LOAD/SAVE REGISTERS CONFIGURATION
The software program allows saving a specific register configura-
tion and loading it back into the USER REGISTERS section.
The Save Config button, when clicked, opens the file utility
where you can specify the directory and file name to save. The
default extension is *.dat. Maintaining this convention is recom-
mended. If the file does not exist, it is created; if the file already
exists, it is overwritten.
The Load Config button, when clicked, opens the file utility
where you can specify the directory and file name to load.
The default extension is *.dat. If you choose to cancel the
operation, an error message appears (see Figure 21). Click
Continue to abort the operation.
ADDITIONAL COMMANDS
The INFO button, when clicked, provides information regarding
the software revision number and other release notes.
The EXIT button, when clicked, stops the program, leaving the
window active and open. To terminate the program completely,
click the close button (X) on the upper right corner of the applica-
tion window.
On-line help is available by selecting Show Context Help from the
Help menu, or by pressing CTRL + H. Moving the pointer over a
control option or indicator displays information related to it in the
context help window.

WARNING
Upon starting the ADP5020 application, a dedicated firmware
is loaded into the adapter board processor (Cypress IC). This
firmware is needed for the operation of the USB adapter and
communication with the ADP5020 daughterboard. If the evalua-
tion board is not connected through the USB cable, an error
message, as indicated in Figure 15, appears on the screen. This
indicates that the firmware was not loaded into the adapter
board. If this happens, check the USB connection and ensure
that Jumper LK10 is in the USB position. The firmware is loaded
in volatile memory inside the Cypress processor; therefore, if
power is removed or the USB cable is disconnected, the firmware
is lost. If this happens, close the application, connect the adapter
board, and then launch the ADP5020 application again to
reload the firmware.
It is recommended to always stop the program (click the EXIT
button) before removing the USB cable.
HISTORY
Whenever a command is issued (both read and write), it is
recorded in the History dialog box shown in Figure 22.
To display the History dialog box, click the History button on
the bottom right corner of the software GUI (see Figure 14). To
clear the history, click Clear History.
You can copy and paste the history into a file for future
evaluation purposes.
