Also added the Zephyr logo.

manifest_all_v1.1.0.json is not edited directly. A GitHub Action runs every 12 hours to update it automatically. https://github.com/lvgl/lvgl_project_creator/actions

@liamHowatt thanks for that, I was wondering if the manifests should be generated using the python script or if the actions would be responsible for that.

Now it is clear :)

Removed the conflicts and added esp32 based board PTAL again

Looks good in general! I love the simplicity of the Zephyr project.

@richardgazdik please take a look at the logo.

Why do you call lv_timer_handler() here. If it's a workaround please add a comment.

Here it has full Markdown support, so you can use a link too. Now there is an issue with the links though: they open in the window of the project creator an not in a browser. @richardgazdik will fix it this week.

I think this extra call from the lv_timer_handler sounds like a leftover, since I grabbed the initial code from the modules/lvgl zephyr samples and simplified it.
