Hello @Ruppie
Can you share a screenshot of the interface?
That should be doable on LVGL with some C logic.
- The 2-axis joystick could be an object (knob) within a container, make it draggable and track the x and y position, it could also re-center on release if needed.
- LVGL multitouch support was already added. I have not tested it, but your touch controller would also need to support it
