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.

Features

The evaluation kit provides a hands-on mini robotic

platform for learning and using the µC/OS-III

real-time kernel. The evaluation kit includes the
