    • FAQ

    • In the event of data loss after removing the USB flash drive, what should be done?
      When removing the USB flash drive, please select "Eject" on the computer instead of physically unplugging it.
    • What should I do if I accidentally delete the content stored on the display screen's USB drive?
      You can re-download the corresponding content from the product's WIKI in the documentation download section.
    • When the display screen is accessing content stored on a USB drive, why does the screen turn white and not display the content when a USB interface is connected to a computer? It also doesn't display the content after disconnecting the USB interface.
      This is because the USB storage content is being occupied by the computer and cannot be accessed by the MCU of the display screen. The correct solution is to power cycle the display screen.
    • What should I do if the previous program's display content continues to appear during programming?
      This is because the MCU of the display screen does not execute the command to clear the previously called display effects, causing the content of the previous program to still be displayed. The solution is to call the "clear screen" command in the initialization code of the display screen before each program execution.
