Update

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

Zig on the Raspberry Pi Pico

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

Requirements

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

Usage

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

Build

To build the example for the Pico W

zig build

Running

If you have picotool installed, load the resulting uf2 file

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

Todo

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