roll: pigweed pw_containers: Resolve pw_allocator co-dependencies in Android.bp

* Add pw_allocator as a dependency of pw_containers.

  Many pw_containers libraries (e.g. pw_containers:deque) depend on
  pw_allocator, but pw_containers was missing a dependency on
  pw_allocator.

* Split out pw_containers_intrusive_lists from pw_containers.

  As it was, that would introduce a dependency cycle:

    pw_containers → pw_allocator → pw_containers → …

  While other containers depend on pw_allocator, intrustive lists are a
  *dependency of* pw_allocator. So adding this pw_containers ->
  pw_allocator dependency would introduce a cycle between the two.

  This splits out pw_containers_intrusive_lists into its own target
  (group).

  Then change pw_allocator to depend on pw_containers_intrusive_lists.

* Update pw_string to depend on pw_containers_headers.

  Then there would be another dependency cycle:

    pw_metric → pw_base64 → pw_string → pw_containers → pw_allocator
      → pw_metric → …

  pw_string:string only depends on pw_containers:common and
  pw_containers:iterator, so change that to pw_containers_headers which
  does not depend on pw_allocator.

* Update pw_metric to depend on pw_containers_headers and
  pw_containers_intrusive_lists.

 Then there would be another dependency cycle:

    pw_containers → pw_allocator → pw_metric → pw_containers → …

  pw_metric uses only pw_containers:intrusive_list and
  pw_containers:vector, so change that to pw_containers_headers and
  pw_containers_intrusive_lists.

* Update pw_tokenizer to depend on pw_containers_headers.

  Then there would be another dependency cycle:

    pw_allocator → pw_metric → pw_tokenizer → pw_containers
      → pw_allocator → …

  pw_tokenizer users only pw_containers:to_array, so change that to
  pw_containers_headers.

Pigweed: minimal Bazel example

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.

Getting the code

git clone https://pigweed.googlesource.com/pigweed/quickstart/bazel pw_bazel_quickstart
cd pw_bazel_quickstart

Dependencies

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.

Running on the simulator

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

Running on hardware

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

Controlling the LED

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)

Running unit tests on the host device

bazelisk test //... will run the unit tests defined in this project, such as the ones in modules/blinky/blinky_test.cc.

Running unit tests on hardware

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.

Next steps

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.
