How to upgrade LVGL latest version


Hi All,
I want to upgrade LVGL version to latest 7.11.0
I already developed few screens in v7.0.0(current version)
So how to upgrade to latest lvgl version without disturbing the screens code.
What files should i pull from GitHub ?

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


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:

/*You code here*/

Screenshot and/or video

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

You should be able to simply replace your lvgl directory with the new one. 7.11 should be backwards compatible.

i upgraded lvgl version to 7.11.0 dev
after upgrade the screen get freeze(unable to click and when i try spinner widget loading got freeze)
i think i am missing something in lv_conf.h file
when i try with old lv_conf.h file it is working fine

please help me where i missed.

Thanks in advance

There’s not enough information to say what could have gone wrong. Have you enabled logging? Did any errors get printed? Have you tried using a debugger to see where it freezes?

Enabled log module in lv_conf.h file but nothing is printed

Have you registered a log callback or used printf?

issue resolved in my lv_conf.h LV_TICK_CUSTOM is not enabled. after enabling LV_TICK_CUSTOM all are working fine.

Thanks for your support.
