Contributed to the CURocketEngineering/Avionics repository by enhancing telemetry data logging and improving hardware reliability in embedded systems. Developed a launch-number-based file naming convention and included servo angle data in telemetry logs, enabling more precise flight event analysis and better post-flight traceability. Addressed SD card initialization issues by correcting pin configuration, which improved logging stability and reduced the risk of data loss. Adjusted API visibility for flight status to facilitate integration and testing. All work was implemented in C++ with a focus on data logging, file management, and hardware interaction, laying groundwork for future enhancements in avionics data systems.
