Stellaris® LM3S9B92 Robotic
Evaluation Board
The Stellaris® Robotic Evaluation Board (EVALBOT)
is a robotic evaluation platform for the Stellaris
LM3S9B92 microcontroller. The board also uses a
range of Texas Instruments’ analog components for
motor drive, power supply, and communications
functions. After a few minutes of assembly, the
EVALBOT’s electronics are ready-to-run.
When roaming, three AA batteries supply power to
the EVALBOT. The EVALBOT automatically selects
USB power when tethered to a PC as a USB device
or when debugging. Test points are provided to all
key EVALBOT signals. Two 20-pin headers enable
future wireless communications using standardized
Texas Instruments’ low-power embedded radio
modules (EM boards). Additional microcontroller
signals are available on break-out pads arranged in
rows adjacent to the microcontroller.
The EVALBOT has factory-installed quickstart
software resident in on-chip Flash memory. For
software debugging and Flash programming, an
integrated In-Circuit Debug Interface (ICDI) requires
only a single USB cable for debug and serial port
functions.
The EVALBOT is available with a Stellaris-specific
version of µC/OS-III: The Real-Time Kernel by Jean
J. Labrosse. This book reveals how a real-time
kernel works using Micrium’s µC/OS-III and the
Stellaris EVALBOT as references. In addition, the
board is also available separately for those who
already have the book.
