LicheePi Nano 运行lvgl只有半截，无全屏

lanjackg2003 · 2019-10-29 22:12:43

如视频所示,在我的平台上面运行lvgl只有半截
我的设备分辨率是800*480(从设备开机的log可以看到)

在linux下的dts配置如下

与LCD屏幕相关是参考荔枝派Nano官网设置的

		enable-gpios = <&pio 4 6 GPIO_ACTIVE_HIGH>;

			#size-cells = <0>;

			panel_input: endpoint@0 {
				reg = <0>;
				remote-endpoint = <&tcon0_out_lcd>;
			};
		};
	};

lvgl里面也配置成800*480(程序运行起来的时候也能够打印)

请问这个问题应该如何解

但是lvgl运行时候，任然检测到系统是800*480的分辨率，屏幕的Ui界面仍然是非全屏

firstman · 2019-10-30 08:35:20

屏幕的Ui界面仍然是非全屏是怎样的？你屏幕分辨率是多少？

xm1994 · 2019-10-30 14:46:59

设备分辨率都是手动指定的，不存在自动检测这一说。所以请查阅面板的spec并正确设置分辨率。

xm1994 · 2019-10-30 14:47:30

这是土鳖的arm嵌入式设备，不支持诸如EDID之类的显示器信息交互协议

我用的是荔枝派淘宝店铺标配的 5寸电容屏应该是800*480

我在Uboot里面设置了1024*600 或者800*480 都是可以开机

但是运行lvgl的时候，确实是lvgl的linux项目工程通过io读取的屏幕分辨率及位深

不知道你说指定设备分辨率是否指的是uboot设置屏幕分辨率？

xm1994 · 2019-10-30 21:59:48

确实是lvgl的linux项目工程通过io读取的屏幕分辨率及位深

lvgl是从framebuffer读取的分辨率，而framebuffer汇报的分辨率是从内核使用的dts中panel项设置的

好的谢谢

这个问题解决了，是我的一个失误导致的

#define LV_HOR_RES_MAX (800)
#define LV_VER_RES_MAX (480)
被我写成
#define LV_HOR_RES (800)
#define LV_VER_RES (480)

然后lv_conf_checker.h文件的代码中会有如下处理

#ifndef LV_HOR_RES_MAX
#define LV_HOR_RES_MAX          (480)
#endif
#ifndef LV_VER_RES_MAX
#define LV_VER_RES_MAX          (320)
#endif

因此，每次开机都是480*320的分辨率

请问移植lvgl必须将系统集成到TF卡么，可以移植到SPI Flash 么？
