Place text on LONG_SCROLL_CIRCULAR Label

How-to
1

Hello!

I have a fixed width label. It is set to long_mode = LV_LABEL_LONG_SCROLL_CIRCULAR
I set the text that is longer than the label, so the text moves in a circle.

When I place a new text, and the existing one scrolls, I want to place the new text at the beginning of the label, so far this has not been the case.
How to do it?

Of course, I should have the possibility, that when I place some text, when I update only some number within the text (for example, seconds), that the text continues to move (not to be set to the initial position)
How to do it?

Hi,

I’ve just fixed it here: fix(label): fix updating scrolling label text by kisvegabor · Pull Request #7533 · lvgl/lvgl · GitHub

Can you update to v9?

Dear sir, thank you for your reply.

Unfortunately, I can’t upgrade to v9 right now because I’m 99.9% done with devices that have screens made with LVGL v8. I’m in the final stages of testing and fixing issues I’ve noticed LVGL has. I’ve run into a few, this is one of them. There are more that I haven’t asked for a bug fix for anywhere.

My goal is to fix the necessary functions within LVGL v8, which will solve the observed problem.

Tnx
