Page 14: Running The Quickstart Application
Getting Started Now all of the hardware drivers for the LM3S811 Evaluation Board have been installed. These drivers give the debugger access to the JTAG interface and the host PC access to the Virtual COM Port. Running the Quickstart Application The quickstart application is a game in which you navigate a ship through an endless tunnel. -
Page 15: Chapter 3: Hardware Description
LM3S811 Microcontroller Device Overview The heart of the EVB is a Stellaris LM3S811 ARM® Cortex™-M3-based microcontroller. The LM3S811 offers 64 KB flash memory, 50-MHz operation, a 4-channel ADC, and a wide range of peripherals. Refer to the LM3S811 data sheet (order number DS-LM3S811) for complete device details. -
Page 16: Usb Device Controller Functions
An FT2232 device from Future Technology Devices International Ltd manages USB-to-serial conversion. The FT2232 is factory configured by Luminary Micro to implement a JTAG/SWD port (synchronous serial) on channel A and a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous communications links between the host computer and the target device using a single USB cable. -

Stellaris® LM3S811 Evaluation Board Documentation and Software CD) contains complete drivers with source-code for the OLED display. Note that the SSD0303’s I C bus implementation is not 100% compliant with the I C specification. Designers should refer to the SSD0303 datasheet before connecting other I C devices to the bus. -
Page 18: Interfacing To The Evb
Refer to the LM3S811 datasheet for detailed electrical specifications. Using the In-Circuit Debugger Interface The Stellaris LM3S811 Evaluation Kit can operate as an In-Circuit Debugger Interface (ICDI). ICDI acts as a USB to the JTAG/SWD adaptor, allowing debugging of any external target board that uses a Stellaris microcontroller. -

Page 21: Chapter 4: Communications
C H A P T E R 4 Communications This chapter describes available communication for the LM3S811 microcontroller through the Virtual COM Port and the Windows application, HyperTerminal. Using the Virtual COM Port The Virtual COM Port (VCP) is a convenient way for Windows applications to communicate with UART0 on the LM3S811 microcontroller over USB. -
Page 22: Installing The Vcp Device Driver
Communications Installing the VCP Device Driver When the EVB is first connected to a USB port, Windows automatically starts a driver installation wizard. The following steps guide you through the installation wizard. Connect the EVB to an available USB port using the USB cable supplied in the kit. In the Found New Hardware Wizard window, select “No, not this time”... - Page 23 Stellaris® LM3S811 Evaluation Board Insert the Stellaris® LM3S811 Evaluation Kit Documentation and Software CD in the CD-ROM drive. Select “Search removable media (floppy, DR-ROM…)” and click Next. Windows locates the driver on the Documentation and Software CD and start installing the driver.

Page 24: About Hyperterminal
Communications VCP drivers are now installed. Click Finish. You may want to use Device Manager to identify the COM Port assignment. Now that drivers are installed, Windows automatically assign a COM port to the LM3S811 Evaluation Board each time it is connected. About HyperTerminal HyperTerminal is an ASCII terminal emulator that is included with Windows. - Page 25 Stellaris® LM3S811 Evaluation Board Click OK to continue. Select the COM port assigned to the LM3S811 Evaluation Board. In the example below, it is COM7. Click OK. 12/22/06...
- Page 26 Communications Use the Properties dialog box to set the Port Settings. The quickstart application sends data at 115200 baud, 8 data bits, no parity, 1 stop bit, and no flow-control. Click OK. HyperTerminal now starts. When the quickstart game is played, score data is visible in the terminal window.
