(7)填充、修改lv_port_disp.c lv_port_disp.c里面的内容主要有: 我们需要重点关注lv_port_disp_init显示接口初始化函数与disp_flush屏幕刷新两个函数。 其中,lv_port_disp_init函数里主要要选择一种写缓存的方式及设置显示分辨。我们选择第一种写缓存的方式,修改后的函数如: // 微信公众号:嵌入式大杂烩voidl...

然后,我们在main函数中创建了两个屏幕对象screen1和screen2,并将它们分别关联到显示驱动器结构体disp1和disp2中。最后,通过lv_disp_trig_update函数触发刷新操作,从而在不同的显示设备上显示不同的屏幕。 综上所述,通过lv_disp_drv_register多个品目,我们可以在LVGL中注册多个显示驱动器,从而实现在多个屏幕或显示设...
