You have just installed the drivers for “Stellaris Evaluation Board A.” The USB device built
into the EVB is a composite USB device. After you click Finish, Windows automatically
installs a driver for the “Stellaris Evaluation Board B” part of the composite USB device.
Follow the same instructions as above to install the drivers for this device.
The Found New Hardware Wizard appears one last time. This is to install the drivers for the
“Stellaris Virtual COM Port.” Again, follow the same instructions to install the drivers for this
device.
Now all of the FTDI drivers for the LM3S9B90 Evaluation Board have been installed. These
drivers give the debugger access to the JTAG/SWD interface and the host PC access to the
Virtual COM Port.
With the drivers installed, Windows will automatically detect any new Stellaris boards that
you attach, and install the drivers for you.
Quickstart Application
The LM3S9B90 Evaluation Board comes preprogrammed with a quickstart application. Once
you have powered the board, this application runs automatically. The quickstart application is
a game that consists of a Z-machine interpreter running a Z-code version of the classic
Colossal Cave Adventure game originally created by William Crowther. The Ethernet
interface provides a telnet server and the USB interface provides a CDC serial port. Either
interface can be used to play the game, though not at the same time.
The LED on the evaluation board will be turned on when the game is being played; further
connections will be refused since only one instance of the game can be played at a time. The
push button on the evaluation board will restart the game from the beginning; this is
equivalent to typing ``restart'' followed by ``yes'' in the game itself.
The virtual COM port provided by the ICDI board (which is connected to UART0 on the
evaluation board) provides a simple status display. The most important piece of information
provided is the IP address of the Ethernet interface.
The game is played by typing simple English sentences in order to direct the actions of the
protagonist, with abbreviations being allowed. For example, ``go west'', ``west'', and ``w'' all
perform the same action.
Three display modes are available; ``verbose'' (which displays the full description every time
a location is visited), ``brief'' (which displays the full description the first time a location is
visited and only the name every other time), and ``superbrief'' (which only displays the name).
The default display mode is ``brief'', and ``look'' can be used to get the full description at any
time (regardless of the display mode).
