Worked on the masa-umich/Rocket-Avionics repository to integrate the MS5611 sensor into an embedded avionics system, focusing on reliable altitude measurement. Developed a structured register map by defining sensor command and address constants in C, enabling precise communication with the hardware. Implemented altitude calculation within the driver using an oversampling ratio to enhance accuracy, and exposed this data through a dedicated getAlt function for telemetry purposes. The work emphasized driver development and sensor integration, laying a foundation for robust altitude sensing and smoother interaction with higher-level flight software. Documentation and code structure were prepared for future reset and update flows.
