The EVAL-ADPD144RIZ-SF provides users with a means of evaluating the ADPD144RI, a complete photometric system designed to measure optical signals from ambient light and from synchronous, reflected light emitting diode (LED) pulses. The evaluation system includes the Applications Wavetool graphical user interface (GUI), which provides users with low level and high level configurability; real-time frequency and time domain analysis; and a user datagram protocol (UDP) transfer capability so that the evaluation board can easily connect to the user development system.
The EVAL-ADPD144RIZ-SF is a multiboard evaluation kit consisting of an adapter board and a sensor board connected by a 3 foot cable. The adapter board connects to the EVALADPDUCZ microcontroller board through a ribbon cable.
The evaluation board is optimized for ear-based photoplethysmography (PPG) measurements.
For additional information on the functionality of the ADPD144RI, see the ADPD144RI data sheet in conjunction with this user guide when using the EVAL-ADPD144RIZ-SF.

GETTING STARTED
INSTALLING THE APPLICATIONS WAVETOOL
Download the Applications Wavetool software package from the EVAL-ADPD144RIZ-SF product page. Unzip the folder and run the Applications Wavetool executable file. Follow the prompts, beginning with the Applications Wavetool Setup window shown in Figure 2 for software installation. The Applications Wavetool is periodically updated to add features and improve performance. It is recommended that customers use the latest revision to take advantage of new features and performance.
UG-1272
CHECKING THE USB SERIAL CONNECTION IN WINDOWS
Ensure that the communications port (COM port) driver is installed correctly. To verify proper installation, go to Control Panel > All Control Panel Items > System > Device Manager, as shown in Figure 3. In this case, the proper COM port choice is USB Serial Port (COM16). The EVAL-ADPDUCZ microcontroller board uses an FT232 USB, universal asynchronous receiver transmitter (UART) IC. If the USB driver does not install properly, refer to the FTDI driver installation guide that corresponds with the operating system in use.
16737-005
Figure 2. Applications Wavetool Setup
CONNECTING THE EVAL-ADPDUCZ MICROCONTROLLER BOARD AND THE EVALADPD144RIZ-SF
Connect the USB cable to the EVAL-ADPDUCZ and the ribbon cable to the EVAL-ADPD144RIZ-SF. Switch the power switch to the ON position.
When the power switch is in the ON position, the LED near the power switch illuminates, indicating that the EVAL-ADPDUCZ microcontroller board is on. When the USB cable is connected to the EVAL-ADPDUCZ, the second LED near the power switch illuminates, indicating that the on-board battery is charging.

UPDATING THE EVAL-ADPDDUCZ FIRMWARE
The EVAL-ADPDUCZ microcontroller board may have an older version of the firmware installed during manufacturing. If the user receives the message shown in Figure 4 when trying to connect to the Applications Wavetool, the EVAL-ADPDUCZ must be updated.

ACQUIRING DATA
RUNNING THE APPLICATIONS WAVETOOL
To start the Applications Wavetool, navigate to the Start menu > Analog Devices > ApplicationsWaveTool and click ApplicationsWavetool.
USB UART CONNECTION
To establish the connection, follow the menu path Connection > Connect > UART Bridge.
EVAL-ADPD144RIZ-SF User Guide
SELECTING THE PROPER VIEW
The ADPD144RI is intended for nonwrist-based PPG measurements. Click the ADPD Device data view (see Figure 6) to open a window that allows the user to run the ADPD144RI device and collect data (see Figure 7).

LOAD CONFIGURATION
In the upper right corner of the data view window, click ADPD Config to open the ADPD Config window shown in Figure 7. Click Load DCFG to choose a configuration file. For PPG measurements, choose the 144RI_earbud.dcfg configuration file.

OPTIMIZING AND RUNNING THE ADPD144RI
After the configuration file is loaded, the settings can be further optimized using the ADPD Config window shown in Figure 7. Typically, the device is set up under a certain set of conditions, such as measuring the response from a fixed reflector or measuring a PPG signal from the ear (see Figure 8). Settings can be optimized for any set of conditions by manipulating LED drive currents, transimpedance amplifier (TIA) gain, and
UG-1272
analog front end (AFE) timing. Another option is to use different operating modes that can be more optimal for a specific set of conditions, such as using float mode for a low current transfer ratio (CTR). For information on optimization of the ADPD144RI, refer to the ADPD144RI data sheet. For functional descriptions of the Applications Wavetool, refer to the Applications Wavetool user guide provided in the software package download.
