LVGL没有现成的函数,我们可以用lv_timer_pause()和lv_timer_resume()函数组合实现. 注意,如果使用lv_timer_set_repeat_count=1指定循环1次数,中途打断用lv_timer_reset的话,因为定时器执行结束后会自动删除定时器,lv_timer_reset 无效.此方案不可取. 如果你有更好的方法,请留言. static char sound_src[256]=...

在你的情况下,如果使用了LVGL的Timer或Task来处理界面刷新,你需要在删除界面时停止这些Timer或Task。例如,如果你使用了之前提到的lv_timer_create和lv_timer_pause函数,你需要在删除页面时调用lv_timer_del来删除Timer。 c // 停止并删除Timer lv_timer_pause(global_param.lvgl_timer_refresh[0]); lv_timer_del...
