2. Outline Project overview Project-specific success criteria Block diagram Component selection rationale Packaging design Schematic and theory of operation PCB layout Software design/development status Project completion timeline Questions / discussion

3. Project Overview A voice controlled chess game that can display possible moves for the chess piece selected by the player RGB LED matrix panel to display the chess board and the current state of the game OLED to display other game statistics Separate microcontrollers and a processor dedicated to the each of the game logic, display, and voice recognition

4. Project Specific Success Criteria 1.An ability to correctly output the current state of the game. 2.An ability to select and move a piece on the chess board with voice commands. 3.An ability to show players' possible moves for a piece they have selected. 4.An ability to keep track of in-game statistics such as time and pieces lost during the play. 5.An ability to tell the player when a move is illegal, or when they are in check/checkmate state.

6. Component Selection Rationale Game Logic Micro - PIC24FJ128GA006 128 kB of flash memory for chess logic 2 SPI channels for LCD Display 1 I 2 C for transmitting data to display control micro 1 UART channels for input from the voice recognition micro 53 Max I/O pins 8 MHz of operating frequency

7. Voice Recognition Micro – dsPIC33FJ128GP202 Speech Recognition Capability 128 kB of flash memory 1 UART channels to talk to the game logic micro High-Speed ADC Module 21 Max I/O pins 7.37 MHz of operating frequency

8. Display Logic Micro – PIC24EP512GU810 512 kB of flash memory 12 PWM channels with resolution of 50 MHz for fast display refreshing 83 Max I/O pins 7.37 MHz of operating frequency

9. Voice Band CODEC with Mic – Si3000 ATD conversion Amplifying capability Good documentation

10. 16x32 RGB LED Matrix Panel Display Limited options More convenient than having each square of the chess board as an individual matrix Reasonable cost as compared to others Good documentation

11. OLED Display – NDH-0216KZW-AB5 Wide viewing angle and easy to read Since it was still within our budget, we moved forward with it

12. Packaging Design 210x412x30mm 8.25x16.25x1in 2 OLED Panels 2 Keypads 2 Microphones 2 Push Buttons 1 Power Button 2 RGB LED Matrix (16x32)

41. Software Development Status Basic “Heart-Beat” check programs Interfaced PIC24FJ128GA010 with the LCD display using a simple program Game Logic implementation in C in progress: basic input output, check if the move played is legal, display possible moves for the piece selected by the player, etc.

42. Project Completion Timeline Mar 3 - Mar 8 Finish and submit the PCB Layout Mar 18 - Mar 24 Complete Game logic and start interfacing it with the micro. Continue working on Voice Recognition and display logic. Start testing the PCB. Mar 25 - Mar 31 Continue interfacing game logic with the micro. Begin interfacing voice recognition and display logic with the micro. Start populating the PCB with the micros and other components. Apr 1- Apr 7 Finish individual components Apr 8 - Apr 13 Connect individual components

43. Project Completion Timeline Apr 14 – Apr 20 Troubleshoot. Start Packaging. Start documentation: poster, final report, lab notebook, peer review Apr 21- Apr 28 Test and Debug. Finish Packaging. Finish documentation: poster, final report, lab notebook, peer review May 11 Graduate? Maybe???? Apr 29 – May 1 Test. Debug. Test. Complete.
