roll: pigweed pw_rpc: Add callback writes to raw RPC call objects This adds a new API to pw_rpc's RawServerReaderWriter and RawClientReaderWriter which allows users to directly serialize their RPC payloads to the RPC system's encoding buffer instead of a requiring a copy from an externally-managed buffer. This type of direct encoding buffer access is already possible through the pwpb and nanopb RPC APIs through the use of callback members in their generated structs. Enabling it in raw_rpc provides better parity with these other protobuf libraries.

This repository contains a minimal example of a Bazel-based Pigweed project. It is a LED-blinking service (featuring RPC control!) for the Raspberry Pi Pico. It can also be run on any computer using the included simulator.
git clone https://pigweed.googlesource.com/pigweed/quickstart/bazel pw_bazel_quickstart cd pw_bazel_quickstart
The only dependency that must be installed is Bazelisk.
Bazelisk is a launcher for the Bazel build system that allows for easy management of multiple Bazel versions.
Instructions for installing Bazelisk can be found here.
To run the simulator, type: bazelisk run //apps/blinky:simulator_blinky
Then, in a new console, connect to the simulator using: bazelisk run //apps/blinky:simulator_console
To start, connect a Raspberry Pi Pico, Pico 2, or debug probe via USB.
To run on the Raspberry Pi Pico, type: bazelisk run //apps/blinky:flash_rp2040
Then, in a new console, connect to the device using: bazelisk run //apps/blinky:rp2040_console
Once connected with a console, RPCs can be sent to control the LED. Try running:
device.set_led(True) device.set_led(False) device.toggle_led() device.blink(blink_count=3)
bazelisk test //...
will run the unit tests defined in this project, such as the ones in modules/blinky/blinky_test.cc
.
bazelisk run @pigweed//targets/rp2040/py:unit_test_server
in one console followed by bazelisk test //... --config=rp2040
will also allow running the unit tests on-device.
Try poking around the codebase for inspiration about how Pigweed projects can be organized. Most of the relevant code in this quickstart (including RPC definitions) is inside modules/blinky
, with some client-side Python code in tools/console.py
.
