- 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.
- Replace SPIFFS with LittleFS as the preferred
NOR flash file system
- Expand the Image Resource section in README with
detailed file system documentation
- Add pytest_i80_controller_lvgl.py to test both
image_in_bin and image_in_fs configurations
- Increase LVGL task stack size from 4KB to 8KB to
prevent stack overflow when loading images from FS
- Add CONFIG_LV_USE_CLIB_MALLOC to sdkconfig.defaults
Made-with: Cursor
Currently, several examples do not explicitly state their component
dependencies, relying instead on the default behavior that includes all
registered components and commonly required ones in the build.
Explicitly adding component dependencies can reduce build time when
set(COMPONENTS main) is used.
