以绘制一条线为例,我们可以使用lv_draw_line函数。该函数的定义如下: void lv_draw_line(const lv_point_t* p1, const lv_point_t* p2, const lv_draw_line_dsc_t* draw_dsc); 其中,p1和p2分别是线的起点和终点,draw_dsc是一个绘制描述对象。 下面是一个绘制线条的示例代码: lv_draw_line_dsc_t ...
You also have the ability to draw masks but the most important part of it which is lv_draw_mask_rect_dsc_t is in the private scope. No documentation on how to use that at all. lv_draw_line_dsc_t, what is blend_mode?? the docstring for raw_end doesn't really make any sense. ...

lv_conf.h,配置文件。 移植过来后大概的目录结构 然后建了个 lvgl 文件夹一股脑塞进去。记得要配置 CMake(Keil 的话就是配置 IncludePaths,这里用 Keil 好像有点痛苦的),而且都要一个一个加进去,因为里面的 #include 路径都挺,呃,一堆上级目录符号,如果不想每个都改的话不如把所有目录都加进 CMake,这样就...
