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 replicable development environments for your entire team - no more struggling with toolchains and “it worked on my machine”


Turnkey solutions for new projects that want to make full use of everything that Pigweed offers

Who’s using Pigweed?#

Pigweed has shipped on millions of devices.

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!

What’s new in Pigweed#

Highlights (Mar 21, 2024 to Apr 4, 2024):

  • New modules: pw_i2c_rp2040 is a Pico SDK implementation of the pw_i2c interface, pw_async2_epoll is an epoll-based backend for pw_async2, pw_spi_linux is a Linux backend for pw_spi, pw_uart provides core methods for UART communication, and pw_bluetooth_proxy provides a lightweight proxy host that can be placed between a Bluetooth host and a Bluetooth controller to add functionality or inspection.

  • Docs updates: Pigweed’s main docs builder now builds the examples repo; the examples will be available at https://pigweed.dev/examples. An experimental complete Doxygen API reference is now being published to https://pigweed.dev/doxygen. The pw_i2c docs, reStructuredText style guide, and docs contributors homepage have been revamped.

  • Android platform updates: Many modules were refactored to follow the guidance in pw_build_android to make it easier to build them in Soong.

See Apr 4, 2024 in our changelog for details.
