Pigweed#
Sustained, robust, and rapid embedded product development for large teams
Get started#
Understand the core components of Pigweed and determine whether Pigweed is a good fit for your project.
Explore key Pigweed features, such as hermetic building, full C++ code intelligence in VS Code, communicating with devices over RPC, host-side and on-device unit tests, and lots more in a guided walkthrough.
Fork our minimal, Bazel-based starter project to create a new Pigweed project from scratch. The project includes a basic blinky LED program that runs on Raspberry Pi Picos and can be simulated on your development host.
Set up a C++-based Zephyr project, set up GitHub Actions, integrate Pigweed into an existing Bazel project, and more.
What’s new in Pigweed?#
Highlights:
ValueFuture subclassing in pw_async2 - Attach request metadata to futures and resolve them conditionally.
Manage lists of pending futures with ValueListProvider - Resolve pending futures out-of-order, according to custom resolution logic.
Expanded metric types in pw_metric - New
TypedMetricsupport for 64-bit integers, floats, booleans, and tokenized metrics.FreeRTOS Rust bindings - Centralized FreeRTOS Rust FFI bindings in a single
no_stdcrate.STM32 Nucleo-64 board support - Upstream pw_kernel support for the STM32 NUCLEO-F103RB board.
And more! See What’s new in Pigweed: July 2026.
What is Pigweed?#
Over 150 libraries (“modules”) enabling you to use modern C++ and software development best practices without compromising performance, code size, or memory
Easier automated building, testing, and linting for Bazel, GN, and CMake projects
Hermetic and reproducible development environments for your entire team - no more struggling with toolchains and the “it worked on my machine” problem
Who’s using Pigweed?#
Pigweed has shipped in millions of devices, including Google’s suite of Pixel devices, Nest thermostats, satellites, and autonomous aerial drones.
Showcase: pw_console#
pw_console is our multi-purpose, pluggable REPL and log viewer. It’s designed to be a complete development and manufacturing solution for interacting with hardware devices via pw_rpc over a pw_hdlc transport. Gone are the days of hacking together a REPL and log viewer for each new project!
