Here you’ll find a basic project for the Elecrow HMI Basic Displays (5" and 7" as examples). The smaller ones should work too with some pin adjustments.
This might help a bit to move away from LVGL 8 and use newer features.
Thanks for sharing this. This looks like a useful starting point for anyone moving from LVGL 8 to LVGL 9.5, especially with the Elecrow displays. I’ll definitely keep this project in mind for future work.
