General Description
The Luminary Micro Stellaris® Intelligent Display Module with 3.5" Landscape Display
(MDL-IDM-L35-L35) offer a complete graphical touch-screen user interface solution for
control, automation, and instrumentation applications. The compact design is based on a
Stellaris® LM3S1958 microcontroller; a highly integrated controller incorporating a 32-bit
ARM® Cortex™-M3 core.
Development of software for the IDM module is simplified by using Luminary Micro’s
comprehensive graphics library and ARM development tools from our tools partners.
First-time users should purchase the RDK-IDM-L35 Reference Design Kit which includes
the touch panel module, a documentation CD, and cables.
See the
RDK-IDM-L35 Quickstart Guide
and
RDK-IDM-L35 User’s Manual
for complete
technical details on using and customizing the Intelligent Display Module.

Power
The IDM-L35 requires 5V DC for operation, which can be applied to one of the three power
supply board connectors (see Table 1). The RDK includes a USB serial cable that provides
power via the serial header connector. In all cases, the power supply must be regulated
within the electrical limits listed in Table 1.

Software Development
The MDL-IDM-L35 ships with a factory-programmed example application. This application
must be replaced with a program specific to the end product. Development requires the use
of a compiler capable of generating code for an ARM® Cortex™-M3 processor. Visit
www.luminarymicro.com
to download evaluation versions of suitable development tools.
The Luminary Micro Graphics Library accelerates software development by providing a
range of display-related extensions to the standard StellarisWare™ Software. The Graphics
Library includes widgets, low-level drawing primitives, and display drivers.
Graphics Library widgets encapsulate the ability to render a GUI element, detect if a
touchscreen press occurred within its bounds, and react to presses. Widgets may be used
in a hierarchical manner to provide groups of associated widgets, such as radio buttons.
Examples of widgets include check boxes, buttons, sliders, and images.
Drawing primitives are elementary geometric items. The Graphics Library includes
primitives such as lines, circles, filled circles, rectangles, and fonts. A selection of pre-built
fonts is included and additional user fonts may be added to the library.
