Hemo Alsaraj contributed to the vortexntnu/vortex-auv-embedded repository by developing modular embedded systems features over a three-month period. He built a Pico-based PWM generator controlled via I2C, supporting up to eight ESCs, and implemented a ROS-enabled sensor and thruster node using the ADS1115 ADC on the Orin platform. His work included establishing robust build system scaffolding with CMake and Makefile, integrating USART serial debug printing for improved observability, and enhancing documentation and error handling. Using C, C++, and Python, Hemo focused on maintainability and clear interfaces, delivering tested, field-ready firmware and configuration patterns that accelerated onboarding and reduced integration risk.
March 2025 focused on advancing the vortex-auv-embedded stack with two core deliverables: a Pico-based PWM generator controlled via I2C slave supporting up to eight ESCs, and a ROS-enabled PSM sensor/thruster node on Orin using ADS1115. The PWM solution reached final code and was tested/verified, with enhanced LED feedback and expanded error handling, while the ROS/PSM work established end-to-end driver and integration groundwork and improved ROS builds. All work emphasized maintainability, documentation, and readiness for field validation.

Month: 2024-11 Performance Summary for vortex-auv-embedded. Key features delivered: Implemented Embedded MCU project configuration scaffolding for gripper, motherboard, and telemetry MCUs, including per-MCU .gitignore templates, Makefile configurations, and device-specific configuration files to enable structured embedded software development. Commits: dd963b21a02b1f7f0fae416dd991752e80cb1c8d. Major bugs fixed: Reverted prior repository structure changes to a stable state, removing .gitignore and several README edits from MCU directories to restore a stable layout. Commit: bf341db54adc62eb4c21b00080449813230b4251. Overall impact: Provides a standardized, scalable foundation for embedded development, improves build reproducibility, onboarding, and maintenance across the MCU families, and reduces drift in repository structure. Technologies/skills demonstrated: Embedded systems configuration, Makefile-based build automation, Git branching and revert workflows, repository management, and configuration file templating. Business value: Faster onboarding, consistent builds, safer repository evolution, and clearer boundaries between MCU configurations.
