Abstract

A Monopoly game that outputs to a VGA port in which up to 7 Bluetooth android based devices can view information, roll the dice and execute trades through their Bluetooth devices. The unit itself will output the game board and various animations through VGA while also playing sound through built in speakers.

Design Considerations

We are building a distributed system on the console and Android devices

Had to come up with a simple and lightweight protocol to perform periodic updates of Droids

We are limited to 512kB of memory for game logic and save game data

Bluetooth module could only accept 8 unique connections so this limited us to max of 7 players

Interfacing with Peripherals

Connect to the Bluetooth through UART on pin 52(U1RX) and pin 53(U1TX). Bluetooth operates in slave mode.

Connect with MPEG decoder on pin 66(SCL1 ) and pin 67(SDA1 for I2C1) while the MPEG data is sent on pin 81(Port D). MPEG decoder runs in multimedia mode and provides all signals for DAC.

Connect with CPLD via Port B(15:2) and port D(15:10), Port E(9:0) and Port A(3:2)

Application Code Organization

The overall main function runs as a polling loop

We chose a polling loop because our console goes through the same sequence of operations once the game starts and keeps repeating them until the game ends

The Bluetooth module continuously sends data to the micro as soon as it receives it because it is the sole source of user input.

The microcontroller acts as the central repository of all game data and droids ‘check out’ and ‘commit changes’
