Figure 3 shows all possible electrical connections, including RS232, analog inputs, and
digital I/O. The actual functionality of the peripheral connections is determined by the
application software.

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.
