Hi3861 OpenHarmony嵌入式应用入门--hello world
这篇文章我们开始根据自己的开发板编写测试例程，通过编写例程来更好的学习。
目的：使用开发板上电后周期性打印“hello world”
我们需要创建自己的开发板工程目录，这里大部分时候会参考hqyj开发板的目录，但是我们会从0开始，这样能够更好的了解我们的工程中有哪些是我们自己的，哪些是鸿蒙sdk的。

在D:\DevEcoProjects\test\src\vendor创建文件夹rtplay，里面创建rt_hi3861，编写config文件，复制D:\DevEcoProjects\test\src\vendor\hqyj\fs_hi3861\config.json文件为 D:\DevEcoProjects\test\src\vendor\rtplay\rt_hi3861\config.json，并修改里面的开发板信息。
