INSTALLING THE SOFTWARE
The AD5665R evaluation kit includes self-installing software
on CD-ROM. The software is compatible with Microsoft®
Windows® 2000 and Windows XP.
4. The main window of AD5665R evaluation software opens,
as shown in Figure 3. The data programmed into the 24-bit
input shift register is displayed. You can select the command
bits, the address bits, and the data bits by clicking the
appropriate option button under each section.
The software should be installed before connecting the evalua-
tion board to the PC’s USB port. This ensures that the board is
correctly recognized when connected to the PC.
Command Bits
