5. Call lv_timer_handler() every few milliseconds to handle LVGL related tasks. 首先,调用lv_init方法,初始化LVGL。 然后,初始化我们的驱动。再把显示和输入设备驱动注册到LVGL。 再然后,周期性调用lv_tick_inc,用以报告已经过去的时间(其实就是给LVGL提供一个时间基准)。 最后,周期性调用lv_timer_handler...
步骤三:更新超级循环 最新版本的LVGL为用户提供了一个全新的方式来周期性的刷新 LVGL任务函数:lv_timer_handler_run_in_period(毫秒数)。无论是裸机还是RTOS环境,你都可以简单的将其插入超级循环中——以指定的ms数为间隔刷新LVGL的任务函数,例如: 登录后复制intmain(void){...lv_init();lv_port_disp_init()...
主程序中每隔数毫秒(5ms)调用lv_timer_handler()处理LVGL界面(绘制显示界面,读取输入设备信息,展示动画等)。 初始化显示驱动 初始化lv_disp_draw_buf_t && lv_disp_drv_t这两个结构体然后对应初始化绘制缓冲区的内部图形缓冲区,显示驱动程序。 初始化缓存区 ...
