LuatOS/module/Air8101/demo/rtc

功能模块介绍：

1、main.lua：主程序入口；

2、rtc_app.lua：无网络时初始化并每秒打印东八区本地时间与 UTC 时间；有网络时等待 NTP 授时后，同样每秒打印更新后的东八区本地时间与 UTC 时间；

演示功能概述：

1、第一种场景演示：无网络情况下，rtc时钟初始化并每秒打印东八区本地时间与 UTC 时间。

2、第二种场景演示：连接上wifi网络，等待 NTP 授时后每秒打印更新后的东八区本地时间与 UTC 时间。

1、Air8101核心板一块：

2、TYPE-C USB数据线一根 ，Air8101核心板和数据线的硬件接线方式为：

• Air8101核心板通过TYPE-C USB口供电；（5V / 3.3V 供电 拨动开关 拨到 3.3V供电一端，功耗测试开关 拨到 OFF）

• TYPE-C USB数据线直接插到开发板的TYPE-C USB座子，另外一端连接电脑USB口；

演示软件环境

1、 Luatools下载调试工具

2、 固件版本：LuatOS-SoC_V1006__Air8101，固件地址，如有最新固件请用最新 8101固件下载

演示核心步骤

1、搭建好硬件环境

2、demo脚本代码rtc_app.lua中，按照自己的需求启用对应的task函数

4、Luatools烧录内核固件和修改后的demo脚本代码

5、烧录成功后，代码会自动运行，查看打印日志，如果正常运行，会打印ntp时间同步成功、本地时间以及RTC时间等信息，如下log显示：

选择运行rtc_task2()函数，打印日志如下：
