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

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.
