PACMAN for LandTiger Board

Project Overview

This project implements a Pac-Man game on the LandTiger board, which is powered by an ARM Cortex-M3 processor. It faithfully replicates the original Pac-Man mechanics while integrating specific functionalities required by the LandTiger board, including joystick controls, comprehensive game logic, AI-driven ghosts, sound effects, and CAN bus communication.

Requirements

First part - Basic PacMan Game

• Labyrinth and Pills:

  • Display a maze on the LandTiger screen with exactly 240 Standard Pills.
  • Maintain a central box for potential future use.
  • Generate 6 Power Pills at random positions and at random intervals.

• Game Mechanics:

  • Pac-Man moves continuously in the last chosen direction until it encounters a wall or receives new input.

  • The joystick allows direction changes (left, right, up, down).

  • The speed should be balanced for a smooth and enjoyable gameplay experience.

  • Teleportation: When Pac-Man reaches a teleportation point, he reappears on the opposite side of the maze.

  • Scoring system:

    • Standard Pills: +10 points
    • Power Pills: +50 points
    • Every 1000 points, Pac-Man earns an extra life.

  • Pause Feature: Pressing INT0 toggles between pausing and resuming the game.

  • Countdown Timer: Starts at 60 seconds; the game ends when it reaches 0.

  • Win Condition: Pac-Man wins by eating all the pills.

  • Lose Condition: The game is lost if the countdown reaches zero.

Second part - Advanced Features

• AI-Controlled Ghost (Blinky):

  • Blinky Behavior: Actively chases Pac-Man.

  • Movement Strategies:

    • Chase Mode: Blinky follows Pac-Man using an AI algorithm (e.g., A* pathfinding)

    • Frightened Mode: Activated when Pac-Man eats a Power Pill:

      • Blinky turns blue for 10 seconds and runs away.
      • If Pac-Man eats Blinky, he gains +100 points.
      • Blinky respawns in the central box after 3 seconds.

• Audio Integration:

  • Configure the speaker to play sound effects and background music

• CAN Bus Communication:

  • Transmit score, remaining lives, and countdown timer via the CAN bus.
  • Configure CAN1 (sender) and CAN2 (receiver) for external loopback mode.

Development Environment

• Platform: LandTiger Board with ARM Cortex-M3
• IDE: Keil µVision
• Compilation Target: SW_Debug (for emulator) / Physical Board (for advanced features)

How to Build and Run

• Compile the code in Keil µVision.
• Flash the program onto the LandTiger board.
• Use the joystick to control Pac-Man.
• Monitor the game status on the display and CAN bus.
• Listen to sound effects from the speaker.
