ESP 5" display with LVGL image flickering

baronbaron
in Elecrow HMI Display

ESP32 5" is connected via ESPNOW to an ESP32 without display.
When ESP32 5" receives data via ESPNOW a LVGL button changes the image using the Image property from default to checked. The image changes correctly but the whole page flashes.
Do you have any suggestions for me?

    Hello @baron,
    Could you please confirm if the ESP 5" display screen can display content normally when used independently and in refresh mode?

    I found old forum posts that suggest reducing the value of the variable cfg.freq_write = 10000000
    This setting solved my problem.

    Thanks for your interest
