OpenHarmony无人机MAVSDK开源库适配方案分享

代码与思维2024-03-30 21:06

MAVSDK 是 PX4 开源团队贡献的基于 MavLink 通信协议的用于无人机应用开发的 SDK，支持多种语言如 C/C++、python、Java 等。通常用于无人机间、地面站与通信设备的消息传输。

MAVLink 是一种非常轻量级的消息传递协议，用于与无人机（以及机载无人机组件之间）进行通信。MAVLink 遵循现代混合发布-订阅和点对点设计模式，数据流作为主题发送/发布，而任务协议或参数协议等配置子协议是点对点的重传。其中 MAVLink 1 每个数据包只有 8 个字节的开销，包括开始标志和数据包丢弃检测。MAVLink 2 只有 14 字节的开销。由于 MAVLink 不需要任何额外的成帧，因此非常适合通信带宽非常有限的应用程序。

当我们想要在 OpenHarmony 上做无人机相关工作时，在通信方面需要面临 MAVLink 的移植适配工作。因此接下来我们将分享如何将 MAVSDK 移植至 OpenHarmony 系统当中。

MAVSDK Github 开源地址：GitHub - mavlink/MAVSDK: API and library for MAVLink compatible systems written in C++17

接下来讲解如何把 MAVSDK 开源库添加至 OpenHarmony 工程中进行编译。（此方法与其他开源库移植方法基本一致）

本次移植通过新建子系统 mavsdk，在子系统下添加名为 mavsdk 的组件，并在该组件下添加名为 MAVSDK 的模块，OpenHarmony 系统层级顺序如下：子系统-> 组件-> 模块，下文中将都以此为顺序进行叙述。

表 1：添加到工程后的目录结构

路径 描述
ohos/build/subsystem_config.json 子系统配置
ohos/productdefine/common/products/ohos-arm64.json 板级相关
ohos/third_party/MAVSDK/bundle.json 在子系统中添加组件配置
ohos/third_party/MAVSDK/BUILD.gn 三方库模块化，将其加入组件中的 gn 文件

subsystem_config.json

首先在 ohos/build/subsystem 中添加 subsystem 节点。

"mavsdk": {   
	      "path": "third_party/MAVSDK", 
   	      "name": "mavsdk"
	  }
​

ohos-arm64.json 文件

在 ohos/productdefine/common/products/ohos-arm64.json 文件中添加板级相关的信息。

"mavsdk:MAVSDK":{} 
​

如下图所示：

Bundle.json 文件

在 ohos/third 目录下添加 bundle.json 文件，以便系统可以添加名为 MAVSDK 的组件。

对于此文件要点如注释所见（编译时去除注释以保证配置文件整洁性）

        "deps": {
            "components": [ "jsoncpp",
                            "zlib"//此处添加了要用的三方库，后续的build.gn中还会有所体现。
        ],
            "third_party": ["jsoncpp",
                            "zlib"
        ]
        },

            "sub_component": [  "//third_party/mavsdk:MAVSDK",
                                "//third_party/mavsdk:mavsdk_test"],//此处添加了接下来要编译的组件，一个是代码主仓组件，一个是代码的测试文件组件
            "inner_kits": [],
            "test": ["//third_party/mavsdk:mavsdk_test"]
        }
    }
  }

BUILD.gn 文件

在完成上述步骤后，下面需要在 ohos/third 目录添加 BUILD.gn，根据不同的系统生成静态或者动态库，注意点如下：

文件 作用
build.make 生成目标的源文件
depend.make 需要依赖的其他 C 源文件
flags.make cflags 相关的一些标志
link.txt 链接库相关信息

① 注意移植时的 cflags、cflags 应从原始的编译文件（例如 cmake 过程中 build 的生成文件：在 cmake 生成 makefile 的过程中分析 build.make、depend.make、flags.make、link.txt 等得出三方库对应的依赖关系）中获取相关的标志位

② 注意移植的源文件及头文件地址可以使用当前 build.gn 所在路径下相对位置，例如/src 与 build.gn 在同一路径下则路径可以直接应用 src/....

③ 注意 deps 若引用的是组件内的其他模块，例如其他 build.gn 文件中的组件或当前 build.gn 中位于此 deps 前的其他组件可以使用 ":module 进行模块依赖，若是引用组件外的其他组件则需要使用 "bundle

import("//build/ohos.gni")  
import("//build/test.gni")

config("mavsdk_cflag_config") {
    #编译时的标志位
    cflags = 
            [

    ]
    part_name = "MAVSDK"
}

​

通过以上操作以后，就可以在 OpenHarmony 编译源码了：

./build.sh --product-name rpi4 --build-target=MAVSDK --ccache

编译完成以后可以在 out/rpi4/mavsdk/MAVSDK 目录下看到编译生成的 libmavsdk.z.so 文件。

同时，还可以在 ohos/out/rpi4/tests/unittest/MAVSDK/mavsdk_test/mavsdk_test 目录下看到我们编译的测试文件，如下所示：

接下来把编译完成的 so 及测试文件到 RPI4 开发板中，运行测试文件验证整个库的移植情况。
