HOW TO USE THE SOFTWARE
STARTING THE SOFTWARE
To run the program, do the following:
1.
Connect the evaluation board to the
SDP-B
board,
and connect the USB cable from the
SDP-B
board to
the PC.
2.
Power the
SDP-B
and evaluation boards by connecting
6 V to the J3 connector.
3.
Click Start > All Programs > Analog Devices >
AD5592R >.AD5592R Evaluation Software. When
the software connects to the evaluation board, the
message shown in Figure 3 displays.
Figure 3. Connection Message
If the
SDP-B
board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 4). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.

Alternatively, the software can be used without an evaluation
board. The software runs in simulation mode, displaying
expected outputs based on the input data. When the software
runs, the user is first prompted to configure the
AD5592R
input/output pins as shown in Figure 5. The main window of
the
AD5592R
evaluation software then opens, as shown in
Figure 6. The user can click on the block diagram to access the
DAC, ADC, and GPIO functions, as well as other options such
as enabling the internal reference.
Figure 5. Configuration Menu
DAC TAB
The DAC tab gives the user access to the DAC functions. Each
DAC has its own numeric control where a value can be loaded
to the appropriate DAC. Clicking Update DAC Registers loads
the data appropriately as determined by the setting of the LDAC
Mode control.
ADC TAB
The ADC tab allows the user to select ADC channels on which
to perform conversions. The Repeat Sequence checkbox should
be set to take multiple samples. The user can select the number
of samples per channel and the sample frequency. Clicking Take
Samples programs the
AD5592R
for the desired sequence and
takes the appropriate number of samples. The data collected
from the
AD5592R
is split into separate channels and displayed
on the graph as voltage. The user has the option to save the data
to a comma delimited spreadsheet file.
