问题描述
我刚刚购买了带有7英寸显示屏触摸屏和外壳的Raspberry Pi 3.
I've just bought a Raspberry Pi 3 with a 7" Display touch screen and a casing.
不幸的是，机壳无法让我手动旋转屏幕，因此我的应用程序倒挂运行.
Unfortunately, the casing can't allow me to rotate manually the screen so my apps are running upside down.
我尝试使用以下adb命令从控制台执行此操作，但是没有运气:
I've tried to do it from the console using the following adb commands but with no luck:
adb shell content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:0
然后
adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:1
或
adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:3
是否可以通过配置标志直接从启动处理屏幕方向来进行此操作?
Is there any way to do it from a config flag directly that screen orientation is handled from boot ?
推荐答案
我终于找到了实现方法.
I find out finally how to achieve it.
找到的解决方案:带有Rasp3 7英寸触摸屏的Android Things
您必须从笔记本电脑上的sdcard挂载启动分区，然后编辑/boot/config.txt文件并添加以下行:
You have to mount the boot partition from the sdcard on your laptop and edit the /boot/config.txt file and add the following line:
lcd_rotate=2
通过添加此行，将旋转显示和触摸屏，而display_rotate=2仅旋转显示并且触摸屏保持上下颠倒.
By adding this line both display and touchscreen will be rotated, compared to display_rotate=2 where only display is rotated and touchscreen remains upside down.
