## 功能模块介绍

1、main.lua：主程序入口；

2、bit64_app.lua：32 位系统上对 64 位数据的基本算术运算和逻辑运算；

## 演示功能概述

1、创建一个task；

2、演示在 32 位系统上对 64 位数据的基本算术运算和逻辑运算；

## 演示硬件环境

![](https://docs.openluat.com/air8101/luatos/common/hwenv/image/Air8101.png)

1、Air8101核心板一块

2、TYPE-C USB数据线一根

3、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口连接TYPE-C USB 数据线，数据线的另外一端连接电脑的USB口；
- Air8101核心板通过TYPE-C USB口供电（核心板背面的功耗测试开关拨到OFF一端）；


## 演示软件环境

1、[Luatools下载调试工具](https://docs.openluat.com/air8101/luatos/common/download/)

2、[Air8101 最新版本的内核固件](https://docs.openluat.com/air8101/luatos/firmware/)


## 演示核心步骤

1、搭建好硬件环境

2、Luatools烧录内核固件和demo脚本代码

3、烧录成功后，自动开机运行

4、出现类似于下面的日志，就表示运行成功：
