Project Overview n The ECE Grande is a digital poker game table. n All personal player information is digitally stored n The table will consist of 4 player stations n Central community screen to display community information n Web server to display the current game status on a remote computer

Project-Specific Success Criteria I. An ability to authenticate users using an RFID tag II. An ability to transmit/export the current game state via a TCP/IP connection III. An ability to display each player’s information on individual LCD screen and community information on a central screen.

PSSC – cont. IV. An ability to run a multi-player No. Limit Texas Hold’em game. V. An ability to interface with a distributed network of microcontrollers to control graphic LCDs and receive user input.
