1Introduction

This document describes the ezPyroTM Gesture/Motion Recognition Evaluation Kits and the related software. The

purpose of these kits is to enable engineers and technicians to carry out simple and effective evaluation of ezPyroTM

Gesture/Motion sensors, experiment with a sample Gesture/Motion Recognition algorithm, and to capture

measured data to a PC.

There are four variants of the ezPyroTM Gesture/Motion Recognition Evaluation Kit, see Table 1.

The kits are based on the ST microelectronics STM32F303K8 microcontroller.

Please note: The software discussed in this document can only be used with the ezPyroTM Gesture/Motion

Recognition Evaluation Kits.

2.2 Kit contents

1. ezPyroTM Gesture/Motion Evaluation Kit

2. Micro USB-to-USB cable

3. ezPyroTM Gesture/Motion Recognition software (Setup file included in software package)

4. USB drive with software and documentation

2.3 Minimum system requirements

1. Microsoft® Windows PC (all versions supported currently)

2. GB of RAM

3. 450 MB of available hard-disk space for installation, additional free space required for storing CSV files

4. 1024x768 display (1280 x 1024 recommended)

5. Local administrative rights to install device drivers

6. .NET Framework 4.5

7. 1 free USB port

3Installation

3.1 Install the ezPyroTM software

From the software pack included with the kit, select the “setup.exe” file that has this icon. This will start the

installation process.

Follow the on-screen instructions and enter the information required.

Figure 4: Installer window

ezPyroTM Gesture/Motion Evaluation Kit User Manual

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.

4Installing 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 64bit system or “dpinst_x86.exe” if you have a 32bit system. This will install the

USB driver for the ST microcontroller that is connected to the ezPyroTM board.

Once the driver has been installed the USB cable can be connected between the ezPyroTM Board and the computer.

Once connected the green light on the ezPyroTM 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).

5Installing .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.

5.1 Connect the demo kit

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.

6Running the Software

Double clicking on the .exe file will open the application. This will open the window shown below:

To connect to the demo kit, select the Device -> Connect to Device

This will open a window with all available devices on COM ports.

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, during which 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.

6.1 Different Variations

The software will work out when it is plugged in which kit it is attached to. The left side of the window then shows

the current sensing mode. The button for the active mode, gesture, direction, or presence, is highlighted in blue.

Using kits dPYEGE01, dPYEGE02 or dPYEMO02 allows access to gesture/direction and presence sensing. dPYEMO01

only allows access to presence sensing.

The main window includes four scopes

which show the signals produced by each

of the pixels in the sensor as shown in

Figure 11. The scope settings can be

altered using the sliding scales on the x-axis

and the y-axis.

Figure 11: Scope layout

By selecting Oscilloscope Full View in the Options menu, the sliding scales can

be removed.

Figure 12: Options menu

This allows the scopes to be view without

distraction.

The main window also contains a console which displays detected messages as well as any changes or errors, such as

initial start-up mode or conversion to presence sensing.

7Navigating the Menus

The main window contains 4 sections: Algorithm, ASIC Control, Wake-Up, and System

7.1 Algorithm Tab

Figure 15: Algorithm tab window

The algorithm tab gives the user access to some basic settings that can be changed.

Window Size: This is window width in samples used to detect event. A larger window width allows slower

events to be detected. A smaller window width means that an event is still registered in the scopes, but the

direction icon might not activate.

•Range: 10 to 2000

•Typical: 400

Detection Threshold: This is how high the peak value must be before the event is recognised as valid.

•Range: 1 to 20

•Typical: 3

Peak Speed

Once altered these can be reset to the default values using the Set Defaults button at the bottom of the tab window.
