HUAWEI DevEco Device Tool

以插件的形式部署在Visual Studio Code上

开发环境部署

步骤1 安装 vs code

Visual Studio Code - Code Editing. Redefined

步骤2 DecEco Device Tool 下载安装

华为集成开发环境IDE DevEco Device Tool下载 | HarmonyOS设备开发

解压后安装
选择安装路径

安装完成后打开vs code可以发现扩展图标

在这里插入图片描述

步骤3 下载Hi3861 Openharmony SDK

https://gitee.com/wgm2022/hi3861_for_AI_topic

步骤4 下载开发者工具

https://hispark.obs.cn-east-3.myhuaweicloud.com/DevTools_Hi3861V100_v1.0.zip

解压后目录
在这里插入图片描述

步骤5 工程管理配置

1. 打开DevEco Device Tool 主页导入工程

在这里插入图片描述

2. 选择Hi3861 Openharmony SDK目录

4. 进行后续代码开发、编译、烧录

Pegasus相关代码路径：

hi3861_for_AI_topic-master\src\vendor\hisilicon\hispark_pegasus\demo\

步骤6 编译、烧录

1. 配置开发工具路径

点击工程配置，配置compiler_bin_path选项为下载好的开发工具目录

测试程序-led闪烁

1. 创建子模块文件夹

在hi3861_for_AI_topic-master\src\applications\sample\wifi-iot\app目录下创建led_demo文件夹

2. 子模块程序编写

led_demo文件夹中的文件结构如下

3. 修改工程配置文件

修改hi3861_for_AI_topic-master\src\applications\sample\wifi-iot\app目录下的BUILD.gn文件

import("//build/lite/config/component/lite_component.gni")

lite_component("app") {

        "led_demo:ledDemo",
    ]

4. 编译、烧录

烧录、重启后即可看到板载led灯闪烁
