Jan 1, 2025January 2025 monthly summary for cmu-argus-2/FSW-mainboard focusing on business value and technical delivery. Key features delivered - CDH integration and state machine enhancements: introduced CDH messaging, pre-CDH transmission logic, updated comms statechart, centralized state machine, response queue, and merge from main. This improves command handling reliability and on-orbit responsiveness. - HAL cleanup for v2 mainboard: removed GPS_EN from HAL to simplify configuration and reduce risk, improving maintainability and future HAL updates. - IMU HAL planning: removed IMU name from reference and added a TODO for IMU HAL modification to guide upcoming work and issue tracking. - GPS task optimization for debugging: increased GPS task frequency to accelerate debugging cycles. - Comms/app maintainability: reformatted comms app for readability; planning tasks for comms latency characterization. Major bugs fixed - Bug fixes by Ibrahima: addressed multiple bug fixes deployed by Ibrahima. - Print bug fix in main: corrected a print-related issue in the main task. - Fuel gauge bug fixes: stabilized fuel gauge readings and behavior. - TM frame packing and 4-byte error limit fixes: corrected TM frame packing and tightened error value handling to respect 4-byte limits. - GPS memory allocation bug fix: resolved memory allocation failure associated with GPS usage when has_fix was altered. - Code quality and testing gaps: addressed linting issues and documented lack of unit tests, with improvements to code quality and maintainability. Overall impact and accomplishments - Improved system reliability and maintainability across the FSW mainboard, with a clearer plan for upcoming IMU HAL work and a more robust CDH integration path. - Enhanced debugging efficiency (GPS task frequency) and better code quality (lint fixes, cleaned up comms app). - Clear traceability of work through structured commits, enabling easier future merges and issue tracking. Technologies/skills demonstrated - Embedded C/C++, HAL layers, satellite comms architecture, CDH integration and state machine design, and centralized messaging. - Debugging and troubleshooting practices (latency planning, heartbeat tuning, memory management). - Code quality practices (linting, readability improvements, maintainability planning).

Dec 1, 2024December 2024 — cmu-argus-2/FSW-mainboard delivered reliability, testability, and maintainability improvements across key subsystems. Implemented modularized communications with separate TX/RX paths and enhanced heartbeat/timeouts, augmenting protocol robustness and telemetry observability across comms and EPS. Decoupled the emulator from the simulator to reduce dependencies and improve testability. Refactored the IMU driver to remove reliance on hardware name identifiers, added a flag-based IMU temperature availability check, and improved logging for cross-version compatibility. Completed a broad code-quality drive with linter fixes and formatting enhancements for configuration and thermal tasks. These changes reduce failure modes, improve hardware-variant compatibility, and accelerate validation and QA.
