Product Details
The EVAL-ADPD4200Z-PPG evaluation board provides users with a simple means of evaluating the ADPD4200 photometric front end. The EVAL-ADPD4200Z-PPG evaluation board implements a simple, discrete optical design for vital signs monitoring applications, specifically wrist-based photoplethysmography (PPG).
The EVAL-ADPD4200Z-PPG has three green light emitting diodes (LEDs), one infrared (IR), and one red LED, which all separately driven. A single 7 mm2 photodiode is populated on the board. The photodiode has no optical filter coating. However, a pin for pin alternative device with an IR block filter is available.
The full evaluation system includes the Wavetool Evaluation Software graphical user interface (GUI) that provides users with low level register access and high level system configurability. Raw data streamed to this tool can be displayed in real time with limited latency. Views are provided for both frequency and time domain analysis.
A user datagram protocol (UDP) transfer capability from the Wavetool Evaluation Software (available for download on the EVAL-ADPD4200Z-PPG product page) allows data stream connections and register configurability to external analysis programs, such as LabVIEW® or MATLAB®, in real time.
The EVAL-ADPD4200Z-PPG board is powered by the EVAL-ADPDUCZ microcontroller board (obtained from the EVAL-ADPD4200Z-PPG product page). In addition to the power requirements, serial port interface (SPI) (default) data streams are received from the ADPD4200 by the microcontroller.
A ribbon cable connects these two boards. The microcontroller repackages the data, sending it to a virtual serial port over the USB to the PC, displayed on the Wavetool Evaluation Software.
The EVAL-ADPD4200Z-PPG can also be connected directly to the microcontroller development system of the user, using the SPI for the ADPD4200.
For full details on the ADPD4200, see the ADPD4200 data sheet, which should be consulted in conjunction with the user guide when using the EVAL-ADPD4200Z-PPG evaluation board.
