|
|
|
|
|
|
|
|
Import with `#include <lvgl/lvgl.h>` or `#include <lvgl.h>`.
|
|
|
|
|
|
|
|
|
|
Upstream example ported to NuttX is present at `examples/lvgldemo`.
|
|
|
|
|
|
|
|
|
|
LVGL can be used with framebuffer device. To find example boards with this
|

|
|
|
preconfigured, search for `CONFIG_GRAPHICS_LVGL=y` in `defconfig` files. All of
|
|
|
|
|
them have also `CONFIG_VIDEO_FB=y` present.

|
|
|
As a second option, LVGL can talk to a display driver and explicitly draw line
|
|
|
|
|
by line. For this case, there is no preconfigured board present. Go to _Porting_
|
|
|
|
|
section of upstream documentation for more hints.
