Wrapping up the hardware stuff for now

Camera-Screen display

• Preview rendering on the round GC9A01 needed a lot of work.
• Updated how the camera feed gets displayed; cropping, scaling, etc. Attempting smooth transitions in and out of capture mode.
• The round display has its own constraints and getting things to look right on it takes more finagling than you’d think.

Button Feel

• Edge detection: rewrote the edge-detect logic to be more reliable. The previous version had some timing issues where you’d get double-fires or miss inputs under certain conditions.
• Reworked it to be cleaner about falling vs rising edge and the debounce behavior.
• Also cleaned up the client detection that feeds into button handling — when you press the button and there’s no active client on the AP, the fallback behavior now handles that gracefully.

Plugins

• Exposed a few more configuration knobs through the CLI and settings.py — things like LED brightness and behavior tuning that were previously hardcoded in the plugin.
• If you’re running this on different hardware or in different lighting conditions you’d want to be able to dial those in pretty easily.

That’s about it for the initial build. The thing runs, processes photos, it has a GPS map, it works as a headless Pi module with a round display and a button and some LEDs. Nobbad for a couple days work.
