C H A P T E R 1 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.
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.
– Develop using tools supporting Keil™ RealView® Microcontroller Development Kit (MDK-ARM), IAR Embedded Workbench, Code Sourcery GCC development tools, Code Red Technologies development tools, or Texas Instruments’ Code Composer Studio™ IDE (using a Stellaris evaluation kit or preferred ARM Cortex-M3 debugger) –...
C H A P T E R 2 Hardware Description The IDM-SBC design uses a Stellaris® LM39B92 microcontroller to handle display functions, touch-screen control, Ethernet, USB, CAN, and other peripheral functions. Only a few additional ICs are necessary to complete the design. The entire circuit is built on a compact four-layer printed circuit board.
Hardware Description Functional Description This section describes the IDM-SBC’s hardware design in detail. Microcontroller The Stellaris LM39B92 is an ARM Cortex-M3-based microcontroller with 256-KB flash memory, 80-MHz operation, Ethernet, USB, EPI and a wide range of peripherals. See the LM39B92 data sheet (order number DS-LM39B92) for complete device details.
Stellaris® IDM Single-Board Computer Power and Interface Terminal Block Power, CAN, and I C interfaces are provided through 3.5 mm pluggable terminal blocks. For convenience, the RDK includes the plugs. See the BOM for complete part numbers. Figure 2-4. Pluggable Terminal Blocks I2C is a short-distance intra-device bus that can be used to add capabilities such as an ADC (for analog measurement) or digital inputs and outputs.
Hardware Description Power Supplies The RDK-SBC has a wide input range switching-power supply that creates a 5V 1A rail for board operation. The LM22672 step-down regulator switches at 500KHz with an efficiency of greater than 90%. Board functions require only about 150 mA with the remaining capability available for external interfaces such as USB host.
Stellaris® IDM Single-Board Computer Control Interface The Color LCD module has a built-in controller IC with a multi-mode parallel interface. The EVB uses an 8-bit 8080 type interface with GPIO Port D providing the data bus. Table 2-1. LCD-Related Signals Microcontroller Pin Board Function PE6/ADC1...
Hardware Description S Audio The IDM-SBC has advanced audio capabilities using an I2S-connected Wolfson WM8510 CODEC. The CODEC’s integrated amplifier can directly drive an 8 Ω speaker. Although the CODEC supports a microphone input, pin count limits on the LM3S9B92 result in this feature being unconnected.

Software Development Evaluation versions of these tools may be downloaded from www.ti.com/stellaris. Note that, due to code size restrictions, the evaluation versions of the tools may not build all example programs for the IDM. A full license is necessary to re-build or debug all examples. Instructions on installing and using each of the evaluation tools can be found in the Quickstart guides (for example, Quickstart-Keil, Quickstart-IAR) which are available for download from the evaluation kit section of our web site at www.ti.com/stellaris.

Stellaris® IDM Single-Board Computer To replace the boot loader image or to program example applications into the IDM-SBC using a Stellaris evaluation board to provide JTAG/SWD functionality: 1. Install LM Flash Programmer on a Windows PC. 2. Connect the MDL-ADA2 10-pin to 20-pin adapter (included in the RDK) to the evaluation board ribbon cable.
