Simple HTML

NetBurner Simple HTML Example

Overview

The Simple HTML Example is a basic demonstration of the NetBurner web server implementation and serves as an excellent starting point for custom embedded web applications. This example creates a minimal web server that displays a "Hello World" type message on the device's index page.

Application Description

This embedded web application initializes a NetBurner device to serve HTML content over HTTP. The application demonstrates the fundamental components needed to create a web-enabled embedded system using the NetBurner Real-Time Operating System (NBRTOS).

Key Features

• Web Server: Runs an HTTP server on the default port 80
• Network Stack: Initializes the complete network stack for web connectivity
• System Diagnostics: Includes optional system diagnostic capabilities
• Real-Time Operation: Built on NBRTOS for reliable real-time performance
• Simple Interface: Displays a basic HTML page with NetBurner branding

File Structure

/
    main.cpp         - Main application entry point
    index.html       - Default web page served by the application
    style.css        - CSS styling for the web interface

How It Works

Application Flow

1. Initialization: The UserMain() function initializes the network stack
2. Diagnostics: Enables system diagnostics for debugging (should be removed in production)
3. Web Server: Starts the HTTP server on port 80
4. Network Wait: Waits up to 5 seconds for active network connection
5. Status Display: Prints application name and NNDK revision to console
6. Main Loop: Enters infinite loop with 1-second delays

Web Content

The application serves a simple HTML page (index.html) that includes:

• NetBurner logo and branding
• Basic styling via CSS
• "Thank you for NetBurning!" message
• Link to NetBurner website

Technical Details

Dependencies

• NBRTOS: NetBurner Real-Time Operating System
• Network Stack: Built-in TCP/IP stack
• HTTP Server: Integrated web server functionality

System Requirements

• NetBurner compatible hardware
• Network connectivity (Ethernet or WiFi depending on platform)
• NNDK (NetBurner Network Development Kit)

Usage

1. Compile: Build the application using the NetBurner development environment
2. Deploy: Load the application onto your NetBurner device
3. Connect: Ensure the device is connected to your network
4. Access: Open a web browser and navigate to the device's IP address
5. View: The simple HTML page will be displayed

Development Notes

Production Considerations

• Remove EnableSystemDiagnostics() call for production deployments
• Customize the HTML content in index.html for your specific application
• Modify CSS styling in style.css to match your branding
• Add additional web pages and functionality as needed

Customization

This example serves as a foundation for more complex web applications. You can:

• Add dynamic content generation
• Implement form handling
• Create RESTful APIs
• Add authentication and security features
• Integrate with sensors and other hardware

Console Output

When running, the application displays:
