CHAPTER 1
Stellaris® LM3S9B92 Evaluation Kit Overview
Luminary Micro's Stellaris® LM3S9B92 Evaluation Board Kit (EK-LM3S9B92) is a low-cost
platform for evaluation of the LM3S9B92 microcontroller. The kit includes two boards, the
EK-LM3S9B92 evaluation board, and the In-Circuit Debug Interface (BD-ICDI) board.
The EK-LM3S9B92 board includes the LM3S9B92 ARM® Cortex™-M3 Microcontroller, a 10/100
Mbit Ethernet port, a full-speed USB-OTG port, connectors for inteface to the BD- ICDI boar d, and
oversized pads for easy connection to the microcontroller GPIO ports.
The BD-ICDI board is a USB full-speed JTAG/SWD debugger board. It includes a USB miniB
connector for connection to a USB PC port, and two shrouded header connectors for connectio n to
the EK-LM3S9B92 board.
Development of software for the EK-LM3S9B92 is simplified by using Luminary Micro's
comprehensive St ellarisW are® peripheral dr iver library and ARM development too ls from our tools
partners. The Stellaris® LM3S9B92 Evaluation Board Kit includes the two boards described, a
documentation CD, and cables. All design files are provided on the EK-LM3S9B92 CD.

Using the EK-LM3S9B92
The recommended steps for using the EK-LM3S9B92 evaluation kit are:
1. Follow the Quickstart guide included in the kit. The Quickstart guide will help get the
EK-LM3S9B92 LC Evaluation Board up and running in minutes.
2. Use your preferred ARM tool-chain and the Luminary Micr o Periph eral Dr iver L ibrary to
develop an application. Software applications are loaded using the BD-ICDI board. See
Chapter 3, “Software Development,” for the programming procedure. The StellarisWare
Peripheral Driver Library Software Reference Manual contains specific information on
software structure and function.
3. Customize and integrate the hardware to suit an end applicatio n. This user's manual is an
important reference for understanding circuit operation and completing hardware modification.
Features
The EK-LM3S9B92 evaluation kit provides the following features:
