AliOS Things 轻应用

AliOS Things Mini Program (AMP)

简介

AliOS Things轻应用是一套运行在资源受限设备上的轻量级应用软件框架。

业务应用代码脚本化,使用JavaScript脚本迅速构建轻应用。 嵌入式系统底座和应用完全解耦,使得IoT设备端应用生态的广度大幅拓宽。

Runtime采用JavaScript引擎加载用户脚本代码并执行,配合高可用的服务和工具提供应用的在线分发、更新及运维

  • Runtime采用JavaScript应用引擎加载用户脚本代码并执行,配合高可用的服务和工具提供应用的在线分发、更新及运维
  • 无需编译、烧录即可开发在物联网设备上运行的轻量级应用,快速开发,高效运维
  • 可通过云存储托管设备端应用和资源,也通过集成云服务API,使得云端计算能力获得在设备端的延伸

支持平台

轻应用框架支持各类os,已支持的典型平台有

  • linux
  • aos(AliOS Things)

移植说明

  • 适配层 系统适配代码在adapter目录中,结构如下
├── Config.in
├── Makefile            Linux平台编译文件
├── aos.mk              aos平台编译文件
├── include
│   ├── amp_pcm.h       音频PCM读写API
│   ├── aos_fs.h        文件系统API
│   ├── aos/kv.h        key,valueAPI
│   ├── aos_network.h   网络API
│   ├── aos_pm.h        电源管理API
│   ├── amp_httpc.h     HTTP Client
│   ├── aos_system.h    系统API
│   └── peripheral      外设API
└── platform
    ├── FreeRTOS-l610   l610适配参考
    ├── ThreadX-ec100y  ec100y适配参考
    ├── aos             AliOS Things适配参考
    └── linux           linux适配参考

适配层代码包含系统、网络、电源管理、音频、外设API等,移植请参考platform下已适配平台

  • 入口 AliOS Things 轻应用框架的主服务入口在 entry/amp_entry.c 中,调用 amp_main(), 即可启动轻应用服务,在你的项目工程中创建一个任务,将amp_main()注册进去即可。

  • 服务实现 轻应用服务包含两个主要线程,一个是建立网络通道,服务于热更新、在线运维等后台服务 另一个是脚本引擎服务线程,用来解析脚本引擎

使用说明

1. 获取服务账号并绑定设备

  • 联系SDK提供者获取账号token并绑定你的设备

2. 获取命令行工具amp

3. 编写应用代码

按如下目录结构,创建一个新应用

app                     应用目录
├── board.json          配置文件
└── index.js            应用入口

4. 应用代码热更新

AliOS Things轻应用框架使用热更新方式把应用代码推送到设备上,使用命令行工具amp以完成此功能。 命令用法例举如下

用户登录
$ amp login <token>
列出绑定设备
$ amp device list
推送脚本到指定设备
$ amp put ./app <device name>
