ECE 477 Final PresentationTeam 3 – Fall 2008
Ashley Callaway, Nikeshia Ebron, Leo Romanovsky, Pat Doherty
Outline
• ECE Grand overview• Block diagram• Design challenges• Individual contributions• Project demonstration• Questions and discussion
ECE Grand Overview
• Functioning electronic poker table with …– RFID based user authentication – Individual player stations with OLED displays and
buttons– Ethernet-based game server– Back end server with player data
Block Diagram
Design Challenges
• SPI network• TTL to CMOS• User authentication
SPI network
• Challenges– Signal integrity– Synchronization
• Resolution– Slow SPI clock– Pull-up resistors on data lines– Structured sequential access
TTL to CMOS
• Challenges– 5 volt TTL interface to 3.3 volt CMOS
• Resolution
User Authentication
• Challenges– Networking three different computers– Multiple Layers of Protocol
• Resolutions
Individual Contributions
• Ashley Callaway• Pat Doherty• Nikeshia Ebron• Leo Romanovsky
Ashley Callaway
• PCB Routing• RFID circuit (TTL to CMOS)• Button assembly
Pat Doherty
• TCP client on microcontroller• UDP server on microcontroller and UDP Client
on PC• RFID Driver• Poker State Machine• Table Construction• PCB Routing and Population
Nikeshia Ebron

Leo Romanovsky
• LCD driver and graphics library• SPI Protocol• TCP Server and MySQL Database on PC• PCB Routing and Population• Website
Project Demonstration• An ability to authenticate users using an RFID tag.• An ability to transmit/export the current game state via a UDP
connection.• An ability to display each player's information on individual
LCD screens and community information on a central LCD screen.
• An ability to run a multi-player No-Limit Texas Hold’em game.• An ability to interface with a distributed network of
microcontrollers to control graphic LCDs and receive user
input.
