Happy new year everyone! I had some time to revisit this and changed the xpt7603_read callback to always return false
Good news: it resolved the blocking issue I was seeing before. I can touch the screen and animations will still do their thing:
Bad news: touch input still isn’t properly propagating to the rest of lvgl.
My test script has a button with a callback attached and the callback never gets called no matter what I do.
Appreciative of any ideas and pointers
