LVGL 9.2 + esp32-s3 + display axs15321b

Hi,
I’m trying to port LVGL on a board with esp32-s3 and axs15321b display (QSPI)/touch driver(I2C).
I’m using LVGL 9.2.2 and esp_lvgl_port esp-idf 5.3.1 in ESP-IDE.

At the moment I have a firmware with LVGL that seems working, display shows and touch senses.
But I have problem during event widget refresh.
For example I have a code where I simply show a button with a callback on click event.
On first button display out, before any user interaction, the display shows the widget.
On click the rendering fails.

Here you have a screenshot before and after the “button100” press.

It seems something related to task concurrency in esp_lvgl_port library ?
Have you any suggestion where I could look at or something else to try?

Thanks to all of you.

Hi,
okay, after a lot of tries (… and sleepless nights :-)), I found that something goes wrong with partial buffer display rendering because via fulll refresh, the display seems working great… :slight_smile:
Now, I’m digging deeper about partial buffer corrupt displaying…
Byte… sorry, bye!

Would you mind sharing your code for this?
I’m having a hard time getting my display (JC3248W535) going with esp-idf and esp_lvgl_port and I’m banging my head against a wall right now it seems. lol
Thanks :slight_smile:
