    • linuxfb屏幕旋转90度

      前言

      事情是这样的，在开发板上使用Qt来做一些界面开发，但是我们是用的屏幕是800*1280的屏幕，也就是横向打点，就是说宽比长要大，做界面的话不太好看，所以在不改变驱动和设备树的情况下，在应用层实现屏幕旋转也能满足我们的需求。
      由于开发板上面没有显卡，像openGL、EGLFS这种来实现屏幕旋转也不现实，所以最终还是只能使用Linuxfb。但是Qt5的Linuxfb不支持旋转，所以需要拿到QT Linuxfb的源码自己添加一些参数就能实现了。
      网上找了一下，只找到了一个5.4的patch，直接用用不了，所以就要只能自己来改源码，
      这里用的是buildroot来构建Qt系统的，下面介绍如何获取并修改源码，如果不想修改的可以直接复制补丁文件，生成patch，打patch。

      一、源码获取

      在buildroot构建系统中，有一个dl目录，存放的都是各种源码，其中QT的源码就放在里面。
      在这里插入图片描述
      在这里插入图片描述
      我们将源码拷贝一份，创建git仓库，使用git进行打补丁。修改后，生成pach，将pach打入源码中即可。

      二、修改源码

      源码修改完成后，初始化git仓库，打补丁。

      git init
git add .
git commit -m "test"
git format-patch HEAD^

      三、将补丁拷贝到指定目录

      buildroot构建系统，它会自动将补丁打上，所以我们只需要将上面生成的补丁放到指定目录下即可。
      目录如下：

      neza-d1-buildroot/package/qt5/qt5base

      下图即是我们添加的补丁。
      在这里插入图片描述

      四、编译

      make

      编译完成即可完成屏幕旋转了

      五、添加环境变量

      由于屏幕旋转过去了，但是触摸屏还没旋转，所以我们需要添加QT环境变量配置触摸屏，这里用的是TSLIB进行触摸屏校准的。
      在/etc/profile文件最后添加下面内容，其中TSLIB_TSDEVICE后面的event根据自己屏幕event设备进行填写。

      export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event5
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_QPA_GENERIC_PLUGINS=tslib:$TSLIB_TSDEVICE

      重启系统即可。
