概述
本文主要介绍基于vs-code + nRF Connect SDK编译nrf54l15dk MCU的项目，文章介绍了配置编译环境的方法：包括Toolchain和SDK，还介绍了创建项目的方法，并编译代码，还介绍整个Output文件的内容。
1 编译配置
1.1 编译环境
编译环境介绍：
nRF Connect SDK 版本： v2.9.1
toolchains版本： b620d30767
VS-CODE版本： 1.98.1
nRF Connect for VS Code Extension Pack 版本： 2024.9.5
1.2 VS-Code配置
1）nRF Connect 插件
打开VS Code，点击nRF Connect插件会出现如下页面
2）nRF SDK Toolchain
点击Manage toolchains系统会列出SDK Toolchain列表
3）nRF SDK SDK
点击Manage SDKS系统会列出SDK 的列表，选择需要的版本并安装该SDK
2 创建和编译项目
2.1 创建项目
点击如下图标创建项目，nRF SDK下有许多的Demo可供参考，可以选择合适的项目作为Demo项目。
笔者以light_dimmer项目为例作为测试项目，其在SDK中的位置如下：
C:\ncs\v2.9.1\nrf\samples\bluetooth\mesh\light_dimmer\创建完成项目后，可配置编译参数
2.2 编译项目
命名编译的output文件夹，然后点击如下图标进行代码编译
编译流程如下：
编译完成后，可以看见如下Log:
2.3 重新编译
如果需要重新编译该项目，点击如下图标，系统就会重新编译代码
3 编译信息
3.1 设备树信息
点击如下图标就可以看见系统的编译器信息
其具体信息如下，通过该UI，可以知道系统使用了哪些资源，同时也可以对这些资源进行编辑：
3.3 MCU资源消耗信息
在编译的板卡log信息中，可以看见编译代码的log
Memory region Used Size Region Size %age Used
FLASH: 333516 B 992 KB 32.83%
RAM: 60166 B 256 KB 22.95%
IDT_LIST: 0 GB 32 KB 0.00%
vs-Code还提供个一个统计列表，方便查看MCU消耗的资源：
1） ROM资源
2）RAM资源
3）MCU内存分布
4 项目配置信息
在Config目录下可以找到项目的配置信息
4.1 设备树文件
其包括两个头文件，开发这可以在该文件中设计系统的设备数据信息
4.2 KConfig文件
该文件重要负责管理MCU相关的资料，通过配置y/n就可以enable或者disable相关的功能。
3.3 .hex文件
编译器在编译完成代码后，会生成一个.hex文件，其具体地址如下：
4.3 Cmake文件
其内容包括加载的source code文件路径，SDK地址，项目名称等信息
5 编译log：
