Release 0.4.0

[andrewdavidmackenzie]

I have just created release 0.4.0 and also published it to crates.io.

This release has been a long time coming due to Summer vacations, being busy in general, struggling to get GH Action for our release to build for armv7 and aarch64 working correctly and quite a lot of work on a Raspberry Pi Pico port.

Notable features and changes in this release include:

• Pre-built binaries for armv7 and aarch64 for different Raspberry Pi devices, easing the installation process for Pi users. See the release notes for install mechanisms or you can also use cargo install as before (if you have a rust toolchain installed) or cargo binstall to install the piggui and piglet binaries.
• Updated to rppal (crate for interacting with GPIO on Raspberry Pi) v2, that amoung other things used a hardware timestamp on Input pin edge transitions detected, for more timing accuracy.
• Added the ability for piggui (host GUI) to connect piglet (CLI, on Pi) via a TCP connection. Piglet will listen for connections via TCP or Iroh and accept the first to arrive, and when done, go back to listen for both again. Just supply the ip:port that piglet outputs to piggui, via the command line option or via the connect dialog.
• A lot of code changes in preparation for Pico version ("porky"), including changes in serialization crate used for network connections
• Proto version of the "porky" Raspberry Pi Pico implementation. With this release done I will go back and finish that as part of the plan for 0.5.0

I have quite a few issues in that 0.5.0 Milestone that are related to small UI improvements, code improvements or the Pico port and allow me to continue to learn new aspects of rust.

But the plan can change if we get user adoption and input, so please drop a message here if you are using pigg, or would like any particular enhancement, new feature or bug fixed.

Change List

Here is the change list I put together from the long list of commits!

Add TCP Connection method

• via CLI argument and via connect dialog
• tab the connect dialog to have Iroh and TCP in same dialog

Updated rppal

• Use release 0.19.0 of rppal, with v2 API
• Add a 1ms debounce by default
• more accurate timestamps from Pi hardware used to draw waveform

Cross compile for armv7 and aarch64 without using cross

Release now contains pre-built binaries for armv7 and aarch64 via cargo-dist

Many Dependencies updated

Features to compile with iroh, tcp, both or neither

UI layout fixes

• Reduce text size of other pick_list on Linux also
• When switched tabs, don't clear values
• When enter pressed in connect dialog, validate the input fields and try and connect
• Add hyperlink to dialog text
• Implement scrollbar for both views
• Allow Escape key to exit dialog
• Improve the dialog when user tries to exit with unsaved changes

Significant work done on Pi Pico version of piglet (called "porky")

• Changes in serialization, struct definitions, and code re-org to enable some code reuse across piggui, piglet and porky and ensure compatible std and no-std serializations/deserialization of structs
• Add porky build to CI
• Porky has ssid info built-in at compile time
• Add a small test config for a board connected to Pico
• Pass the pin numbering scheme from hw to UI as per Have layout react to pin layout field in HardwareDescription #397
• Implement GPIO on Pico, including correct use of GPIO 0 and 1
• Complete Pico GPIO pin descriptions

Added some automated texting of piggui, piglet and connecting to one from the other

Docs

• Add INSTALLING.md and link to it from README.md
• Add RELEASING.md
• Add release manual testing checklist issue template, that describes scenarios, test blocks and test matrix
