| <p>Upstream example ported to NuttX is present at <code class="docutils literal notranslate"><span class="pre">examples/lvgldemo</span></code>.</p> |
| <p>LVGL can be used with framebuffer device. To find example boards with this |
| preconfigured, search for <code class="docutils literal notranslate"><span class="pre">CONFIG_GRAPHICS_LVGL=y</span></code> in <code class="docutils literal notranslate"><span class="pre">defconfig</span></code> files. All of |
| them have also <code class="docutils literal notranslate"><span class="pre">CONFIG_VIDEO_FB=y</span></code> present.</p> |
| <p>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.</p> |
