I have work on this, today. Very long time to make it work like last time. Some weeks between today and the last time i worked on it. I didn't commit when it seems to work and somehow it doesn't today but not sure what i've changed in between.
Anyway the screen work but too long to update ~12s to change pixels state
I'm happy because it update througt time with lgvl library handling widgets.
I need some more understanding on some part but that's for another day.
