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 (Jan 26, 2024 to Feb 9, 2024):

  • The new pw_grpc module provides classes that map between pw_rpc packets and HTTP/2 gRPC frames, allowing pw_rpc services to be exposed as gRPC services.

  • A lot of the remaining pw_toolchain_bazel feature work from 0113: Add modular Bazel C/C++ toolchain API was finished and rough edges were polished up.

  • The new generic pw::allocator::BlockAllocator interface supported several derived types that enable fine-grained control over how a block satisfies an allocation request.

  • pw_transfer now supports resumable transfers.

See Feb 9, 2024 in our changelog for details.
