Get VSCode + plugin.
Or go Linux.
Seriously.
Or wsl.
EOF.


Hard way, git, MS Visual Studio(not VSCode):

 As in:
"Getting started with Raspberry Pi Pico-series
C/C++ development with Raspberry Pi Pico-series and other
Raspberry Pi microcontroller-based boards"
=> https://www.raspberrypi.com/documentation/microcontrollers/c_sdk.html


 Setup
 Get sdk and examples:
```
cd C:\c\pico
git clone https://github.com/raspberrypi/pico-sdk.git^
 --branch master

cd pico-sdk
git submodule update --init
cd ..
git clone https://github.com/raspberrypi/pico-examples.git^
 --branch master
```

 Get toolchain, and decrunch them into eg.: C:\c\pico
=> https://github.com/raspberrypi/pico-sdk-tools/releases/download/v2.2.0-2/openocd-0.12.0+dev-x64-win.zip
=> https://github.com/raspberrypi/pico-sdk-tools/releases/download/v2.2.0-2/pico-sdk-tools-2.2.0-x64-win.zip
=> https://github.com/raspberrypi/pico-sdk-tools/releases/download/v2.2.0-2/picotool-2.2.0-a4-x64-win.zip
=> https://github.com/raspberrypi/pico-sdk-tools/releases/download/v2.2.0-2/riscv-toolchain-15-x64-win.zip

 Get cmake 3.31.10, not newer: cmake-3.31.10-windows-x86_64.zip
=> https://cmake.org/download/

Run VS Developer Console assuming you have visual studio, not code
```
set PATH=C:\c\cmake\cmake-3.31.10-windows-x86_64\bin;^
%PATH%;^
C:\c\pico\pioasm;^
C:\c\pico\picotool;^
C:\c\pico\riscv-toolchain-15-x64-win\bin
```

I have devkitpro cmake in %PATH%, so cmake path goes before %PATH%
```
set PICO_SDK_PATH=C:\c\pico\pico-sdk
```

You can use setx/system env variables change for permanent clutter

Build
```
cd c:\c\pico\pico-examples\build
cmake -DPICO_PLATFORM=rp2350-riscv -DPICO_BOARD=pico2 ..
cd blink
nmake
```

Voi-and-la.

No idea how to use amd64 windows clang or gcc.

This seems to not work at all:
```
set PICO_RISCV_TOOLCHAIN_PATH=c:\c\pico\riscv-toolchain-15-x64-win\bin
```

Now, I should definitely buy a Pico.
