• Manufacturer: Freescale Semiconductor / Motorola

Scope of This Application Note
This application note details the creation of a basic web server for an embedded device. The application
note is a follow-up to AN2624/D: Basic Web Server Development with the CMX-MicroNet TCP/IP Stack .
CMX-MicroNet development with the MC9S12NE64 is very similar to CMX-MicroNet development
MC9S12E128 Ethernet reference design. The discussion will provide an overview of development with
the MC9S12NE64 and the CMX-MicroNet TCP/IP stack. This application note specifically addresses the
following:
This document was created to help familiarize first-time users of the MC9S12NE64 and CMX-MicroNet
TCP/IP stack with the development environment. This understanding will help speed initial MC9S12NE64
and CMX-MicroNet TCP/IP stack application development. To do this, a walk-through of developing a
simple web server is provided. This also includes reviewing some basics of the CMX-MicroNet API and
its Metrowerks
document are described in

embedded device is able to serve the requested information back to the PC. The remote host can also
GET and POST information to the embedded device.
