1. EKI LM35811 QUICKSTART Stellaris LM3S811 Evaluation Kit for IAR Embedded Workbench The Stellaris LM3S811 Evaluation Kit provides a low cost way to start designing with Stellaris microcontrollers using AR System s Embedded Workbench tools The LM3S811 Evaluation Board EVB can function as either a complete evaluation target or as a debugger interface to any external Stellaris device The included USB cable is all that is needed to provide power and communication to the host PC LM3S811 Evaluation Board Requirements You have a PC with a USB interface running Microsoft Windows 2000 XP or 2003 You have the Stellaris LM3S811 Evaluation Kit Documentation and Software CD CAUTION There is a known electrical issue with the FT2232 device that is used in the on board In Circuit Debug Interface CDI Some USB hubs can cause the device to misbehave with symptoms ranging from failed enumeration to corrupt data transfers If you experience trouble when using the on board ICDI try connecting the USB cable directly to one of the USB ports on your PC or laptop The LM3S811 Evaluation Board is configured for immediate use To power the EVB use the USB cable supplied in the kit Connect the mini b smaller end of the USB cable to the connector labeled USB on the EVB Connect the other end Type A to a free USB port on your host PC The USB is capable of sourcing up to 500 mA for each attached device which is suffic2.
