unsure how to migrate LV_EVENT_DRAW_PART_BEGIN/END and unsure what else is lurking out there and what other re-engineering I need to do, so I'm about done with LVGL completely, because even if I somehow make it through this migration, I know it will happen again and again of v10,...
LV_EVENT_DRAW_PART_BEGIN Start the drawing of a part. This is a good place to modify the draw descriptors (e.g. rect_dsc), or add masks. LV_EVENT_DRAW_PART_END Finish the drawing of a part. This is a good place to draw extra content on the part, or remove the masks added ...
lv_conf.h是LVGL库的配置文件,里面有各种宏。 5.6 添加源码到工程组文件夹 接下来我们在 mdk 里面新建GUI/lvgl和GUI/lvgl_port两个组文件夹,其中GUI/lvgl用于存放 src 文件夹的内容,GUI/lvgl_port用于存放 examples\porting 文件夹的内容。 在GUI/lvgl组中添加以下文件夹中所有的.c文件: ...
