Going to do a complete rewrite as this doesn't work on Zig 0.10.x, archiving.

Zig on the Raspberry Pi Pico without losing access to the SDK.

Install the Pico SDK dependencies

sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib

Clone the Pico SDK

git clone https://github.com/raspberrypi/pico-sdk path/to/pico-sdk

Make sure PICO_SDK_PATH is set

export PICO_SDK_PATH path/to/pico-sdk

Check build.zig and example/main.zig, it's fairly self explanatory.

To build the example for the Pico W

zig build

If you have picotool installed, load the resulting uf2 file

picotool load -f zig-out/uf2/pico-app.uf2

• integrate cmake into zig build
• add include paths of pico libraries to app
• optimize cmake build steps
• wrap pico-sdk functions into Pkgs
• ???
• profit
