The ADUX1020-EVAL-SDP is a kit that includes the ADUX1020-EVAL-SMALL and the ADUX1020-EVAL-MCM. The evaluation kit requires the Optical Gesture Evaluation Tool, which can be downloaded from the ADUX1020-EVAL-SDP product page, a graphical user interface (GUI) that provides users with low level and high level configurability, real-time data analysis, and user datagram protocol (UDP) transfer capability so the evaluation board can easily interface to a PC. EVALUATION KIT CONTENTS ADUX1020-EVAL-MCM standard evaluation board ADUX1020-EVAL-SMALL breakout board EVAL-SDP-CB1Z controller board Mini USB cable The USB port of the PC powers the ADUX1020-EVAL-SDP kit. On-board voltage regulators provide voltage supplies for the ADUX1020. ADDITIONAL EQUIPMENT NEEDED PC running Windows 7 operating system ADUX1020-EVALZ-LED daughterboard (optional) The evaluation board schematics indicate signal names for easy identification. For additional information on the functionality of the ADUX1020, refer to the ADUX1020 data sheet.

Unzip the downloaded software folder, run the enclosed ADI_OpticalGesture_ EvaluationTool.exe file, and follow the prompts for installing the Optical Gesture Evaluation Tool software (see Figure 2). For further information, follow the full installation guide included with the Optical Gesture Evaluation Tool software in the downloaded folder. Figure 4. SDP ASIC Connection CONFIGURING THE ADUX1020-EVAL-SDP EVALUATION KIT Before operating the ADUX1020-EVAL-SDP kit, connect any jumper across Header J7 on the ADUX1020-EVAL-MCM. If using the ADUX1020-EVALZ-LED daughterboard, disconnect the jumper from Header J7. 14766-002 To operate the ADUX1020 in gesture detect mode, click File > Load Cfg. Select the 004_ADUX1020_StandardR1.dcfg file and click Open (see Figure 5). Figure 2. Optical Gesture Evaluation Tool Setup 14766-005 To start the Optical Gesture Evaluation Tool application, navigate to the ADI_OpticalGesture_EvaluationTool from the Start menu and click the ADI_OpticalGesture_EvaluationTool icon (see Figure 3). 14766-003 Figure 5. Loading the Configuration File Figure 3. Navigate to Optical Gesture Evaluation Tool from Start Menu At startup, the Optical Gesture Evaluation Tool application automatically checks if the installed Optical Gesture Evaluation Tool software version is up to date. If there is a newer version available, the user is prompted to download the newest version. Next, click View > Off-Chip Analysis and Gesture View to open the Graph XYI tab (see Figure 6). With the evaluation board positioned so there are no objects around it within at least a 20 cm radius, click the Channel Auto Calibration button to calibrate the ADUX1020-EVAL-SDP kit. The Optical Gesture Evaluation Tool then acknowledges if calibration is successful. EVALUATION BOARD USB CONNECTION Ensure the provided EVAL-SDP-CB1Z controller board and ADUX1020-EVAL-MCM connect together and connect to a PC via the USB cable included with the evaluation kit. After the Optical Gesture Evaluation Tool application opens, click File > Connect (see Figure 4) and select SDP ASIC Bridge (Debug). The Optical Gesture Evaluation Tool then acknowledges the ADUX1020-EVAL-SDP kit is connected.

Click the Play button if the device is not already streaming data. 14766-006 Move a hand within 15 cm above the device and swipe in any of the four indicated directions. Alternatively, the center indicator can be activated by quickly lowering a hand towards the sensor (see Figure 8). Figure 6. Running the Channel Auto Calibration STREAMING DATA 14766-008 Press the Play button to begin streaming data from the evaluation board. Move an object or hand within 15 cm above the ADUX1020 to see the corresponding output of the device on the graphs. The Y Ratio vs X Ratio graph shows the calculated x, y position of the object above the device (see Figure 7). The Intensity graph shows the average intensity of reflected light seen by the device, represented in ADC codes. Figure 8.

It functions as a high-power LED driver intended for gesture recognition at distances greater than 15 cm. To use the ADUX1020-EVALZ-LED, attach it to the ADUX1020EVAL-MCM evaluation board as shown in Figure 9. The daughterboard connects to the ADUX1020-EVAL-MCM via five pins, labeled on the daughterboard as GND, GND1, LEDX, 3.3V, and VLED. These pins on the daughterboard plug into five similarly spaced test points on the ADUX1020-EVAL-MCM labeled JL1, JL2, JL3, JL4, and JL5. When connecting the ADUX1020EVALZ-LED, ensure Header J7 on the ADUX1020-EVALMCM is not connected, as shown in Figure 9. The ADUX1020-EVAL-SMALL is a small form-factor breakout board (see Figure 10) for the ADUX1020 that allows easy access to the ADUX1020 pinout via a standard connector cable. Figure 10. ADUX1020-EVAL-SMALL Breakout Board The top view of the connector pinout for the ADUX1020-EVALSMALL is shown in Figure 11. Operation and configuration of the ADUX1020-EVAL-SDP with the ADUX1020-EVALZ-LED daughterboard follows the instructions instructions listed in the Evaluation Board Software Quick Start Procedures section.
