EVAL-AD7795
INTERFACING TO THE EVALUATION BOARD
Interfacing to the evaluation board is via a standard USB connec-
tor, J1. J1 is used to connect the evaluation board to the USB
port of a PC. A standard USB connector cable is included with
the AD7795 evaluation board to allow the evaluation board to
interface with the USB port of the PC. Because the board is
powered via the USB connector, there is no need for an external
power supply, although one can be connected if preferred, via J3.
Communication between the AD7795 and the PC is via the
USB/SPI interface. The on-board USB controller (U2) controls
this communication.
1. Install the AD7795 evaluation board software, using the
supplied AD7795 evaluation board CD-ROM, before
connecting the board to the PC.
2. When installation of the AD7795 evaluation board soft-
ware is complete, use the supplied USB connector cable to
connect the board to the PC via J1 on the AD7795 evaluation
board and the USB port on the PC. The PC automatically
detects the new USB device and identifies it as the AD779x
Evaluation Board.
3. Follow the onscreen instructions that appear automatically.
During the installation process, if the Hardware Installation
window appears (see Figure 2), click Continue Anyway to
successfully complete the installation of the AD7795 evalua-
tion board.
