EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The AD5064 evaluation kit includes self-installing software on
CD. The software is compatible with Microsoft® Windows® 2000
and Windows XP.
To install the software, take the following steps:
1. Install the software before connecting the evaluation board
to the USB port of the PC. This ensures that the board is
correctly recognized when connected to the PC.
2. Start the Windows operating system and insert the CD. The
installation software should launch automatically. If it does
not, run the setup.exe file directly from the CD.
3. After installation from the CD is complete, power up the
AD5064 evaluation board as described in the Power
Supplies section. Connect the board to the USB port of the
PC using the cable supplied.
4. When the software detects the evaluation board, precede
through the dialog boxes that appear to finalize the
installation.
SOFTWARE OPERATION
From the Analog Devices menu, click Start > All Programs >
Analog Devices > AD5064 > AD5064 Evaluation Software.
For older PCs (prior to Windows® XP), click Start > Programs
> Analog Devices > AD5064 > AD5064 Evaluation Software.
The main window of the AD5064 evaluation software opens, as
shown in Figure 2. The data programmed into the 32-bit input
shift register is displayed. You can select the Control Bits, the
Address Bits, and the Data Bits by clicking the appropriate
option button under each section.
Control Bits
To select a command to program the part, click the drop-down
menu under the Select Control Function section and select the
appropriate option from the menu. For example, to program all
DAC outputs with full scale, select Write to and Update DAC
channel n. Next, click All DACs in the Address Bits section, and
then enter the data in hexadecimal format into the Data section.
To execute, click Write To Part. You must click Write To Part
to execute all writes to the part.
Other commands that the AD5064 evaluation software lets you
program include the power-down DAC bits, the clear code
register bits, and the LDAC register bits. These commands are
performed by clicking the corresponding option button under
the Control Bits section and then clicking Write To Par t. You
can also set the register bits for the required mode of operation.
Consult the AD5064 data sheet for details.
