Mohamed Mahmoud developed embedded systems features for the scsd-cdh/OBC repository, focusing on remote control, automation, and maintainability. He implemented an I2C-based telecommand framework and heartbeat monitoring system using C and MSP430 microcontroller programming, enabling master devices to query status, issue reboots, and monitor device health. His work included RTC-driven timers for scheduled shutdowns, interrupt-driven heartbeat management for automatic recovery, and telemetry integration for observability. Mohamed also improved codebase organization, introduced developer documentation, and standardized configuration templates using Makefile and YAML, laying a foundation for future modules. His contributions demonstrated depth in low-level programming and embedded firmware development.

May 2025 monthly summary for scsd-cdh/OBC focused on repo hygiene and scaffolding for future CDH configurations. Delivered a targeted feature that cleans and standardizes project structure, laying groundwork for future work and easier onboarding. Key outcomes include consolidated cleanup and refactor of the repository, removal of obsolete build artifacts and startup/config files, update of .gitignore to prevent accidental inclusion of ephemeral artifacts, and introduction of a new configuration template to standardize CDH project configurations. A start-up scaffolding artifact was added to guide future bootstrap processes. Commits supporting these changes include a2979486a8b4a90d8bac2a2677f0d10d922afafa ("clean up"), d508f3a59efd928b40b8d802466b2ac00324e02a ("cleanup2"), and a96189bc0e9f31304d3ca9d975cb0a7112129d0a ("added atstart file for future ref").

February 2025 monthly summary for scsd-cdh/OBC: Delivered the Heartbeat Monitoring and Auto-Reboot System, including enhanced RTC interrupt handling and telemetry-driven heartbeat management to improve reliability and uptime of the device fleet. The changes enable automatic reboot when heartbeats are missed and reset heartbeat status upon receipt of a valid heartbeat, with interrupt-driven timing refinements to ensure reliable processing.

January 2025: Delivered two key capabilities for the OBC platform, focusing on automation, safety, and observability. Implemented an RTC-based 24-hour timer for converters A and B to enable scheduled shutdowns, and added I2C telecommands and telemetry for PDS to support remote control and status monitoring via tinyprotocol. These changes include BSP RTC initialization/configuration and I2C/ADC peripheral initialization and telemetry channel setup, laying the groundwork for automated maintenance and telemetry-driven lifecycle management.

November 2024 focused on delivering a robust I2C-based remote-control framework for the MSP430 and strengthening repository maintainability and onboarding. Key outcomes include a modular I2C Slave Telecommand Framework with TinyProtocol, targeted I2C/TinyProtocol fixes and usage examples, comprehensive developer guidelines and PR templates, and codebase cleanup and reorganization to prepare for MRAM and power-control modules. These efforts enhance remote monitoring/control for deployed devices, accelerate contributor onboarding, and establish stronger development practices.
