2. 工具安装与验证
2.1 工具安装
winget安装依赖工具（Windows Package Manager）
以 管理员身份 打开 cmd.exe或者PowerShell，运行：
winget install Kitware.CMake Ninja-build.Ninja python Git.Git 7zip.7zip Arm.GnuArmEmbeddedToolchainwindows安装包下载临时目录

已成功安装GCC/Make安装
从http://www.equation.com/servlet/equation.cmd?fa=fortra 下载gcc套件，gcc套件内包含make，因为编译picotool需要gcc所以一并就装了这俩。
解压gcc套件，比如默认按照在了个人账户目录内为 C:\Users\Administrator\gcc 。
ARM GNU Toolchain:
arm-gnu-toolchain-14.2.rel1-mingw-w64-x86_64-arm-none-eabi.zip
7z.exe x "arm-gnu-toolchain-14.2.rel1-mingw-w64-x86_64-arm-none-eabi.zip" -o"arm-gnu-toolchain-14.2" -y2.2 工具验证
验证方法：
命令行中输入以下指令，会打印出版本信息
make -v
GNU Make 4.3cmake --version
cmake version 4.0.2git -v
git version 2.49.0.windows.1python -V
Python 3.12.11arm-none-eabi-gcc -v
3 SDK环境搭建
3.1 官方参考文档
在github中获取树莓派pico的sdk和example（内容可参考树莓派pico提供的资料）
pico/getting-started-with-pico.pdf
pico/pico-datasheet.pdf
pico/raspberry-pi-pico-c-sdk.pdf
pico/raspberry-pi-pico-python-sdk.pdf
rp2040/hardware-design-with-rp2040.pdf
rp2040/rp2040-datasheet.pdf
3.2 SDK源码获取
可通过官网获取以下信息
sdk github链接https://github.com/raspberrypi/pico-sdk
example github链接https://github.com/raspberrypi/pico-examples
通过git下载好sdk和example，进入pico-sdk中，git执行此条指令
git submodule update --init该过程是更新sdk中第三方的库，例如usb、wifi等，更新内容在pico_sdk lib文件夹
3.3 编译
首先添加一下sdk环境变量将pico-sdk的文件路径添加PICO_SDK_PATH。
进入pico-examples参考工程目录
# 进入pico-examples文件夹中
cd D:\workspace\raspberrypi\pico-examples\
# 创建build目录
mkdir build
# 进入到build目录
cd build
# 生成Makefile文件
D:\workspace\raspberrypi\pico-examples\build>cmake -G "MinGW Makefiles" ..
Using PICO_SDK_PATH from environment ('D:\workspace\raspberrypi\pico-sdk')
PICO_SDK_PATH is D:/workspace/raspberrypi/pico-sdk
Defaulting platform (PICO_PLATFORM) to 'rp2040' since not specified.
Defaulting target board (PICO_BOARD) to 'pico' since not specified.

到此，整个树莓派pico的基础环境就算搭建完成啦。
