在每次调用flush_cb时,我们更新last_flush_time的值为当前时间。同时,在需要判断最后一次刷新时间的地方,我们可以通过读取last_flush_time的值来获取最后一次刷新的时间。 下面是一个示例代码: #include"lvgl.h"#include// 全局变量,用于记录最后一次调用flush_cb的时间time_tlast_flush_time=0;// 刷新回调函数voi...

calling lv_task_handler() againbeforelv_disp_flush_ready()is safe, and it would do nothing visible from the outside (e.g. no newflush_cb); calling lv_task_handler()afterlv_disp_flush_ready()would make it draw the next dirty block in case of partial screen update, if needed. ...
When I worked with an eInk display, I used the monitor_cb hook to trigger display updates, because my hardware had a framebuffer which could be written to at any time, and I could trigger the actual ink to update once all the individual flushes were done. Do you have that ability? Con...
