[roll third_party/pigweed] pw_gpio: Add new module and interfaces NOTE: this module will be renamed `pw_digital_io` immediately in a follow-up change. The Digital IO interface represents individual GPIO lines that support some combination of input, output, and/or interrupt functionality. The choice of supported capability, and most other configuration details are left up to the backend implementation.

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.
