roll: pigweed, pw_toolchain: pw_stream_uart_linux: Add Config struct The config struct only has two basic properties for configuring the UART - the baudrate, and a new property added by this change for enabling flow control. We opt to make the properties to the Config struct as std::optional to allow the user to "keep" the default behaviour / previously set tty behaviour. This maintains backwards compatability of this API and also more closely resembles the Linux tty interface.

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.
