[roll third_party/pigweed] pw_span: Introduce pw::span - pw::span is identical to Pigweed's polyfilled std::span, but in a different namespace. Implicit converions between std::span and pw::span are supported inherently. pw::span and std::span are maintained as separate classes, with shared code in a .inc file. This is done instead of aliasing since C++17 does not support class template argument decuction with aliases. Also, it is simpler to have separate implementations to avoid circular dependencies while migrating code to pw::span. - Add DEFINES to the pw_add_test() CMake function to support defining preprocessor macros for the pw_span test. - Move '.inc' and '.inl' extensions from CPP_HEADER_EXTS to CPP_SOURCE_EXTS, since these should be treated like sources not headers (no include guards).

This repository contains experimental pigweed modules.
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
Compile:
gn gen out --export-compile-commands --args=" dir_pw_third_party_stm32cube_f4=\"$PROJECT_DIR/.environment/packages/stm32cube_f4\" " ninja -C out
Flash:
openocd -f third_party/pigweed/targets/stm32f429i_disc1/py/stm32f429i_disc1_utils/openocd_stm32f4xx.cfg -c "program out/stm32f429i_disc1_stm32cube_debug/obj/applications/terminal_display/bin/terminal_demo.elf verify reset exit"
Compile:
gn gen out --export-compile-commands --args=" dir_pw_third_party_imgui=\"$PROJECT_DIR/.environment/packages/imgui\" " ninja -C out
Run:
out/host_debug/obj/applications/terminal_display/bin/terminal_demo
Clone the pico-sdk repo:
cd $HOME git clone https://github.com/raspberrypi/pico-sdk
Compile:
gn gen out --export-compile-commands --args=" PICO_SRC_DIR=\"$HOME/pico-sdk\" " ninja -C out
Create a uf2 file for flashing the Pico with:
./out/host_debug/obj/targets/rp2040/bin/elf2uf2 ./out/rp2040/obj/applications/terminal_display/bin/terminal_demo.elf ./out/rp2040/obj/applications/terminal_display/bin/terminal_demo.uf2
Copy ./out/rp2040/obj/applications/terminal_display/bin/terminal_demo.uf2
to your Pi Pico.
