第一步:首先调用lv_init初始化LVGL图形库。 第二步:lv_port_disp_init注册显示驱动程序和lv_port_indev_init输入设备驱动程序。 第三步:lv_tick_inc(x)在x中断中每毫秒调用一次。 第四步:lv_timer_handler每隔几毫秒周期调用一次,处理与LVGL相关的任务。 4. 显示设备 lv_disp_draw_buf_t /*绘制缓冲区*/...

使用LVGL 内部 Timer 来替代LVGL轮询线程,将刷新任务放到Timer回调函数中执行,我的程序中创建了两个页面,这里直接创建两个周期Timer,一个Timer用来刷新第一页的控件,另一个Timer用来刷新第二页的控件。 当进入首页时先启动第一个Timer,停止第二个Timer
