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 CON-

TROLLER

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 Con-

troller.

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 configuration file and click Load. The Evaluation

Board Controller will be reset and the DSP program will be

downloaded. When the download has been completed the
