2. SOFTWARE
The evaluation system comes with software and an
RS-232 cable to link the evaluation board to the
PC. The executable software was developed with
LabWindows/CVI and meant to run under Win-
dows 95
read the readme.txt file for any last minute changes
in the software.
2.1 Installation Procedure
Note: The software is written to run with 640 x 480 res-
olution; however, it will work with 1024 x 768 resolution.
If the user interface seems to be a little small, the user
might consider setting the display settings to 640 x 480.
(640 x 480 was chosen to accommodate a variety of
computers).
2.2 Using the Software
At start-up, the title screen appears first (Figure 1).

1) Turn on the PC, running Windows 95 or 98.
2) Insert the Installation Diskette #1 into the PC.
3) Select the Run option from the Start menu.

the user will be prompted to enter the direc-
tory in which to install the CVI Run-Time
Engine. The Run-Time Engine manages exe-
cutables created with LabWindows/CVI. If
the default directory is acceptable, select OK
and the Run-Time Engine will be installed
there.

software’s title, revision number, copyright date,
etc. Additionally, at the top of the screen is a menu
bar which displays user options. Notice, the menu
bar item Window is initially disabled. This elimi-
nates any conflicts with the mouse or concurrent
use of modems. Before proceeding any further, the
user is prompted to select the serial communication
port.
2.2.1 Selecting the COM Port and Part
To initialize a port, pull down option ComPorts
from the menu bar and select either COM1 or
COM2. Next, the user is prompted to select the ap-
propriate part under the Parts menu. After a port is
initialized and the correct part is selected, it is a
good idea to test the RS-232 link between the PC
and the evaluation board. To do this, pull down the
Setup menu from the menu bar and select the op-
tion TEST RS232. The user is then prompted to set
all the evaluation board’s test switches to the
CLOSED position and then reset the board. Once
this is done, proceed with the test. If the test fails,
check the hardware connection and repeat again.
Otherwise, set the test switches back to the correct
mode as specified in this document, and press reset
again.
If the user wishes to change the speed of communi-
cations between the PC and the microcontroller,
this can be achieved through the BAUD RATE op-
tion.
2.2.2 Setup Window Functions
To make sure that the software and evaluation
board are set up correctly, it is recommended that
the user proceed to the Setup Window and test the
functionality of the part before proceeding (Figure
2). To access the Setup Window, the user can pull
down the Window menu item, or press F1 on the
keyboard. The following describes the various op-
tions and indicators in the Setup Window.
Clock Source: This pull-down menu allows the
user to select the type of clock that will be used
