Raytheon Senior Project

This project discusses the development of a system that enables average smartphone users to transfer files directly from USB Mass Storage Devices to Android phones. The project outlines the requirements, design specifications, and analysis of utilizing the V2DIP2-48 USB host controller. Collaborations with Raytheon experts provided essential project supervision and technical support. Key features include programmable firmware support for FAT file structures, a user-friendly interface, and the use of the Android Open Accessory Development Kit. The goal is to create a seamless file transfer experience for users.
