Pac-Man for LandTiger Board

Project Overview

This project implements a Pac-Man game on the LandTiger development board, featuring an ARM Cortex-M3 processor. The implementation follows the original Pac-Man game mechanics while incorporating specific requirements for the LandTiger board, including joystick controls, game logic, AI-controlled ghosts, sound effects, and CAN bus communication.

Requirements

Extrapoint 1 - Basic Pac-Man Game

1. Labyrinth and Pills:

   • Display a maze on the LandTiger screen with exactly 240 Standard Pills.
   • Maintain a central box, which may be used later.
   • Generate 6 Power Pills in random positions at random times.

2. Game Mechanics:

   • Pac-Man moves continuously in the last chosen direction until a wall or new input.
   • Joystick controls allow direction changes (left, right, up, down).
   • Speed should be playable and user-friendly.
   • Teleportation: When Pac-Man reaches a teleport point, he reappears on the opposite side.
   • Scoring System:
     • Standard Pills: +10 points
     • Power Pills: +50 points
     • Every 1000 points, Pac-Man earns an extra life.
   • Pause Feature: Pressing INT0 pauses and resumes the game.
   • Countdown Timer: Starts from 60 seconds; game ends when it reaches 0.
   • Win Condition: Pac-Man eats all the pills.
   • Lose Condition: Countdown reaches zero.

Extrapoint 2 - Advanced Features

1. AI-Controlled Ghost (Blinky)

   • Blinky actively chases Pac-Man.
   • Two movement strategies:
     • Chase Mode: Blinky follows Pac-Man using an AI algorithm (e.g., A* pathfinding).
     • Frightened Mode: Activates when Pac-Man eats a Power Pill:
       • Blinky turns blue for 10 seconds and runs away.
       • If Pac-Man eats him, +100 points.
       • Blinky respawns in the central box after 3 seconds.

2. Audio Integration

   • Configure the speaker to play sound effects and background music.

3. CAN Bus Communication

   • Send score, remaining lives, and countdown timer through 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

1. Compile the code in Keil µVision.
2. Flash the program into the LandTiger board.
3. Use the joystick to control Pac-Man.
4. Monitor game status on the display and CAN bus.
5. Listen to sound effects from the speaker.
