Description
The Stellaris® LM3S9B92 EVALBOT Robotic Evaluation Board (EVALBOT) supported by StellarisWare® and for use with CodeSourcery Tools, 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´s quickstart application provides out-of-the-box action and can be used along with other included examples as a foundation for seriously fun learning. The examples are based on the included, extensive StellarisWare library and can be modified to meet new challenges using your choice of evaluation versions of the integrated development tools.
