UPDATING THE EVAL-ADPDM3Z
BOARD FIRMWARE
If the EVAL-ADPDM3Z evaluation board firmware is out of
date, the software displays a warning, as shown in Figure 7. If
this warning occurs, click Tools > Firmware Update from the
main window, and click Ok in the dialog box. Follow the
instructions shown in Figure 7 to update the
evaluation board firmware.

CONFIGURING THE EVAL-ADPD2140Z EVALUATION
KIT
To operate the EVAL-ADPD2140Z evaluation board in gesture
detect mode, click View > Gesture Device. Click ADPD
Config to enter the gesture configuration window. Click Load
DCFG, select ADPD1080Z-GST_Gesture.dcfg, and click Open
(see Figure 8).
Figure 8. Loading the Configuration File
By default, this file configures the EVAL-ADPD2140Z evaluation
board to use the LEDX1 light emitting diode (LED) driver,
which is optimized for gesture recognition. After loading the
configuration file, click Power Calculation, which opens a new
window. Press M on the keyboard. In the new window, under
Boost Enable, ensure that the Boost Enable check box is
selected (see Figure 9). This control is automatically selected
upon connecting the EVAL-ADPD2140Z evaluation board and
the EVAL-ADPDM3Z evaluation board to the PC.

STREAMING DATA

Return to the Gesture Device window and click the Play icon to
begin streaming data from the EVAL-ADPD2140Z evaluation
board. Move an object or hand within 30 cm above the EVAL-
ADPD2140Z evaluation board to see the corresponding output
of the device on the graphs. The Y Ratio vs X Ratio graph
shows the calculated x and y positions of the object above the
device (see Figure 10). The Raw Data graph shows the four data
output channels (x , x , y , and y
R L T
reflected light seen by the device, represented in analog-to-digital
converter (ADC) codes. In the Y Ratio vs X Ratio graph, an
offset of 255 codes is applied to all four channels to prevent
division by zero in the calculation of x and y. See the
data sheet for more information.

GESTURE DEVICE

To view the gesture recognition capability, remain in the
Gesture Device window with data streaming turned on.
Move a hand or other reflective object within 30 cm above the
device and swipe in any of the four indicated directions.
Alternatively, the center indicator can be activated by quickly
lowering an object towards the sensor.
