CONNECTING MULTIPLE ISL28023 EVALUATION
BOARDS TO A DONGLE
An ISL28023 design can have 55 devices connected on a single
2
I
C bus. The ISL28023 Evaluation Kit allows the user to cascade
up to 54 ISL28023 Evaluation Boards. The dongle uses a slave
address (0x9E) for measuring the current and voltage of the 3.3V.
Figure 11
is a picture of the dongle board connected to multiple
ISL28023 evaluation boards.
Connect the Dongle board to the computer via a USB cable. Start
the ISL28023 evaluation kit demo hardware.
Connect the software to the Dongle by pressing the
Device" button at the bottom right of the software window. If the
connection is successful, the text on the button will be red and
read
"Disconnect
Device". All buttons on the front panel of the
GUI will be enabled. The GUI should look similar to
page
3. When the software connects to the microcontroller, the
software scans for all the acceptable ISL28023 slave addresses
to determine if the device is connected to the dongle.
Once connected, each device can be configured uniquely by
pressing the next button that envelops the main features of the
GUI.
Figure 12
illustrates the button to push.

SYSTEM VIEW
When multiple ISL28023 devices are connected to the dongle
board, a system view screen is available. The system view allows
the user to view all the ISL28023 devices as configured.
To enter the system view, select System under the View drop
down menu. The window in
GUI window will disappear.
The window will size to the number of ISL2803 devices
connected to the dongle.
Pressing the "Start Data Collecting" button will loop through all
sites and measure the configure parameters for each ISL28023
device.
Pressing the "Save Data" button will save data for all sites. See
"SAVING DATA" on page 8
for more detail.
Pressing the "Single Site View" button will restore the main GUI
view.
RESET THE DEVICE
Choosing the Reset selection under the ISL28023 drop down
menu will soft reset the ISL28023 and restore the device to the
default value. A soft reset will perform an auto calibration of the
offset for each of the four channels of the device.
