roll: pigweed pw_watch: Bazel run support Hook up enough bazel to be able to run pw_watch or pw_build through bazel run commands. For example: Run watch: bazelisk run //pw_watch/py:watch Run a single build (same as watch but only once then exit). bazelisk run //pw_build/py:project_builder Run the upstream project builder (optionally with --watch): bazelisk run //pw_build/py:pigweed_upstream_build -- \ -r default_bazel -r default_gn --watch Original-Bug: 360140397 Original-Reviewed-on: https://pigweed-review.googlesource.com/c/pigweed/pigweed/+/242094 Presubmit-Verified: CQ Bot Account <pigweed-scoped@luci-project-accounts.iam.gserviceaccount.com> Original-Revision: 5e7d1a0fddab1204d94ff43cee833431eda75af8 Rolled-Repo: https://pigweed.googlesource.com/pigweed/pigweed Rolled-Commits: e9391cf5d40a89..5e7d1a0fddab12 Roll-Count: 1 Roller-URL: https://cr-buildbucket.appspot.com/build/8733430481639409697 GitWatcher: ignore CQ-Do-Not-Cancel-Tryjobs: true Change-Id: I40436614515cdc938882b52e79fa89310ec0e03e Reviewed-on: https://pigweed-review.googlesource.com/c/pigweed/quickstart/bazel/+/243753 Commit-Queue: Pigweed Roller <pigweed-roller@pigweed-service-accounts.iam.gserviceaccount.com> Lint: Lint 🤖 <android-build-ayeaye@system.gserviceaccount.com> Bot-Commit: Pigweed Roller <pigweed-roller@pigweed-service-accounts.iam.gserviceaccount.com>
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
.
