Mar 1, 2025Month: 2025-03 — Delivered core features, stabilized the codebase, and advanced hardware integration for FRC1640/2025-Code. Key outcomes include experimentation groundwork for signal processing (Moving Average and EMA threshold), Goober readiness and messaging workflow updates, and foundational project scaffolding to support a multi-language codebase. Code quality improvements standardized constants and naming conventions, reducing future maintenance cost. Hardware/sensor integrations were advanced through ToF Imager inclusion and ReefDetector IO improvements. A series of reliability fixes were completed to improve release stability, including guardrails for critical states (guillotine prevention), repository state hardening, and bug fixes around IO handling and sensor value interpretation. Overall, the month improved feature delivery speed, reliability, and cross-language collaboration readiness, enabling faster business value delivery in upcoming sprints.
