Worked on the oss-slu/Pi4Micronaut repository to deliver a robust four-digit seven-segment display subsystem, integrating Micronaut and Pi4J for seamless hardware control and API interaction. Over two months, developed and refactored display logic to decouple hardware dependencies, introduced multi-pin digital output configuration, and established groundwork for I2C integration. Enhanced testability through hardware-agnostic stubs and expanded unit tests, while improving maintainability with code cleanup and comprehensive documentation. Leveraged Java, YAML, and Mockito to ensure reliable value parsing, validation, and error handling. These efforts resulted in a scalable, maintainable display solution with clear wiring mappings and testable interfaces for IoT applications.

Nov 1, 2024November 2024 monthly summary for oss-slu/Pi4Micronaut. Focused on delivering a scalable Four-Digit Seven-Segment display solution and strengthening hardware integration with Pi4J and I2C, while improving testability and maintainability. Key outcomes include decoupling the 4-digit display logic from hardcoded paths, implementing multi-pin digital output configuration and factory-generated configurations, and enabling separate segment outputs for finer control. The month also advanced I2C groundwork inspired by CrowPi examples and laid the path for deprecating legacy multi-pin configurations to reduce technical debt. Through core display enhancements, targeted testing (servo, error handling, try-catch, and display/configuration tests), code cleanup, and extensive documentation, the team delivered tangible progress toward a robust, hardware-ready display subsystem with clear wiring mappings and testable interfaces.

Oct 1, 2024October 2024 (2024-10) monthly summary for oss-slu/Pi4Micronaut. Delivered end-to-end support for a four-digit seven-segment display with a Micronaut-based API integration and hardware control. Key deliverables include a new endpoint to render numbers on the four-digit display, refactored display helpers for per-digit control, updated GPIO mappings and leading-zero rendering, and robust value handling with validation and tests. The effort also included an expanded test suite and minor quality fixes to log initialization, improving reliability and maintainability. These changes enable reliable hardware UI feedback for devices in the Pi4Micronaut stack and establish a foundation for future display features and automation.
