PROFILE
Andrew
Andrew Freeman contributed to the concordia-fsae/firmware repository by developing and integrating key embedded systems features over four months. He enhanced motor controller CAN communication, introducing signal ID offset support and validation logic in C and YAML to improve data integrity and prevent configuration errors. Andrew implemented initial calibration data for pedal mapping, enabling more accurate drive-by-wire operation, and integrated a shockpot module for real-time suspension monitoring using analog input processing. He also extended the vehicle communication bridge to support new telemetry data types, leveraging C programming and CAN protocol expertise to improve system interoperability, reliability, and maintainability across vehicle subsystems.

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.
