SOFTWARE INSTALLATION PROCEDURE
To use the
USB-SDP-CABLEZ
for SPI communication, a
LabVIEW executable is available. The LabVIEW executable
requires that the
USB-SDP-CABLEZ
drivers be installed, and
that a LabVIEW runtime engine compatible with LabVIEW 2011
is available.
1.
Install
SDPdrivers.exe
(available from Analog Devices).
2.
Install LabVIEW Runtime Engine 2011 or later (available
from National Instruments).
3.
Double-click A
DuM4138_eval_progam_01.exe
to run.
STOP
Click
STOP
to halt the LabVIEW program. Alternate methods
of stopping the program are to close the window, or force quit
the program. All of these options set the CS pin to an unknown
state, so it is recommended to remove the
USB-SDP-CABLEZ
connection from the evaluation board before shutting the
program down.
Read Addr:00
Click
Read Addr:00
to see what the
ADuM4138
has in the
EEPROM at Address 00 (user trim bits). Clicking
Read
Addr:00
sends two read commands. This is because of the way
that the SPI setup operates. The second read command pushes
the data loaded by the first read command to the MISO pin.
The result of the second read appears in the
Addr:00 Output
field.
Read Addr:01
Click
Read Addr:01
to see what the
ADuM4138
has in the
EEPROM at Address 01 (configuration trim bits). Clicking
Read Addr:01
sends two read commands. This is because of the
way that the SPI setup operates. The second read command
pushes the data loaded by the first read command to the MISO
pin. The result of the second read appears in the
Addr:01
Output
field.
Read Addr:10
Click
Read Addr:10
to see what the
ADuM4138
has in the
EEPROM at Address 10 (control bits). Clicking
Read Addr:10
sends two read commands. This is because of the way that the
SPI setup operates. The second read command pushes the data
loaded by the first read command to the MISO pin. The result
of the second read appears in the
Addr:10 Output
field.
Write/Read Addr:00
Click
Write/Read Addr:00
to perform a single write comprised
of the bit pattern set by the user in the
OFFSET_2
field, the
GAIN_2
field, the
OFFSET_1
field, and the
GAIN_1
field.
After the single write, a single read is performed, allowing the
user to verify that the sequence is sent. The result of this read is
