Figure 2 –Installer Screen
Follow the on screen instructions and enter the information required.
As part of the installation process a check will take place to see if .NET Framework 4.5 is
present. If not, the setup routine can be cancelled and the .NET framework 4.5 can be
downloaded from Microsoft’s website.
A driver is needed for the STM32F303K8T6 microcontroller. This is included in the software
package.
3.2 Installing the ST Microcontroller USB Driver
The USB supplied contains a folder called “en.stsw-link009.zip”. Extract the files and run
either the application “dpinst_amd64.exe” if you have a 64 bit system or “dpinst_x86.exe” if
you have a 32 bit system. This will install the USB driver for the ST microcontroller that is
connected to the SMD board.
Once the driver has been installed the USB cable can be connected between the SMD Board
and the computer.
Once connected the green light on the SMD board will be on constantly and the red light will
flash (The microcontroller is the inverse of this, red is on constantly and green flashes).
3.3 Installing .NET 4.5 Framework
If you do not have the .NET 4.5 framework installed on your computer then use the installer
provided (“dotnetfx45_full_x86_x64”) in the software package.
3.4 Connecting the SMD Gesture and Motion Sensing Evaluation Kit
1. Connect the USB cable to the kit and Windows PC

You may see a message suggesting you are required to install a device driver. Follow the on
screen instructions and download a driver from Windows Update or install from the software
package provided.
4 SOFTWARE USER GUIDE
4.1 Starting the Software
Double clicking on the .exe file will open the application. This will open the window shown
below:
Figure 3 - Software Main Page
4.2 Connecting Software to the Demo Kit
To connect to the demo kit, select the Device -> Connect to Device
Figure 2 –Device Connection
This will open a window with all available devices on COM ports.

Figure 3 –Com Port Selection
Connect to the port that is listed once the device is connected. If more than one COM port is
listed this can be checked by disconnecting the device and refreshing the list. Re-connect and
refresh the list then select the COM port that has appeared and click OK.
Once the device has been selected the software runs through a calibration sequence. Whilst
the calibration sequence is running the arrow that indicates a gesture direction will spin round
and then vanish upon completion of the calibration. This is required when using the device
without a method of stopping drafts from running across the device.
4.3 Different Variations
The software will automatically determine the type of kit when it is plugged in.

4.4 Navigating the Menus
The main window contains 4 sections: Algorithm, ASIC Control, Wake-Up and System.
4.4.1 Algorithm Tab
•The window showing current detection mode (the button for the active mode, gesture or
presence is highlighted in blue). When an event occurs, the detected event will be shown
with a direction icon.
•4 scope windows which show the signals produced by each of the pixels in the sensor.
•A console which displays detected messages as well as any changes or errors and a
simple setting window where the trigger threshold can be changed.
See below for use of parameters.

4.4.2 ASIC Control Tab
The ASIC box gives the user access to the various parameters that can be controlled on the
output of the SMD USEQ*S sensor.
-Gain: The gains should all be set equal on every channel for gesture detection. They are
allowed to be set independently simply to allow the user complete control over every
aspect of the device that can be set. The gain is set by selecting a capacitor to be used in
the charge amplifier within the device.
-High Pass Filter (HPF): The high pass filters should again be set equal for gesture
detection.
-Transconductance: The transconductance gives the user the ability to set the time
constant of the sensor and amplifier set-up.
-Low Pass Filter: The low pass filter used is common to all channels of the SMD USEQ*S
sensor.
-Sampling Period: This allows the sampling rate to be altered.

4.4.3 Wake-Up Tab
The Wake-Up box allows the setting of the wake-up conditions for the device. The wake-up
only applies when the device is in sleep mode.
•The wake-up works by requiring the signal to be within the range of threshold 1 and 2 or
within threshold 3 and 4 for a certain number of samples.
•The number of samples required is in the top right box.
•The channel that is being used for the wake-up condition is selected in the box above the
Apply button.
For more detail on wake-up conditions please refer to the KEMET Sensor Evaluation Tool
Software User Manual.
