LVGL v8 status ? Animation with Square Line Studio

We use GitHub issues for development related discussions. Please use the forum to ask questions.

Describe the issue Hi All,

I'm starting a nexw project based on Lilygo T display ESP32S3 and LVGL.

I'm able to create a screen with the nice and usefull tool SquareLine Studio. I can display it on the devkit.

I tried to add an animation on my image. I export the ui from sqaure line studio and tried to build on vscode. But call to function "" refer to undifined function.

After comparing v8 to v7 , i saw tat this function were not present in v7. So i need to go on v8 to benefit of it.

I tried to create a blank project, and add lvgl as a submodule to have v8 ready to use. But it seems that KConfig of lv_port_esp32 and last v8 lvgl are different. I don't find all the same options in menuconfig.

So should I only modify the Kconfig and add the missing options present in the lv_port_esp32 version may be? Or is there also other changes to do and it is more complex than that?

I saw the first ticket on this topics that exist for one year now but still open.

Thank you !

+1 for official LVGL v8.x support

[hayschan]

hope v8 support +1

[MrMarteng]

+1 from me as well. Still trying to get LVGL running with lvgl and regular drivers library

I also got some customer request for ESP32-LVGLv8 support and I really like to have this and lvgl_esp32_drivers repos updated.

As v7 and v8 differ only in some minor API changes in the drivers I think it's not that difficult to update them.

Unfortunately, I don't have enough hardware for a deep enough testing, however you might have already seen our sponsorship program. From our donations I'd be happy to give 300 USD for updating these repos to v8. Does it sound like a fair offer?

Would you be interested it?

With some help from @sukesh-ak I have changed to use LGFX Master with LVGL v8. Have a look at https://github.com/sukesh-ak/ESP32-TUX

So far that has worked very well with ESP-IDF v5.x but I have only tried it with ESP-WROVER-Kit v4.1 and the Makerfabs 16bit parallel+touch devkits.

The only changes I have had to make to get a clean compile are: lv_demo_stress.c: lIne 77 change first %d to %lu lv_example_table_2.c: line 95 change first %"LV_PRIu32" to %d

So the burning need from our side is gone and the $300 can be saved by using LGFX
