- Remove the EXAMPLE_LCD_IMAGE_SOURCE Kconfig option (embedded binary vs
file system) and always load images from LittleFS.
- Convert the PNG images into LZ4-compressed LVGL binary images (.bin)
at
build time using LVGLImage.py, and flash them to a LittleFS partition.
- Upgrade lvgl to 9.6.0 and add the espressif/lz4 component; link the
external LZ4 library into lvgl.
- Split the example: main.c focuses on the esp_lcd i80 API, while the
LVGL
porting (lvgl_port.c) and the UI (lvgl_demo_ui.c) live in separate
files.
- Rework the demo animation to use the LVGL animation engine (lv_anim)
with
easing paths instead of a manual software timer for smoother
rendering.
- Remove the embedded C image arrays (esp_logo.c, esp_text.c) and the
obsolete sdkconfig.ci.image_in_{bin,fs} variants.
