The Stellaris Graphics Library accelerates software development by providing a range of

display-related extensions to the standard Peripheral Driver Library. 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, 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.

The display driver provides low-level code for initializing the display controller and a method

for setting pixels. Graphics Library includes a display driver optimized for the RDK-IDM

LCD panel and therefore, users do not need low-level knowledge of LCD-driver operation.

Refer to the Stellaris Graphics Library Reference Manual for full details.

Programming the MDL-IDM and MDL-IDM28

Once an application has been compiled and linked to a binary file, it can be loaded into the

MDL-IDM and MDL-IDM28 by several different methods:

Over Ethernet using the Stellaris Ethernet boot loader

Over the RS232 serial port using the Stellaris serial boot loader

Using the JTAG or SWD port and an In-circuit Debug Interface (ICDI)

All three methods are supported by the LMFlash utility included on the software and

The IDM Reference Design Kit includes an adaptor to convert the fine-pitch, 10-way debug

header to the common 20-pin ARM debug header.
