- 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.
Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.
