[roll third_party/pigweed] pw_software_update: Make OpenableReader::reader virtual OpenableReader is a wrapper around a StreamReader that needs open/close management. It exposes a method, `reader`, to access the reader, with the contract that this may only be used when the OpenableReader is open. OpenableReader stores a reference to the underlying reader inside of itself (and it must take the reference in the superclass constructor). However, it's entirely possible that the underlying StreamReader doesn't exist until Open is called (for example, if the underlying reader is a StdFileReader, reading from the filesystem). This commit addresses this use-case by making the `reader()` accessor virtual, and clarifies how it must be used in the header. This commit also adds a default virtual destructor to OpenableReader, which was missing.

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.
