Stellaris® Intelligent Display Module Single-Board
Computer RDK Overview
The Stellaris® Intelligent Display Module Single-Board Computer (RDK-IDM-SBC) is a reference
design for a complete QVGA touch-screen user interface for control, automation, and
instrumentation applications. The design features the powerful Tempest-class LM3S9B92
microcontroller. The IDM-SBC offers USB, Ethernet, CAN, 8 MB of SDRAM, 1 MB of serial Flash,
integrated 256 KB flash, and 96 KB SRAM, and provides simplified software development for the
RDK using The Stellaris comprehensive graphics library and ARM development tools from ARM
tools partners. The 8 MB of SDRAM is connected to the LM3S9B92 microcontroller using the
External Peripheral Interface (EPI) bus available as a feature on Tempest-class devices. The
efficient performance and robust integration of an ARM® Cortex™-M3 microcontroller, positions
the IDM-SBC for use in building access controllers and security systems, intelligent white goods
and home appliances, thin clients, and factory automation applications.
This user's manual provides comprehensive information on the reference design hardware and
software.

Kit Contents
The RDK-IDM-SBC reference design kit contains everything needed to develop and run a range of
applications using Stellaris microcontrollers:
IDM-SBC board
8ΩSpeaker
Retractable ethernet cable
USB flash memory stick
microSD card
Power supply adaptor cable
2-position and 6-position terminal blocks
24 V wall power supply with international plug-set
MDL-ADA2 10-pin to 20-pin JTAG adapter module
Reference Design Kit CD with tools, complete documentation, and source code including:
–Quickstart Guide
–User’s Manual
–Software Reference Manual
–Board Data Sheet
–BOM
–Schematics
–Gerber files
The source code can be modified and compiled using any of the following tools:
Keil™ RealView® Microcontroller Development Kit (MDK-ARM)
IAR Embedded Workbench
Code Sourcery GCC development tools
Code Red Technologies development tools
Texas Instruments’ Code Composer Studio™ IDE
Using the RDK
The recommended steps for using the RDK are:
Follow the Quickstart guide included in the kit. The Quickstart guide will help get the
display module up and running in minutes.
Use your preferred ARM tool-chain and the Stellaris Graphics library to develop
touch-panel, USB, and Ethernet applications. Software applications can be loaded into IDM
flash memory using either the Ethernet boot loader or a JTAG/SWD debug interface. See
Chapter 3, “Software Development,” for the programming procedure. The Stellaris Graphics
Library Software Reference Manual and the Stellaris Peripheral Driver Library Software
Reference Manual each contain specific information on software structure and function.
Customize and integrate the hardware to suit an end application. This user's manual is an
important reference for understand circuit operation and completing hardware modification.
