PROFILE
Alex Lu
Alex Lu developed and enhanced embedded firmware for the Formula-Electric-Berkeley/FEB_Firmware_SN4 repository, focusing on vehicle control and sensor data reliability. Over three months, Alex delivered features such as improved Ready-to-Drive transitions, robust CAN bus message handling, and safer charging states, using C and XML for microcontroller programming. He addressed system stability by refining initialization routines, resolving merge conflicts, and cleaning up legacy code. Alex also improved pedal sensor calibration and data processing, reducing false positives and enhancing driving behavior. His work demonstrated depth in firmware development, sensor calibration, and version control, resulting in a more maintainable and reliable codebase.

Jul 1, 2025Month: 2025-07 Key features delivered: - Brake and accelerator pedal data handling improvements: removed brake plausibility check to reduce false positives and improve driving behavior; fixed CAN message formatting for accelerator pedal data (acc0/acc1); minor cleanup by commenting out unused functions for reading individual accelerator pedals. Commit: 20aa1538ec42771fa7e09310603b06e35e5a4b87. Major bugs fixed: - Fixed CAN message formatting for accelerator pedal data (acc0/acc1); removed the brake plausibility path that could trigger false braking, improving reliability of pedal interpretation. Overall impact and accomplishments: - Enhanced driving feel and safety through more reliable pedal data processing and reduced false events; simplified codebase with targeted cleanup and a traceable commit history, enabling easier future maintenance. Technologies/skills demonstrated: - Embedded firmware development, CAN bus data handling, version control discipline and commit traceability, targeted code cleanup, and debugging of peripheral data paths.
