Ethan Dean developed core embedded software for the UVicSatelliteDesign/COMP_SLIP-OBC repository, focusing on real-time data acquisition, power management, and robust subsystem coordination. He engineered features such as RTOS-based task scheduling, camera image capture with mutex-based concurrency, and dynamic low-power modes to optimize energy usage and data reliability. Using C and ARM Cortex-M microcontrollers, Ethan implemented hardware abstraction layers, error handling, and flash/SD storage interfaces to support autonomous telemetry and diagnostics. His work emphasized maintainability and operational transparency, introducing granular notification protocols and structured diagnostics, resulting in a scalable, power-aware firmware foundation for satellite on-board computer operations.

Jul 1, 2025Month: 2025-07 Key focus: Implemented and stabilized the Camera Image Capture feature for the UVicSatelliteDesign/COMP_SLIP-OBC repository, laying groundwork for autonomous data collection and power-aware operation. Key achievements: - Implemented Camera Image Capture Feature with a dedicated camera task and mutex-based synchronization to ensure safe concurrent access. - Removed idle state and introduced image_capture_in_progress and related state handling to improve responsiveness and reliability. - Defined image capture intervals to enable predictable data collection and support nominal and low-power modes. - Prepared a robust foundation for the imaging pipeline, enabling future enhancements with minimal risk to ongoing operations. Major bugs fixed: - No major bugs documented for this month in this repository. Focused on feature delivery and stability improvements for concurrency and power management. Overall impact and accomplishments: - Enables autonomous image capture with safer concurrent access, improving data yield and operational readiness for the satellite subsystem. - Power-aware design with defined capture intervals and mode support reduces energy consumption while maintaining data cadence. - Clear task separation and state handling reduce deadlock risk and simplify future maintenance. Technologies/skills demonstrated: - Embedded real-time systems concepts: task creation, concurrency with mutexes, and state management. - Power management and low-power mode considerations. - Code refactoring to remove idle state and improve system responsiveness. - Documentation-ready changes with clear commit messages and maintainable interfaces.
