Developed and integrated support for the PMW3901 optical flow sensor within the Hyp-ed/hyped-2025 repository, focusing on embedded systems and sensor integration using Rust. Implemented an SPI driver and sensor initialization logic to enable accurate motion detection, and created a dedicated test binary to validate sensor performance. Updated project dependencies and board configurations to ensure seamless hardware compatibility and facilitate future sensor fusion efforts. The work emphasized robust driver development and low-level SPI communication, laying the groundwork for improved navigation accuracy. No bug fixes were recorded during this period, with efforts concentrated on delivering a complete and functional feature integration.
