PROFILE
Andrew
Andrew Freeman contributed to the concordia-fsae/firmware repository by developing and integrating key features for embedded automotive systems over five months. He enhanced motor controller CAN communication, implemented APPS calibration for accurate pedal mapping, and integrated a shockpot module for real-time suspension monitoring. Using C, Python, and YAML, Andrew focused on robust configuration management, data modeling, and hardware integration to improve system reliability and data integrity. His work included extending the vehicle communication bridge for broader telemetry and diagnostics, as well as refining CAN signal resolution for ECUMaster compatibility. Each feature demonstrated careful attention to validation, maintainability, and cross-system interoperability.

Aug 1, 20252025-08 monthly summary: Focused on extending the Vehicle Communication Bridge in concordia-fsae/firmware to support new data definitions for Temperature, Motor Position, and Torque. This enables data exchange from the 'ass' (auxiliary) system to the 'veh' (vehicle) bus, enhancing telemetry, diagnostics, and cross-subsystem visibility. The feature was delivered via a single change set that added bridge messages (commit: c457d9f89db256f93da6c7022b0bf82599abb2e6). No major bugs fixed this month; where applicable, minor issues were reviewed and logged for upcoming sprints. Tech stack and skills demonstrated include embedded firmware development, bridge configuration, message bus design, data schema evolution, and Git-based collaboration with clear, traceable commits for future audits.

Jun 1, 2025June 2025 performance summary for concordia-fsae/firmware: Delivered foundational APPS calibration data for VCFRONT pedal mapping and fault thresholds, enabling more accurate pedal position readings in the front-end system. Updated mapping points and fault thresholds for APPS1 and APPS2 based on the initial calibration pass. These changes improve drive-by-wire fidelity, reduce false fault conditions, and provide a solid base for further calibration iterations.
