【摘要】 本实验基于STML431_BearPi裸机工程,移植Huawei LiteOS操作系统。

上一期:基于小熊派开发板的物联网实战开发(二)-调测NB-IoT模组

请完成前两期的实验再来操作本期实验。

本实验基于STML431_BearPi裸机工程,移植Huawei LiteOS操作系统,在LiteOS操作系统基础上,移植智慧农业传感器代码,与NB-IoT模组通信,实现数据上报,并通过平台下发控制指令,开发板接收命令并对命令进行应答。

本期博客介绍移植Huawei LiteOS操作系统部分。

移植Huawei LiteOS操作系统、

打开LiteOS Studio,点击“工程配置”按钮;
