MAX86160EVSYS#

Evaluates: MAX86160 MAX86160 Evaluation Kit General Description The MAX86160 evaluation kit (MAX86160EVSYS#) provides a proven design to evaluate the MAX86160 integrated heart-rate monitor sensor module. The EV kit consist of two boards. IFC6410 is the main board and MAX86160 Breakout EV kit is the daughter board that includes the MAX86160. The EV kit is powered using an external 5V/3A power supply to the IFC6410, and +1.8V through an LDO for the sensor and +5.0V for the internal LEDs of the MAX86160. The EV kit comes with a MAX86160EFN+ installed in an 18-pin OLGA package. Features ●● Real-Time Monitoring ●● Data-Logging Capabilities ●● Fully Assembled and Tested ●● Windows® 7, and Windows 8/8.1-Compatible Software Quick Start ●● MAX86160 EV Kit (MAX86160 Breakout EV kit, IFC6410, 5V/3A power adapter and micro-USB cable included) ●● Windows PC Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Visit www.maximintegrated.com/evkit-software to download the most recent version of the EV kit software, SetupPPG_EvKit_max86160_x.x.zip. Save the EV kit software to a temporary folder and uncompress the ZIP file. 2) Open SetupPPG_EvKit_max86160_x.x.msi and follow the instructions from the pop-up windows as shown in Figure 1, Figure 2, and Figure 3. 3) Connect the MAX86160 Breakout EV Kit (J4 and J5) to IFC6410 main board (P1 and P3), as shown in Figure 4. 4) Power up the boards by connecting the 5V/3A power supply adapter to the IFC6410 (J4) and wall socket. 5) Connect the micro-USB cable from the PC to the EV kit board through J3. Ordering Information appears at end of data sheet. 6) Install the ADB drivers for IFC6410. Drivers can be found in the installed folder of Maxim SensorStudio, ..\Maxim Integrated\SensorStudio5\USB_drivers 7) Open SensorStudio5 and verify that the EV kit is connected by observing the status bar at the lowerleft corner of the GUI, as shown in Figure 5. If “Disconnected” is shown, please double-check the board’s power supply, USB connection, and press “Refresh” to try. 8) From the top menu, choose View and then click on “PPG_EvKit”. The MAX86160 PPG evaluation page will then appear, as shown in Figure 6. 9) Pressing the Start Monitoring button with the AGC box checked will start the PPG evaluation. LED current will automatically be adjusted by the driver.

By default, the AGC (auto-gain control) is enabled, in this mode, the LED currents will be dynamically controlled by the software driver to achieve optimal signal. Under this mode, the sample rate is set to 400hz. In order to manually control the settings menu inside the PPG Settings Tab (sample rate, pulse width and LEDs current), AGC must be unchecked. Data Logging The software also provides capability of Data logging. First of all, check the “Log to File” option, and entered the file name by pressing “Browse” (by default under folder \MaximLogs\.). The log file will start saving data once “Start Monitoring” is pressed. PPG Settings Within the PPG Settings tab, both the drive current of IR and Green LED can be adjusted individually. Each LED driver is consisted of four different ranges which can be chosen from IR LED Range/Green LED Range • 0 – 51mA (0.2mA/LSB) • 0 – 102mA (0.4mA/LSB) • 0 – 153mA (0.6mA/LSB) • 0 – 204mA (0.8mA/LSB) After the range is chosen, the LED current can be adjusted from the IR and Green LED current, respectively. In addition to the LED Currents, the PPG Settings Tab also consists of controls to the sample rate and pulse width. For more information about the parameters, please refer to the sensor data sheet. www.maximintegrated.com Evaluates: MAX86160 The Sample Rate drop-down list is adjustable from 10Hz to 3200Hz. The Pulse Width drop-down list is adjustable from 50Hz to 400µsec. The ADC Range drop-down list is adjustable from 4096 to 32768nA. FIFO Settings FIFO Almost Full indicate how many new samples can be written to the FIFO before the interrupt is asserted. For example, if it is set to 15, the interrupt triggers when there is 17 empty space left (15 data samples), and so on. By Checking “FIFO Rolls on Full” options, the FIFO will automatically roll over when it is full. Otherwise, the FIFO will stops accepting new data until it’s read out. To reduce the amount of data throughput, adjacent samples (in each individual channel) can be averaged and decimated on the chip by setting the Sample Averaging. The Sample Averaging drop-down list is adjustable from 1 to 32. RegMapForm The software also provides capability of viewing and changing the Register Settings of the sensor. This feature can be opened by going to the top menu → View → Register Map, as shown in Figure 8. The I2C register can be read back and written to by using the RegMapForm tool (Figure 9). Double-click on the bitfield you would like to change to flip the bit. Then, click Set Reg to update the settings. By using the manual update feature, one can also read and set the sensor register settings easily. Maxim Integrated │  9 MAX86160 Evaluation Kit Evaluates: MAX86160 Figure 8.
