ESP32 S3 music demo performance on lvgl 8

General discussion

Hello everybody,

I am getting a 800x480 panel set up and running lvgl 8.3.11. The benchmark is currently doing 14 fps with direct mode on 2 full screen spiram buffers.

I believe that 2 small buffers dma’ed to spiram would be faster, but before trying I would like to ask if anybody else has benchmark numbers already.

Thank you.

Hi,
is it SPI or RGB565 based one?

Sorry for the lack of details.

It is a ESP32-S3 with 16bit RGB.

So there are dual full size buffers and lvgl is rendering directly to them, eventually swapping when drawing is complete.

The question then is: Is it better to draw to smaller sram buffers and DMA to the full buffer or leave as it is now?
