NetBurner TicTacToe Web Application

Overview

This is a web-based TicTacToe game designed for NetBurner development boards. The application demonstrates embedded web server capabilities, interactive HTML content, and real-time gameplay through a web browser interface.

Features

Core Functionality

Interactive TicTacToe Game: Play against the computer through a web interface
Web Server: Built-in HTTP server running on port 80
LED Manipulation: Control LEDs on the NetBurner development board (URL encoding example)
Request Echo: View web browser requests sent to the server
Auto-Refresh Pages: Meta tag example for automatically reloading web pages

Technical Capabilities

Network Stack: Full TCP/IP implementation with DHCP support
Serial Console: Debug interface with command-line utilities
Diagnostic Tools: Network diagnostics, ARP tables, TCP debugging
Real-time Updates: Dynamic content generation and state management

Game Rules

Player Symbol: X (Cross)
Computer Symbol: O (Circle)
Objective: Get three symbols in a row (horizontal, vertical, or diagonal)
Turn Order: Player moves first by clicking on empty squares
Game State: Preserved in URL parameters between moves

`C`	Show network counters
`E`	Dump Ethernet statistics
`P x.x.x.x`	Ping specified IP address
`W`	Display current system time
`?`	Show help menu

Debug Commands (when _DEBUG is defined)

Command	Description
`T`	Dump TCP debug information
`L`	Setup debug log levels
`U`	Dump OS tasks
`S`	Dump OS stacks
`H`	Show task changes

Technical Implementation

Game Logic

The TicTacToe game uses a bit-encoding system to represent the board state:

Player (X) Positions:**

0x01    0x04    0x10
0x40    0x100   0x400
0x1000  0x4000  0x10000

Computer (O) Positions:**

0x02    0x08    0x20
0x80    0x200   0x800
0x2000  0x8000  0x20000

State Management

Game state is encoded in URL parameters
Each move generates a new URL with updated state
Computer moves are calculated using strategic algorithms
Win/lose conditions are checked after each move

Web Server Integration

Uses NetBurner's built-in HTTP server
Dynamic content generation through function calls
HTML templates with embedded C++ function calls
Real-time state updates without page refresh

Hardware Requirements

NetBurner development board with network capability
Ethernet connection for web access
Serial port for debug console (115200 baud)
LEDs for visual feedback (board-dependent)

Network Configuration

DHCP: Automatically obtains IP address
Web Server: Port 80 (HTTP)
Serial Console: Available for diagnostics
Ping Support: Built-in network connectivity testing

Getting Started

Setup: Connect NetBurner board to network via Ethernet
Power On: Board will automatically start and obtain DHCP address
Access: Open web browser and navigate to board's IP address
Play: Click "Play Tic Tak Toe" to start the game
Debug: Use serial console for network diagnostics
