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
documentation CD and available from the
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.
