Setup Screen
The Setup Screen is responsible for allowing the user to load
a configuration file for the evaluation board. The configura-
tion file will give the software detailed information about the
evaluation board and part connected to the Evaluation Board
Controller such as number of bits, maximum sampling rate,
power supply requirements etc. The configuration file also
tells the software the name of the DSP program file which it
should download to the Evaluation Board Controller. These
files are supplied by Analog Devices with the evaluation
board. Figure 4 shows the Setup Screen.
SETTING UP THE EVALUATION BOARD
CONTROLLER
The following text describes how the evaluation board
Evaluation Board Controller and software should be set up
for the user to begin using the complete system. The
Evaluation Board Controller and evaluation board should be
connected together (via the 96 way connector). The power
should be applied to the Evaluation Board Controller. At this
stage the red LED should be flashing which indicates that the
Evaluation Board Controller is functional and ready to
receive instructions. The software which should have
been installed should be loaded before the printer port
cable is connected between the Evaluation Board Con-
troller and the PC. This will ensure that the printer port
has been initialized properly. The printer port cable can
then be connected between the PC and the Evaluation
Board Controller.
Running the Software
With the hardware setup the user is now in a position to
use the software to control the Evaluation Board Con-
troller and evaluation board. In the software the user
should select the File menu and click on Setup. This will
display the setup form. A window on the left of the setup
form list all the available configuration files. The con-
figuration files are text based files which contain infor-
mation about the particular evaluation board to be tested.
The information will cover such things as the part name,
number of samples to be taken, default and maximum
sampling frequency power supply settings etc. The
configuration file also contains the name of the DSP
program file which is to be downloaded to the Evaluation
Board Controller. The user should select the relevant
