-# 新建应用程序
-
-下方将通过修改源码的方式展示如何编写简单程序，输出“Hello OHOS！”。请在[获取源码](quickstart-lite-sourcecode-acquire.md)章节下载的源码目录中进行下述操作。
-
-1. 新建目录及源码。
-
- 新建**applications/sample/camera/apps/src/helloworld.c**目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改OHOS为World）。当前应用程序可支持标准C及C++的代码开发。
-
- ```
- #include
-
- int main(int argc, char **argv)
- {
- printf("\n************************************************\n");
- printf("\n\t\tHello OHOS!\n");
- printf("\n************************************************\n\n");
-
- return 0;
- }
- ```
-
-2. 新建编译组织文件。
-
- 新建**applications/sample/camera/apps/BUILD.gn**文件，内容如下所示：
-
- ```
- import("//build/lite/config/component/lite_component.gni")
- lite_component("hello-OHOS") {
- features = [ ":helloworld" ]
- }
- executable("helloworld") {
- output_name = "helloworld"
- sources = [ "src/helloworld.c" ]
- include_dirs = []
- defines = []
- cflags_c = []
- ldflags = []
- }
- ```
-
-3. 添加新组件。
-
- 修改文件**build/lite/components/applications.json**，添加组件hello\_world\_app的配置，如下所示为applications.json文件片段，"\#\#start\#\#"和"\#\#end\#\#"之间为新增配置（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
-
- ```
- {
- "components": [
- {
- "component": "camera_sample_communication",
- "description": "Communication related samples.",
- "optional": "true",
- "dirs": [
- "applications/sample/camera/communication"
- ],
- "targets": [
- "//applications/sample/camera/communication:sample"
- ],
- "rom": "",
- "ram": "",
- "output": [],
- "adapted_kernel": [ "liteos_a" ],
- "features": [],
- "deps": {
- "components": [],
- "third_party": []
- }
- },
- ##start##
- {
- "component": "hello_world_app",
- "description": "Communication related samples.",
- "optional": "true",
- "dirs": [
- "applications/sample/camera/apps"
- ],
- "targets": [
- "//applications/sample/camera/apps:hello-OHOS"
- ],
- "rom": "",
- "ram": "",
- "output": [],
- "adapted_kernel": [ "liteos_a" ],
- "features": [],
- "deps": {
- "components": [],
- "third_party": []
- }
- },
- ##end##
- {
- "component": "camera_sample_app",
- "description": "Camera related samples.",
- "optional": "true",
- "dirs": [
- "applications/sample/camera/launcher",
- "applications/sample/camera/cameraApp",
- "applications/sample/camera/setting",
- "applications/sample/camera/gallery",
- "applications/sample/camera/media"
- ],
- ```
-
-4. 修改单板配置文件。
-
- 修改文件**vendor/hisilicon/hispark\_taurus/config.json**，新增hello\_world\_app组件的条目，如下所示代码片段为applications子系统配置，"\#\#start\#\#"和"\#\#end\#\#"之间为新增条目（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
-
- ```
- {
- "subsystem": "applications",
- "components": [
- { "component": "camera_sample_app", "features":[] },
- { "component": "camera_sample_ai", "features":[] },
- ##start##
- { "component": "hello_world_app", "features":[] },
- ##end##
- { "component": "camera_screensaver_app", "features":[] }
- ]
- },
- ```
+# 编写“Hello World”程序
+下方将展示如何在单板上运行第一个应用程序，其中包括新建应用程序、编译、烧写、运行等步骤，最终输出“Hello World！”。
+
+
+## 示例目录
+
+示例完整目录如下：
+
+
+
+```
+applications/sample/hello
+│── BUILD.gn
+│── include
+│ └── helloworld.h
+│── src
+│ └── helloworld.c
+├── bundle.json
+│
+│── test
+│ └── moduletest
+│ └── unittest
+│
+productdefine/common
+└── products
+ └── Hi3516DV300.json
+```
+
+
+## 开发步骤
+
+请在源码目录中通过以下步骤创建“Hello World”应用程序：
+
+
+1. 创建目录，编写业务代码。
+ 新建applications/sample/hello/src/helloworld.c目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改World为OH）。其中helloworld.h包含字符串打印函数HelloPrint的声明。当前应用程序可支持标准C及C++的代码开发。
+
+
+ ```
+ #include
+ #include "helloworld.h"
+
+ int main(int argc, char **argv)
+ {
+ HelloPrint();
+ return 0;
+ }
+
+ void HelloPrint()
+ {
+ printf("\n\n");
+ printf("\n\t\tHello World!\n");
+ printf("\n\n");
+ }
+ ```
+
+ 再添加头文件applications/sample/hello/include/helloworld.h，代码如下所示。
+
+
+ ```
+ #ifndef HELLOWORLD_H
+ #define HELLOWORLD_H
+ #ifdef __cplusplus
+ #if __cplusplus
+ extern "C" {
+ #endif
+ #endif
+
+ void HelloPrint();
+
+ #ifdef __cplusplus
+ #if __cplusplus
+ }
+ #endif
+ #endif
+ #endif // HELLOWORLD_H
+ ```
+
+2. 新建编译组织文件。
+ 1. 新建applications/sample/hello/BUILD.gn文件，内容如下所示：
+
+ ```
+ import("//build/ohos.gni") # 导入编译模板
+ ohos_executable("helloworld") { # 可执行模块
+ sources = [ # 模块源码
+ "src/helloworld.c"
+ ]
+ include_dirs = [ # 模块依赖头文件目录
+ "include"
+ ]
+ cflags = []
+ cflags_c = []
+ cflags_cc = []
+ ldflags = []
+ configs = []
+ deps =[] # 部件内部依赖
+
+ part_name = "sample" # 所属部件名称，必选
+ install_enable = true # 是否默认安装（缺省默认不安装），可选
+ }
+ ```
+ 2. 新建applications/sample/bundle.json文件，添加sample部件描述，内容如下所示。
+
+ ```
+ {
+ "name": "@ohos/hello",
+ "description": "Hello world example.",
+ "version": "3.1",
+ "license": "Apache License 2.0",
+ "publishAs": "code-segment",
+ "segment": {
+ "destPath": "applications/sample/hello"
+ },
+ "dirs": {},
+ "scripts": {},
+ "component": {
+ "name": "hello",
+ "subsystem": "applications",
+ "syscap": [],
+ "features": [],
+ "adapted_system_type": [
+ "mini",
+ "small",
+ "standard"
+ ],
+ "rom": "10KB",
+ "ram": "10KB",
+ "deps": {
+ "components": [],
+ "third_party": []
+ },
+ "build": {
+ "sub_component": [
+ "//applications/sample/hello:helloworld"
+ ],
+ "inner_kits": [],
+ "test": [
+ "//applications/sample/hello/test:moduletest",
+ "//applications/sample/hello/test:unittest"
+ ]
+ }
+ }
+ }
+ ```
+
+ bundle.json文件包含两个部分，第一部分说明该子系统的名称，component定义该子系统包含的部件，要添加一个部件，需要把该部件对应的内容添加进component中去。添加的时候需要指明该部件包含的模块sub_component，假如有提供给其它部件的接口，需要在inner_kits中说明，假如有测试用例，需要在test中说明，inner_kits与test没有也可以不添加。
+
+3. 修改产品配置文件。
+ 在productdefine\common\products\Hi3516DV300.json中添加对应的hello部件，直接添加到原有部件后即可。
+
+
+ ```
+ "usb:usb_manager_native":{},
+ "applications:prebuilt_hap":{},
+ "applications:hello":{},
+ "wpa_supplicant-2.9:wpa_supplicant-2.9":{},
+ ```
