SOFTWARE OPERATION

The main window of the EVAL-AD5254SDZ software is
divided into the following sections: QUICK COMMANDS,
REGISTER ACCESS, WP , TOLERANCE, and MEMORY. The
features of the main window are as follows:
•
The QUICK COMMANDS section allows you to send the
AD5254 quick commands directly to the AD5254.
•
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 AD5254 WP pin.
•
The TOLERANCE section displays the stored tolerance of
each internal resistor.
•
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.
