【CC3200 评测】CC3200-LAUNCHXL开发板使用心得分享 + 2、创建项目 点亮LED

Other Parts Discussed in Thread: CC3200

    从开发板的SDK中复制相关的文件到自己创建的项目文件中,方便学习和使用。从点亮一个LED灯开始。

 

    一、创建项目文件

   1.1、官网获取SDK:SDK

    

     

    1.2、将SDK文件中的下面文件复制到我创建的项目文件中

    

    

    

    1.3、下面是我创建的项目文件夹

    

    1.4、下面是创建的工程项目。

    

 编译工程没有错误。

    

    二、LED部分代码

    2.1、LED硬件电路

    

2.2、GPIO驱动LED部分的代码

    三、仿真程序

    

 

    五、执行结果

    D5,D6,D7 红、绿、蓝LED灯交替点亮,创建的项目完成,程序可以运行。
