  2. Objective • As our Capstone project we hope to create an integrated Texas Hold’em poker table. • A poker table with enough intelligence to monitor the game being played and provide information and feedback to the players and dealer. • Our project will incorporate remote recognition of the cards using RFID along with a user interface LCD system.

  3. Implementation • RFID tags attached to cards coupled with a number of RFID pads integrated into the table in the relevant locations. • LCD screen at each player to display chip amount left, current bet, and current bet. • Using the keypad players can call, fold, or raise various amounts.

  4. LCD User Interface • Crystalfontz CFA632 serial LCD 16x2 • 16x2 yellow/green with backlight display • Integrated LED 6-button keypad • RS-232 interface

  5. LCD Specifications • Nominal Supply Voltages: • Supply voltage for driving the LCD module (5.0V) • Supply voltage for backlights (12V) • Supply voltage to run fans (12V) • Typical Current Consumption: • +5 V for logic LCD + microcontroller (13mA) • +12 V for backlight at 100% (45mA) • +12 V for fans (varies)

  6. Powering the LCD • +5 V and +12 V power can be supplied through RS-232 • This allows for a single cable to contain both power and data connections. • It’s default RS-232 pin assignments are all on a single column of pins which allows connection through a .1’’ spacing 5-conductor cable • +12 V fan power must still be run through the PWR connector due to current restriction.

  7. Trossen Robotics RFID Tags • Proximity passive transponder • Ideal for identification applications • Adhesive side allows for tags to be easily attached to cards. • Thin and fits nicely.

  8. Innovations RFID Reader ID-12 • Simple RFID reader module with built in antenna. • Obtain a serial string output containing the unique ID of the tag embedded in the card. • Only has a 100 mm read range so it should not intercept other players’ cards.

  9. Intronix Logic Analyzer Reading exclusive or line feed start of text RFID tag data carriage return end of text

  10. Computer Interface • Provide players with hand history and video feed. • Post-game information allows players to pick up on poker “tells” for future reference. • Length of pauses while contemplating bets • Facial expressions • Provide audience with current hands being played. • Potentially could be broadcasted via internet for others to watch.

  13. System Architecture

  14. MSP430F2470 • Takes care of all connection needs. • 2 UART’S for serial connection for LCD screen/keypad and RFID scanners to local processor. • Also has a I2C for connection with the central processor.
