Preliminary Design Review Jan 31, 2006 Brianna Bethel Robert Havlik Jessica Lowry Alex Silva

Market and Solution The Market –Sharing pictures requires large, inconvenient photo albums or stationary computers that are not easily accessible The Solution –To create a standalone, portable, easy-to-use system to display pictures without a computer

Potential Applications Sharing photos –Nursing homes –Hospitals –Infants in a Baby Crib –Home or Office Presentations Education Map Displays

Project’s Functionality Functions similarly to traditional picture frame Capable of displaying still-pictures and pictures in a slideshow format

Baseline Objectives Stores and retrieves pictures from SD and Compact Flash cards Displays pictures on color LCD screen Includes user interface Runs on an embedded version of Linux Incorporates CPLD

Possible Extensions Incorporate USB to upload and download pictures Control slideshow with a remote control that uses infrared (IR) technology Enable user to zoom in and out of images through a touchscreen interface Increase functionality with a FPGA

Outline of the Approach Industrial Development Process –Logic Product LH79524 Development Board “Less time, less risk, less cost...more innovation!” (Logic PD) –Simultaneous Hardware and Software Development Development Board Custom HardwareFinal Product!

Schedule

Key Events By CDR –Microcontroller with Linux Loaded –Custom PCB ready for component placement –STN LCD adapter fabricated and built By Milestone 1 –Have first PCB revision tested –Compact Flash working –Display still picture

Key Events By Milestone 2 –Second PCB revision tested –Implement user interface –Slideshow mode implemented Capstone Expo –Refine user interface –Demo Project

Risks and Contingency Plan Custom PCB –Unfamiliar technology –Alternative: Development Kit New Processor Technology –Sharp Processor is in first silicon revision –Processor has small bugs to work around –Alternative: Use different processor and LCD

Risks and Contingency Plan Embedded Linux –Unfamiliar Environment –Alternative: Implement code without operating system GNU Development Environment –Unsupported and not well documented –Alternative: ARM Developer Suite v1.2
