Luminary Micro's Stellaris Intelligent 3.5-inch landscape display single-board computer reference design kit (RDK-IDM-SBC) features fully integrated 10/100 Ethernet (MAC+PHY), USB Host, and CAN interfaces.

Based on the feature-rich Stellaris LM3S9B92 microcontroller, the intelligent display reference design combines a 3.5-inch QVGA landscape-oriented touch-screen user interface with several serial, digital, and analog connectivity options for easy implementation as a human machine interface (HMI) touch display panel in an embedded control device.

Software development for the RDK-IDM-SBC is simplified by using Luminary Micro's StellarisWare graphics library, USB library, peripheral driver library and ARM development tools from ARM tools partners.

Stellaris IDMs are available with the efficient performance and robust integration of an ARM Cortex-M3 microcontroller, positioning the modules into building access controllers and security systems, intelligent white goods and home appliances, thin clients, and factory automation applications. 

Featuring a 3.5-inch landscape-oriented QVGA 16-bit color LCD resistive touch panel display with white LED backlight, the compact Luminary Micro Stellaris RDK-IDM-SBC design takes full advantage of the vast connectivity features included in the integrated Stellaris LM3S9B92 microcontroller.

Connectivity options include 10/100 Ethernet RJ45 Jack, USB 2.0 Type A connector, CAN through a terminal block interface, and UART and I2C through an expansion header. In addition to the LM3S9B92 microcontroller’s integrated 256K of Flash memory and 96K of SRAM, the Single Board Computer Intelligent Display reference design offers extended board-level memories including 8Mbytes SDRAM connected via the External Peripheral Interface on the LM3S9B92 microcontroller, 1Mbytes of external Serial Flash, USB host connector for external mass storage, and a MicroSD card slot for image, data and code storage.

The design also features I2S Audio CODEC with power amplifier to drive an external 8 Ω speaker. The board is powered by a terminal block connection to a wide input range 12-40Vdc power supply with auxiliary 5V power output. 

The software for the Single-Board Computer Intelligent Display Module includes the royalty-free StellarisWare Library suite, including the StellarisWare Graphics Library, StellarisWare USB Library, and StellarisWare Peripheral Driver Library.

The libraries provide an easy C/C++ applications programming interface that generates graphical elements for the IDM, eases point-to-point connectivity using worldwide serial interface standards, and controls the peripherals found on the LM3S9B92 microcontroller, respectively.  Perhaps even more enticing is that the library is completely stored in factory-programmed ROM on the LM3S9B92 microcontroller.

In addition, the StellarisWare Library suite includes programming support for the IEC 60730 standard, especially useful for manufacturers of household appliances, including washing machines, dryers, refrigerators, freezers, and cookers/stoves. The software support also includes a board support package that provides software drivers for the touch screen, the SD Card interface, the relay output, the sound capability, in-system programming support, and the analog inputs.

The Single-board Computer Intelligent Display Reference Design Kit (RDK-IDM) includes the IDM-SBC board, a CAT5 cable for Ethernet interconnectivity, a USB stick, 8Ω speaker, universal power supply, a debug adaptor that allows connection to the 10-pin JTAG interface on the board with a standard 20-pin ARM JTAG debugger, and CD containing all the module design information, including schematics, BOM, Gerber files, software source code, and documentation.

The RDK-IDM-SBC will be available through Luminary Micro's global sales channel (www.LuminaryMicro.com/sales) and online in late Q2 2009 at a price of $299.
