We're pleased to communicate the second release of the "pigg" project, with focus on the "piggui" GUI.

What is "piggui"

Piggui is a GUI for interacting with Raspberry Pi GPIO hardware, controlling outputs and observing inputs.

What's new in Release v0.2.0

Addition of a squarewave moving window view of inputs and outputs
Button to easily make quick changes to an Output level, maintaining toggler for setting longer term level
LED view added to Output to resemble more the Input view
Styling to improve visuals of Output toggler
Warnings to help avoid losing work if attempting to exit prior to saving.
Addition of a status bar at the bottom of the UI with
- Version number and About pop-up when clicked
- Hardware name and hardware details pop-up when clicked
- Unsaved changes indicator that opens save dialog when clicked
- Info messages, Warnings and Errors shown color-coded in status bar
Moving of hardware details to pop-up has cleaned the UI and permitted a slightly smaller window
Improved error handling, reporting info, warnings and errors to status bar
Fullscreen is working on macos and linux (unable to test on windows)

Refactored UI code into views, widgets, styles simplifying a lot the main update() and view() methods and making the project easier to contribute to and more maintainable
Added tests and increased test coverage
Reviewed pin definitions against BCM2711 chip datasheet used in Raspberry Pi 4. This changes the defaults for Input pull-ups and clarifies the other ALT functions (still in comments for now).
