Evaluates: MAX30207 MAX30207 Evaluation Kit General Description The MAX30207 evaluation (EV) system provides a single platform to evaluate the MAX30207, a +/-0.1°C accurate temperature sensor. The EV system consists of two boards connected through headers, a MAX32630FTHR microcontroller board, and the MAX30207_INTERFACE_ EVKIT board. The EV system also includes a MAX30207_ SENSOR_FLEX_EVKIT flex module that holds the MAX30207 IC. The MAX32630FTHR contains the firmware necessary to use the PC GUI program and provides power to the MAX30207 interface board. The MAX30207 interface board ships with jumpers preinstalled to allow quick evaluation of the MAX30207.

Once the driver installation is complete, a Windows message appears near the system icon menu, indicating the hardware is ready to use. Do not attempt to run the GUI prior to this message. To do so, close the application and restart it once the driver installation is complete. On some versions of Windows, administrator privileges are required to install the USB device. Detailed Description of Software Software Startup If the EV system is connected when the software is opened, the software first initializes the hardware to communicate. The software then reads the device registers and updates all the associated control fields displayed on the GUI. If the EV system is not connected on start-up, the GUI starts and displays no devices in the Devices section of the GUI and no temperature reading in the Selected Device section. The status bar at the bottom of the GUI states Not Connected. 6) Once the device drivers are installed, download the EV kit software from www.maximintegrated.com/ evkit-software (MAX30207EVKitSoftwareInstall.ZIP) and extract it to a temporary folder. 7) Open the extracted ZIP folder and double-click the .EXE file to run the installer. If a message box stating ‘The publisher could not be verified. Are you sure you want to run this software?’ appears, select Yes. Once an EV system is connected, the GUI automatically sets the device registers and begins taking temperature measurements. 8) When the installer GUI appears, click Next. Select the installation paths and if a shortcut should be created on the desktop. When prompted, press Install. Once complete, click Close. 9) If a shortcut is created, double-click on the created shortcut to start the GUI. Alternatively, go to Start | All Programs. Find the MAX30207EVKitTool folder and click on the MAX30207EVKitTool.EXE file inside the folder. The ToolStrip menu bar (Figure 1) is located at the top of the GUI window. This bar comprises the File, Device, Logging, and Help menus, the functions of which are detailed in the following sections. 10) When the GUI appears, the text in the right field of the bottom status bar displays Connected. If the GUI displays Not Connected, ensure the flex PCB is properly connected and power-cycle the MAX30207 EV Kit. ToolStrip Menu Bar File Menu The File menu contains the option to exit the GUI program. Device Menu The Device menu connects or disconnects an EV system to the GUI. If a board is disconnected while the GUI is open, the GUI displays Hardware Not Connected in the lower right corner. If the device is then plugged back in, navigate to the Device menu and select Connect. If successful, the bottom right corner of the GUI reads Device Connected. Figure 1.

MicroSD logging operates the EV kit without a connection to a host PC or power supply. First, insert a microSD card into the connector at the bottom of the MAX32630FTHR. For logging under battery powered, after selecting the logging interval and writing the selection to the microSD card (Figure 3), connect a 3.7V lithium-ion battery with a JST PH connector to the MAX32630FTHR and then disconnect the board from the host PC. Refer to the MAX32630FTHR documentation for details on connecting a Li+ battery. Press SW2 on the MAX32630FTHR board to start (LED D1 blinking red) saving measurements to the SD card. Pressing SW2 again (LED D1 blinking blue) stops measurements. To transfer the logged data from the MicroSD card to a file on a PC, reconnect the MAX30207 EV kit to the PC and select microSD card logging from the Logging menu. Select the ‘Save to File’ option and a prompt appears to name the log file (Figure 2). For subsequent logging sessions, press ‘Clear Log’ on the ‘Setup MicroSD Logging’ screen to prevent multiple data sets being recorded to the same log file. Data logging can also be accomplished by using ‘Save’ in the ‘Plot’ tab. Help Menu The Help menu contains information to aid with any problems in the use of the GUI. About displays the GUI splash screen indicating the GUI version being used. Figure 2.

General Tab The General Tab (Figure 4) displays a general overview of the MAX30207. The tab provides a list of devices connected, temperature data for a selected device, as well as controls for select registers. Plot Tab The Plot tab plots the measured data for a single MAX30207 temperature sensor (device), or a list of devic- Evaluates: MAX30207 es connected by selecting the device using the check box in the plot column. Use ‘Plot Duration’ and ‘Sample Temperature Every’ to set the plot duration and sample rate, then click ‘Start’ (Figure 5). The other function of the plot tab is to log the temperature data that provides a way to export each data sample being measured by the device. After the plot is started, click ‘Save’ to save the plotted data to a file. A prompt then appears to choose a name for the comma-separated value (CSV) log file, as well as the location to save the generated file. Figure 6 shows the log file format. Click ‘Reset’ to clean the buffer and prevent multiple data sets being recorded to the same log file. Figure 4.

Log File Format www.maximintegrated.com Maxim Integrated │  6 MAX30207 Evaluation Kit Register Map Tab The Registers Map tab (Figure 7) provides more direct access to the internal registers of the MAX30207. From this tab, read the contents of individual registers and manually enter the desired bit settings using a write operation. For the register address selected in the table, the bit values are displayed at the bottom of the tab and visualized as bold or non-bold bit names. When a bit is Evaluates: MAX30207 bold, its value is 1. Otherwise, the bit is 0. Full descriptions of each bit are available in the table on the right for quick reference. Pressing Read reads the selected register. Pressing Read All reads all registers and updates their values in the Registers tab. To write to a register, set the desired bit values by clicking on the bit names to make bold or non-bold, and then select Write. Figure 7.

The board contains jumpers to test the MAX30207 under several conditions. A list of all jumpers and their respective functions is available in Table 1. The EV system utilizes the MAX32630FTHR CortexM4F Microcontroller for wearables to interface with the GUI and optionally provide power to the MAX30207. The MAX32630FTHR operates either from a host PC or directly from a Li+ battery. If an SD card is present in the MAX32630FTHR, pressing SW2 on the MAX32630FTHR initiates measurements and saves log files to the SD card. Logging is stopped by pressing SW2 a second time. Powering the EV Kit The MAX30207 EV kit is powered directly from the MAX32630FTHR through either a lithium-ion battery or a USB to Micro-USB cable. J3 must be connected to the 1.8V option to supply power from the MAX32630FTHR. J9 and J10 can be used to connect the interface board, through wires, to another board that contains the MAX30207 IC. Table 1. Description of Jumpers JUMPER DESCRIPTION J3-1 to J3-2 Connect VCC to 1.8V of the MAX32630FTHR. J5-1 to J5-2 Connects GPIO0_INTB to 4.7kΩ pullup (optional). J6-1 to J6-2 Connect SCL to 4.7kΩ pullup. J7-1 to J7-2 Connect SDA to 4.7kΩ pullup. J8-1 to J8-2 Select the 1-Wire communication protocol by connecting ‘DS2484’. J9 Connects each signal from the interface board to the flex module connector and the J10 terminal block. Ground (pin 1 and 2) and DQ (pin 11 and 12) must be connected.
