CONFIG_LVGL_IMG_CACHE_DEF_SIZE

Default image cache size

Type: int

Help

Default image cache size, image caching keeps the images open.
If only the built-in image formats are used there is no real
advantage of caching. With complex image decoders (e.g. PNG or JPG)
caching can save the continuous decoding of images. However the
opened images might consume additional RAM.
