In my first release I created a touchscreendriver that read the x-y coordinates from the pinetime screen.
Meanwhile a rudimentary touchscreen driver exist in Zephyr. (KSCAN_TOUCH)
It integrates with LVGL.
I managed to adapt the driver from Focaltech, so it now supports the Pinetime as well.
However it is not capable of detecting events like “slide up/down”, but point and click is usable.
