SOFTWARE OPERATION
The main window of the EVAL-AD5233SDZ software is
divided into the following sections:
QUICK COMMANDS,
REGISTER ACCESS,
WP
, DIGITAL OUTPUTS, and
MEMORY
. The features of the main window are as follows:
• The QUICK COMMANDS section allows you to send the
AD5233 quick commands directly to the AD5233.
• The REGISTER ACCESS section can be used to update
the RDAC registers by typing a value into a window and
clicking
WRITE. Alternatively, you can send a customized
I
2
C data word by manually switching the scroll bars from 0
to 1 or from 1 to 0, as desired, and then clicking
SEND
DATA
. When WRITE is clicked or a quick command is
executed, a write-read operation is performed, and the
values displayed in this section are updated with the actual
RDAC register values. This function can be used to verify
whether the write operation was completed successfully.
The scroll bars are updated upon each write transfer.
• The
WP
section enables or disables the AD5233
WP
pin.
• The /PR button generates a pulse in the
PR
pin.
• You can pull the digital output pins, O1 and O2, high or
low in the
DIGITAL OPUTPUTS section. Clicking the
STORE button stores the value in memory.
• The MEMORY section displays the data stored in the
memory block. The data can be updated by switching the
scroll bar from
READ to WRITE, updating a particular
window value, clicking
UPDATE ALL or UPDATE
SINGLE
, and selecting the memory location to write.
• Clicking EXIT closes the program but does not reset the part.
