DEMONSTRATION OVERVIEW
Chapter 4. HTTP Web Server Demonstration
This chapter describes a sample program that demonstrates Web-based monitoring
and control of an embedded application operating with the CMX-MicroNet TCP/IP
Stack configured for Hyper Text Transfer Protocol (HTTP) Web Server protocol.
Information in this chapter includes:
• Demonstration Overview
• Demonstration Setup
• Configuring your Laptop or Desktop PC
• HTTP Web Server Demonstration
• Debugging TIPS
• Troubleshooting
• Using HTTP Web Server in Your Application
This demonstration program runs on the dsPIC30F6014 using the CMX-MicroNet
TCP/IP Stack configured for HTTP Web Server protocol to support remote monitoring
and control of the application over an Ethernet connection.
The CMX-MicroNet TCP/IP Stack is designed for optimized use of Flash and RAM
Memory on dsPIC30F devices. This software runs directly on the processor with no
gateways or PCs required. The stack can be run in stand-alone mode or work in
conjunction with an RTOS. This demonstration uses approximately 4.2K instructions in
Flash and 300 bytes in RAM, not including the HTML, java applets and.jpg and.gif
images.
In this demonstration the dsPIC “serves-up” HTML pages to a browser and implements
two basic HTML form methods: GET and POST. The GET and POST methods are
demonstrated in the form of requests from and updates to the HTML page displayed
on a browser. These functions enable you to monitor and change functions on the
dsPICDEM.net board.
The GET method retrieves information from the potentiometers, temperature sensor
and switches to illustrate monitoring functionality. The POST method uploads
information to the LCD and LEDs on the board to illustrate control and updating
functionality. For this demonstration the HTML page served-up by the dsPIC device is
stored in the Flash Program Memory. Alternatively, the dsPICDEM.net board provides
a 24LC515 Serial I
pages.
