Getting Started

Make sure you've set up Pigweed's prerequisites.

If you're on Windows, you can automate the initial setup by downloading the first-time setup script from cmd.exe:

curl https://pigweed.googlesource.com/pigweed/sample_project/+/main/tools/setup_windows_prerequisites.bat?format=TEXT > setup_pigweed_prerequisites.b64 && certutil -decode -f setup_pigweed_prerequisites.b64 setup_pigweed_prerequisites.bat && del setup_pigweed_prerequisites.b64

Then you can run the script with the following command in cmd.exe:

setup_pigweed_prerequisites.bat

Note: You may see a few UAC prompts as the script installs Git, Python, and enables developer mode.

Once that is done, you can clone this project with the following command:

git clone https://pigweed.googlesource.com/pigweed/kudzu

Environment setup

Pigweed uses a local development environment for most of its tools. This means tools are not installed to your machine, and are instead stored in a directory inside your project (Note: git ignores this directory). The tools are temporarily added to the PATH of the current shell session.

To make sure the latest tooling has been fetched and set up, run the bootstrap command for your operating system:

Windows

bootstrap.bat

Linux & Mac

source ./bootstrap.sh

After tooling updates, you might need to run bootstrap again to ensure the latest tools.

After the initial bootstrap, you can use use the activate scripts to configure the current shell for development without doing a full update.

Windows

activate.bat

Linux & Mac

source ./activate.sh

Device tools setup

Install the pico SDK and tool to flash the device.

pw package install pico_sdk
pw package install picotool

These packages will be built and added to the path automatically. There is no need to add these to the gn arguments.

Linux Setup

GLFW Dependency:

Install the GLFW OpenGL library

sudo apt install libglfw3-dev libglfw3

Udev Rules:

Put the following into /usr/lib/udev/rules.d/49-picoprobe.rules

# Pico app mode
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="000a", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="000a", MODE:="0666", SYMLINK+="rp2040"

# RP2 Boot
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0003", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0003", MODE:="0666", SYMLINK+="rp2040"

# Picoprobe
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE:="0666", SYMLINK+="picoprobe"

This will also symlink /dev/picoprobe and /dev/rp2040 to the respective vendor and product ids.

Apply the above rules with:

sudo udevadm control --reload-rules
sudo udevadm trigger

Compile:

pw build

Run:

Host

Run the host app and connect to it via pw-system-console:

./out/gn/host_device_simulator.speed_optimized/obj/applications/badge/bin/badge & \
  pw-system-console --socket-addr default \
    --proto-globs third_party/pigweed/pw_rpc/echo.proto ; \
  killall badge

Kudzu

export ELF=./out/gn/rp2040.size_optimized/obj/applications/badge/bin/badge.elf

picotool reboot -f -u && \
  sleep 3 && \
  picotool load -x $ELF

Connect with pw-system-console:

pw-system-console --verbose \
  --baudrate 115200 \
  --proto-globs third_party/pigweed/pw_rpc/echo.proto \
  --token-databases ./out/gn/rp2040.size_optimized/obj/applications/badge/bin/badge.elf \
  --device /dev/rp2040
