SmartDisplay ESP32-S3 v1.1.0 - Engineering Excellence & Hardware Showcase

🚀 What's New in v1.1.0

This release elevates the SmartDisplay project to a senior open-source engineering standard, introducing formal architectural decision records (ADRs), complete continuous integration (CI) automation with YAML linting, community developer experience templates, and real hardware showcases.

🧠 Architecture Decision Records (ADRs)

Documented formal engineering rationale and physics calculations in docs/ARCHITECTURE_DECISIONS.md:

• ADR-01: Display SPI Bus at 80 MHz vs 40 MHz ($921.6\text{ kb/frame}$, $11.52\text{ ms}$ DMA transfer time, securing >65% time budget for 30 FPS LVGL rendering).
• ADR-02: Passive BLE Proxy vs Active Tracking mode (2.4 GHz RF coexistence eliminating Wi-Fi drops and I2S audio jitter).
• ADR-03: Dynamic GPIO46 Power Gating for NS4168 Class-D amplifier (~20mA idle power savings and zero background hiss).
• ADR-04: LIFO 10-item notification queue ring-buffer for immediate glanceability of critical home alarms.
• ADR-05: Event-driven SNTP clock synchronization eliminating cyclic 10s CPU wake-locks.

⚙️ CI/CD & Automated Quality Gates

• Automated ESPHome Validation: GitHub Actions workflow (.github/workflows/ci.yml) validating both modular packages (smartdisplay.yaml) and single-file standalone (smartdisplay_standalone.yaml).
• YAML Linting: Integrated yamllint step with custom .yamllint.yml configuration ensuring clean formatting across the codebase.

🤝 Open Source Standards & DX

• Contributor Guide: CONTRIBUTING.md with Gitflow branching model, Conventional Commits specification, and architectural parity guarantees.
• Code of Conduct: CODE_OF_CONDUCT.md adhering to Contributor Covenant v2.1.
• GitHub Issue & PR Templates: Structured YAML forms for Bug Reports, Feature Requests, and PR verification checklists.

📸 Real Hardware Showcase & Social Banner

• Added real high-resolution photographs of the device in its circular desk enclosure:
  • Standby clock face with live weather and unread notification bell badge.
  • Full-screen notification cards.
  • Destructive action confirmation modal.
  • Live system diagnostics screen.
• High-resolution OpenGraph social preview banner (.github/assets/banner.png 1280x640).

🌐 Community Outreach

• devices.esphome.io: Ready-to-submit device catalog template in docs/community/devices_esphome_io_submission.md.
• Home Assistant Community: Comprehensive showcase post draft in docs/community/home_assistant_community_post.md.
