Silicon Labs EFR32 RF射频测试-RAILTEST
Silicon 提供了很多例程，这里介绍怎样生成和配置RAILTEST工程，我使用的官方开发板，所以有现成的例程，不需要做更改，但是我们的产品往往都是需要作一些修改的，以下内容将讲述如何配置一个RAILTEST工程：
1、新建一个RAILTEST工程流程如下：
下面的比较重要，选择开发板型号（没有开发板的可以不选）和芯片型号（必须选择），然后点击 “Finish”按钮生成工程。
2、生工程后IDE会自动打开配置文件，选中Plugins项，配置输出输入设备，如果你没有使用Silicon提供的显示屏，那么需要将Application Graphics插件前面的“√”去掉，我有显示屏，所以√上，如图：
3、如果的串口位置和默认的不一样则需要更改位置，这里的SERIAL使用USART3，注意需要把USART3的“Enabled”也打√，如图：
4、配置完后保存文件，然后点击右上角的“Generate”生成代码；
5、生成的文件如下图，如果在步骤2中没有选择“Application Graphics”插件的话可以将图中框起来的几个文件删除；6、编译后将代码下载到IC，连接串口到PC，使用串口助手查看log，如下：
7、如果有显示屏的话你可以看到下图所示的界面：
8、没有按键的话可以直接使用CLI操作，RAILTEST工程提供以下接口，在app_ci.h文件可以找到：
