    Hello @lboue ,
    Please try changing the frequency rate to 14000000

    @Elecrow
    I change the frequency rate to 14000000 line 69:
    cfg.freq_write = 16000000;
    to
    cfg.freq_write = 14000000;

    But I always notice a flicker that I don't get with the desk lamp example.

    Hello @lboue
    I'm sorry I don't quite get it, could you please take a video to help us better understand the problem?
