CHAPTER 1

Stellaris® LM3S8962 Evaluation Board Overview

The Stellaris® LM3S8962 Evaluation Board is a compact and versatile evaluation platform for the Stellaris LM3S8962 ARM® Cortex™-M3-based microcontrolle r. The evaluation kit design highlights the LM3S8962 microcontroller's integr ated CAN and 10/100 Ethernet controllers.
As well as implementing an embedded web server, the kit functions as a complete controller area network (CAN) by providing two boards each with a Stellaris microcontroller. The main evaluation board (EVB) is the CAN host. A small CAN device board, linked with a ribbon cable, uses a Stellaris LM3S2110 microcontroller. The function of each board is fully configurable in software.
You can use the EVB either as an evaluation platform or as a low-cost in-circuit debug interface (ICDI). In debug interface mode, the on-board microcontroller is bypassed, allowing connection of the debug signals to an external Stellaris microcontroller target. The kit is also compatible with high-performance external JTAG debuggers.
This evaluation kit enables quick evaluation, prototype development, and creation of application-specific designs for Ethernet and CAN networks. The kit also includes extensive source-code examples, allowing you to start building C code applications quickly.
