MCF51CN128—Lab Tutorials 1 & 2

Security System,

Freescale MQX™ RTOS

for MCF51CN128

Introduction

This lab will guide you through the general

use of the Freescale MQX™ operating

system under the CodeWarrior™ integrated

development environment and will

familiarize you with the general compile

and download process. This lab will

simulate an Ethernet-enabled home security

system that is accessed over telnet.
