移植之前 首先来建立一个工程，用Keil5自带的Pack建库是再合适不过了![未命名1534475667.png](/uploads/201808/17/111513u7k3snlc1asvdzxz.png)

建立好工程后，下面就进入移植工作了。先将rtthread开发包解压，将以下文件夹拷贝到工程文件夹中：
![未命名1534476313.png](/uploads/201808/17/112525rnagacgvoyv3pfha.png)
接着进入rtthread\bsp文件夹，找到对应芯片文件夹，进入后拷贝rtconfig.h文件到工程文件夹中：

进入drivers文件夹，拷贝此次需要用到的文件：

进入工程并添加相应文件：
 t-thread\src文件夹下为内核文件，必须添加
 t-thread\include头文件文件夹需要包含到工程中
 t-thread\components\finsh文件夹下的文件添加到工程目录
 t-thread\components\drivers\serial为串口中间层，需要添加
 t-thread\libcpu\arm\cortex-m3中的*cpuport.c*和*context_rvds.S*两文件，并将 t-thread\libcpu\arm\common内容一并添加

完成后，将拷贝到的两个文件board.c与usart.c添加进工程，然后在board.c中主要实现以下两个函数：
```<blockquote>#if defined(RT_USING_USER_MAIN) && defined(RT_USING_HEAP)```修改rtconfig.h文件，用以完成对rtthread的配置

```连接好串口，或者软件仿真发现可以使用msh命令查看系统工作状态了
