Assumes:
- you are familiar with ESP32-2432S028R AKA Cheap Yellow Display (CYD)
- [ Ссылка ]
- you've already setup all the required libraries for ESP32-2432S028R and LVGL
- [ Ссылка ]
- Great setup instructions
- [ Ссылка ]
- This has lots of examples for LVGL
- you've done basic tutorials for LVGL with CYD
I use EEZ Studio because they support LVGL 9 and don't require login like Squareline.
I am learning about LVGL and ESP32 and documenting what I learn so it may help others.
Note: these tutorials can be done on any displays supporting LVGL.
