Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Conrm that the MAX32630FTHR is rmly seated in
connectors J8 and J7 in the proper orientation.
2) Set the EV kit hardware on a nonconductive surface
to ensure that nothing on the PCB shorts together.
3) Connect the EV kit hardware to a PC with the pro-
vided USB cable. Attach the micro-USB end to the
MAX32630FTHR board and the type A end to the host
PC. Once connected, LED D1 on the MAX32630FTHR
will blink red, and LED D1 on the EV kit board will be
green.
4) Windows should automatically begin installing the
necessary device driver. The USB interface of the
EV kit hardware is congured as a COM device and
therefore does not require a unique/custom device
driver. Once the driver installation is complete, a Win-
dows message appears near the System Icon menu,
indicating that the hardware is ready to use. Do not
attempt to run the GUI before this message. If you do,
then you must close the application and restart it once
the driver installation is complete. On some versions
of Windows, administrator privileges may be required
to install the USB device.
5) Once the device drivers have been installed, download
the latest EV kit software (MAX30001G EVKitSoftware-
Install.ZIP) and extract it to a temporary folder.
6) Open the extracted ZIP folder and double-click the
.EXE le to run the installer. If a message box stat-
ing “The publisher could not be veried. Are you
sure you want to run this software?” appears, select
the Yes option.
7) When the installer GUI appears, click Next. Select
the installation paths and if a shortcut should be
created on the desktop. When prompted, press In-
stall. Once complete, click Close.
8) Double-click the shortcut to start the GUI. Alter-
natively, go to Start | All Programs. Look for the
MAX30001G EVKitSoftware folder and click on the
MAX30001G EVKitSoftware.EXE le inside the folder.
9) After the initial splash screen, when the GUI
appears, the text in the right eld of the status strip at
the bottom of the GUI window should display Hard-
ware Connected and the COM port associated with
the EV kit.
Detailed Description of Software
Software Startup
If the EV kit is connected when the software is opened,
the software rst initializes the hardware to communicate.
The software then reads the device registers and updates
all the associated control elds displayed on the GUI.
The status strip at the bottom of the GUI displays the
MAX32630FTHR rmware version, the GUI version, and
the hardware’s associated COM port.
If the EV kit is not connected on startup, the Connection
Issue dialog box shown in Figure 1 appears after the
GUI splash screen. Clicking OK opens the Connection
window of the GUI. Use the Scan Ports button to identify
all COM ports in use by the PC and select the port associ-
ated with the EV kit hardware in the COM Port drop down
menu. This window, shown in Figure 2, may appear if
connecting to the EV kit for the rst time even if the hard-
ware is connected before starting the GUI.
Once the correct COM port is selected, press Connect at
the bottom center of the GUI to enter the main window.
The program reads all device registers and updates the
control elds of the GUI.

ToolStrip Menu Bar
The ToolStrip menu bar (Figure 3) is located at the top
of the GUI window. This bar comprises the File, Device,
Options, Logging, and Help menus whose functions are
detailed in the following sections.
File Menu
The File menu contains the option to exit out of the GUI
program.
Device Menu
The Device menu provides the ability to connect
or disconnect an EV kit to the GUI. If a board is
disconnected while the GUI is open the GUI will display
Hardware Not Connected in the lower right corner. If
the device is then plugged back in, the user will be able
to navigate to the Device menu and select Connect. If
successful, the bottom right corner of the GUI will read
Device Connected and display the COM port to which
the hardware is connected.
Options Menu
The Options menu provides several settings to access
more features o󰀨ered by the GUI. Show MAX30001G
Register Names changes all the control eld names to
correspond with their register names in the data sheet.
BioZ Milliohm Scale congures the scaling on the BioZ
plot to be shown in milliohms rather than ohms for a
zoomed in the display of the BioZ measurement. Plots
Maximum Time allows the user to select how many
seconds of data they want to be shown on the plot at
one time. The selected time will still show 10 divisions
and each division will be 1/10 of the maximum time. By
default, the maximum time is 10 seconds.
Load Register Settings allows the user to quickly set up
the GUI based on previous, saved register settings. The
Save Register Settings item is used to save the current
register settings to be loaded again at a later time. The
Show Advanced Tab setting will add an extra tab in the
GUI called Advanced. The advanced tab is described in
depth in the Tab Control section of this document.
Logging Menu
The Logging menu provides a way to export accurate,
exact data that is being measured by the device. The four
log options are ECG File Log, R-To-R File Log, Pace
File Log, and BioZ File Blog. Selecting any log option
opens a prompt asking for a name for the comma-separated-
value (CSV) log le, as well as the location to save the
generated le. Figure 4 shows the GUI when creating
a log le. Data logging begins when Start Monitor is
pressed on the Plots tab and ends when Stop Monitor
is pushed. The GUI disables logging after one monitoring
session and a new le must be generated through the
Logging menu to log the next dataset.
Help Menu
The Help menu contains information that can be helpful in
aiding with any problems which may arise in the use of the
GUI. Online Documentation takes the user to the Maxim
Integrated website associated with the MAX30001G
where all documents that are associated with the part are
located. The About option displays the GUI splash screen
which tells the user which GUI version is being used.
Tab Control
The main interface structure of the GUI consists of a
tab control, where each tab contains controls relevant to
various blocks of the device. Changing these interactive
controls triggers a write operation to the MAX30001G to
update the register contents. Likewise, these controls are
refreshed when reading from the device.
Tabs responsible for conguring measurements contain
block diagrams of their respective channel. To congure a
measurement channel, select the desired values from the
drop down list items in and below the diagram. Switches
in the block diagrams open and close according to the
device conguration.
