The Naïve display GUI for Arduino

Executive Summary

Developer glutio has published Focuspocus on GitHub, a small GUI library for Arduino projects with a display. It provides buttons, labels, checkboxes, radio buttons, sliders, progress bars and popups, with automatic layout, touch input and button-driven focus navigation. The library adds about 12 to 16 KB of flash. The simple TFT examples fit on an Uno, with HelloButton using 93 percent, so a Mega, Nano Every, or a 32-bit board like SAMD, ESP32 or RP2040 leaves room for the rest of a sketch.

Open Silicon & Gate-Level Hardware Inspection

From a silicon and hardware engineering viewpoint: - **Interface Neutrality:** Mitigates dependency on proprietary BSPs, empowering open toolchains to address hardware directly. - **Supply Chain Verification:** Schematics and open pinouts allow deterministic audits against silicon errata. - **Lifecycle Decoupling:** Decouples physical hardware utility from commercial vendor end-of-life obsolescence.

Impact on the Open Ecosystem

Ensures that computational autonomy remains in the hands of the architect rather than closed silicon vendors.
