The display shakes when write on FAT


Hi everyone,
I have a problem that I can’t solve in any way…
When I write on FAT the display shakes during this process for a few moments, the only way to ensure that the user doesn’t notice this is to turn off the display while I write the file to FAT.
Do you know a way to eliminate this problem or alternatively suspend the display update while the file is being written?

What MCU/Processor/Board and compiler are you using?

ESP32S3 - Display 4827S043

What LVGL version are you using?


What do you want to achieve?

What have you tried so far?

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

File uploadFile =, FILE_WRITE);
uploadFile.write(buff, c);

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

Is it possible to suspend the display refresh?
