roll: third_party/pigweed pw_status: Introduce StatusBase and rework Status StatusBase is a zero-cost CRTP status base class used to define Status-like objects with custom status codes. A designated code value represents success (ok()). This enables richer, domain-specific status semantics while preserving standard Pigweed error handling conventions, including PW_TRY, PW_CHECK_OK, and PW_ASSERT_OK. Custom status types can be defined using the PW_STATUS_TYPE macro or by subclassing StatusBase directly with CRTP. Custom status types are constructed from their Code. pw::Status is reworked to be a concrete final class that inherits from StatusBase<Status, PW_STATUS_OK>, retaining all canonical helper methods and implicit pw_Status interop. PW_TRY and PW_CHECK_OK continue to accept types implicitly convertible to pw::Status.

This repository contains a variety experiments to help inform various Pigweed policies, designs, and implementation behaviors.
Code in this repository is not reviewed to the standard of the main Pigweed repository, and generally speaking is untested and maintained on a best-effort basis. This is not a repository of “early access” Pigweed modules, but more so a sandbox for Pigweed contributors to collaborate on investigations. For more information, see the contribution guidelines for the experimental repository and where to land code.
DO NOT DEPEND ON THIS REPOSITORY IN ANY PRODUCTION PROJECT!
Clone this repo with --recursive to get all required submodules.
git clone --recursive https://pigweed.googlesource.com/pigweed/experimental
This will pull the Pigweed source repository into third_party/pigweed. If you already cloned but forgot to --recursive run git submodule update --init to pull all submodules.
The //pw_graphics folder contains some libraries for drawing to an RGB565 framebuffer and displaying it on various platforms.
The demo applications that make use of these libraries are:
First time setup:
git clone --recursive https://pigweed.googlesource.com/pigweed/experimental cd experimental . ./bootstrap.sh pw package install imgui pw package install glfw pw package install stm32cube_f4 pw package install pico_sdk
Compile:
gn gen out --export-compile-commands --args=" dir_pw_third_party_stm32cube_f4=\"$PW_PROJECT_ROOT/environment/packages/stm32cube_f4\" " ninja -C out
Flash:
openocd -f third_party/pigweed/targets/stm32f429i_disc1/py/stm32f429i_disc1_utils/openocd_stm32f4xx.cfg -c "program out/stm32f429i_disc1_stm32cube_debug/obj/applications/terminal_display/bin/terminal_demo.elf verify reset exit"
First time setup:
pw package install stm32cube_f7
Compile:
gn gen out --export-compile-commands --args=" dir_pw_third_party_stm32cube_f7=\"//environment/packages/stm32cube_f7\" " ninja -C out
Flash:
openocd -f targets/stm32f769i_disc0/py/stm32f769i_disc0_utils/openocd_stm32f7xx.cfg \ -c "program out/stm32f769i_disc0_debug/obj/applications/blinky/bin/blinky.elf verify reset exit"
Compile:
gn gen out --export-compile-commands --args=" dir_pw_third_party_imgui=\"$PW_PROJECT_ROOT/environment/packages/imgui\" dir_pw_third_party_glfw=\"$PW_PROJECT_ROOT/environment/packages/glfw\" " ninja -C out
Run:

Working displays:
First time setup:
pw package install pico_sdk
Compile:
gn gen out --export-compile-commands --args=' PICO_SRC_DIR="//environment/packages/pico_sdk" ' ninja -C out
Flash:
Using a uf2 file:
./out/rp2040/obj/applications/terminal_display/terminal_demo.uf2 to your Pi Pico.Using picotool:
picotool:picotool reboot -f -u
picotool load ./out/rp2040/obj/applications/terminal_display/bin/terminal_demo.elf picotool reboot
Using a Pico Probe and openocd:
This requires installing the Raspberry Pi foundation's OpenOCD fork for the Pico probe. More details including how to connect the two Pico boards is available at Raspberry Pi Pico and RP2040 - C/C++ Part 2: Debugging with VS Code
Install RaspberryPi's OpenOCD Fork:
git clone https://github.com/raspberrypi/openocd.git \ --branch picoprobe \ --depth=1 \ --no-single-branch \ openocd-picoprobe cd openocd-picoprobe ./bootstrap ./configure --enable-picoprobe --prefix=$HOME/apps/openocd --disable-werror make -j2 make install
Setup udev rules (Linux only):
cat <<EOF > 49-picoprobe.rules SUBSYSTEMS=="usb", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE:="0666" KERNEL=="ttyACM*", ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE:="0666" EOF sudo cp 49-picoprobe.rules /usr/lib/udev/rules.d/49-picoprobe.rules sudo udevadm control --reload-rules
Flash the Pico:
~/apps/openocd/bin/openocd -f ~/apps/openocd/share/openocd/scripts/interface/picoprobe.cfg -f ~/apps/openocd/share/openocd/scripts/target/rp2040.cfg -c 'program out/rp2040/obj/applications/terminal_display/bin/terminal_demo.elf verify reset exit'
Launching gdb*
~/apps/openocd/bin/openocd -f ~/apps/openocd/share/openocd/scripts/interface/picoprobe.cfg -f ~/apps/openocd/share/openocd/scripts/target/rp2040.cfg
gdb-multiarch -ex "target remote :3333" -ex "set print pretty on" out/rp2040/obj/applications/terminal_display/bin/terminal_demo.elf
arm-none-eabi-gdb can be used in place of gdb-multiarch above.
Setup NXP SDK:
Compile:
gn gen out --export-compile-commands --args=" pw_MIMXRT595_EVK_SDK=\"//environment/SDK_2_12_1_EVK-MIMXRT595\" pw_target_mimxrt595_evk_MANIFEST=\"//environment/SDK_2_12_1_EVK-MIMXRT595/EVK-MIMXRT595_manifest_v3_10.xml\" pw_third_party_mcuxpresso_SDK=\"//targets/mimxrt595_evk:mimxrt595_sdk\" " ninja -C out
Flash the MIMXRT595-EVK:
Follow the instructions to flash the MIMXRT595-EVK with the SEGGER J-Link firmware and using arm-none-eabi-gdb at https://pigweed.dev/targets/mimxrt595_evk/target_docs.html#running-and-debugging.
