USING THE EVALUATION BOARD TO PROGRAM AN AD9523-1 ON A CUSTOMER BOARD

This guide explains how to use an AD9523-1 evaluation board
to program an AD9523-1 on a customer board via the I
face. It assumes that the user has access to the I
header on the target board, and knows the assigned address of
2
the target I C device.
1. Move Jumpers P13 and P11 to the I2C position.
2
2. Select the desired I C address for the AD9523-1 evaluation
board using Jumper P5 and Jumper P6. Note that the P5 =
P6 = low setting is reserved for SPI mode. Also, this I
address should not conflict with the I
target AD9523-1.
3. Attach a jumper cable from the SDIO_SDA pin of
Header P2 of the evaluation board to the SDA pin on the
target board.
4. Repeat Step 3 for both the SCLK_SCL pin and the GND
pin of the AD9523-1 evaluation board, attaching jumper
cables to the SCL pin and ground pin of the target board,
respectively.
5. On the evaluation software, select Configure Serial Port
from the I/O menu. This window is shown in Figure 27.

6. Click Reset Serial Port and then click Detect Current
Configuration. A dialog box appears and acknowledges
2
the I C mode and address. The evaluation software starts at
2
I C Address 0x060 and stops at the first valid I
that it finds. If the target I
one automatically selected, select the I
target AD9523-1 from the list, and click OK.
7. From the View menu on the menu bar, select Debug
Window. From the Debug window (see Figure 9), click the
I2C Debug button under the I/O Port Status section. The
window shown in Figure 28 appears.

8. Enter the I C address set by Jumper P5 and Jumper P6 on
the AD9523-1 evaluation board, and click Ping. The user
should see a green ACK message as shown in Figure 28.
Repeat this step for the I
If ACK is returned for both addresses, the remote AD9523-1
is ready to be programmed.
If the ping test fails, double-check the cabling between the
2
boards, as well as the I C address of the target AD9523-1.
2
Ensure that the I C address of the AD9523-1 on the eval-
uation board is different from the target AD9523-1. Also,
disconnect the jumper cable, and make sure that I
is working properly on the AD9523-1 evaluation board.
9. Proceed to program the target AD9523-1 with the desired
settings.
a. When finished, click the EEPROM button on the
main window to access the EEPROM window.
b. Click Program EEPROM to write the settings to the
EEPROM.
