Usage
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
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.
