Hi,

Just to be sure I understand correctly: in a demo or example we should create a few mutexes and threads with printf-s to demonstrate that OS layer is working well.

If so, I think it should be rather an example which could be also a good starting point for anyone using LVGL with an OS. (E.g. show that lv_timer_handler needs to be protected by a mutex). I can imagine something like this:

1. We have the main thread in which a button is create
2. A new thread is created, which creates a label, and waits for a signal
3. When the button is pressed, a signal is triggered, and the other thread increments a counter and updates the label.

Besides the example - as you have mentioned - there should be a test too at least for pthread, but I think it's simpler as we can write any complicated code.

We need some feedback on this issue.

Now we mark this as "stale" because there was no activity here for 14 days.

Remove the "stale" label or comment else this will be closed in 7 days.

Sorry for not responding. GitHub doesn't send notification about reactions and I didn't notice the 👍

We will work on it!

Hey @kisvegabor 😃, no worries. Maybe I'll find some time to work on this :^)
