WICED 开发 Redbear Duo

使用 WICED SDK 开发 Redbear Duo

花了三天时间琢磨这个WICED，终于理清了头绪，网上资料太少，还得要从 SDK 文档入手。原来2016年4月博通将 IOT 业务卖给了 Cypress (赛普拉斯)，这个WICED以前是博通的，感觉用的人还是很少，而且用的 RTOS 居然是 ThreadX ，好像很小众的样子，不过居然美国宇航局的太空撞击器就是跑到这个系统，好吧你牛X！

编译程序

参考 RedBear 官方文档FW_Make ，示例如下：

./make redbear.rgb-RB_DUO

下载编译的固件(firmware)

由上图得到到Duo 下载使用如下指令：

dfu-util -d 2b04:d058 -a 0 -s 0x80C0000 -D rgb-RB_DUO.bin

在 WICED_SDK/apps 中有很多实例，具体可以查看里面的 Readme.txt 文档，里面有说 apps/snip 文件夹中多是各种 WICED API 实例。首先从 scan 开始入手，用于扫描可用的路由，代码如下：

make snip.scan-RB_DUO

可能这个 make 工具是定制的？？？ 编译的信息很详细了，总之，很高大上。显示如下：
