Getting started with the iNEMO™ STEVAL-MKI062V2

Introduction

The STEVAL-MKI062V2 is the second generation of the iNEMO modules family. It combines

accelerometers, gyroscopes, and magnetometers with pressure and temperature sensors to

provide 3-axis sensing of linear, angular, and magnetic motion, complemented with

temperature and barometer/altitude readings, representing the new ST 10-degrees of

freedom (DOF) platform.

This document provides a quick start guide for iNEMO PC software and graphical user

interface (GUI).

iNEMO V2 GUI installation UM1010

4/18 Doc ID 18054 Rev 1

1 iNEMO V2 GUI installation

The installation of the graphical user interface (GUI) requires the following two steps:

1. Install the PC software delivered with the demonstration kit

2. Install the virtual COM driver needed to use the board

1.1 PC system requirement

●Microsoft Windows XP®Service Pack 2, or higher

●Microsoft.NET Framework 2.0 (or higher)

1.2 PC software installation

To install the iNEMO suite, run the setup file and follow the instructions.

Note: The latest setup file is available on st.com.

1.3 Virtual Com driver installation

To install the virtual COM driver, plug the iNEMO board into a free USB port, an icon should

appear in the “Notify Bar”, as in Figure 2. Wait for the “Hardware Update Wizard” window

and follow the instructions in Figure 4.

Figure 2. STEVAL-MKI062V2 notification icon

Note: If, after a few seconds, the “Hardware Update Wizard” doesn`t appear, follow the

instructions given in Figure 3 and then in 4.

Once the installation has finished, a COM port number is assigned to the ST virtual COM

driver (Figure 5). Knowledge of this number is required to correctly run the iNEMO GUI.

iNEMO suite UM1010

8/18 Doc ID 18054 Rev 1

2 iNEMO suite

The iNEMO suite application allows the user to work both with the iNEMO V1 and iNEMO

V2 platform. At the startup of the application, the kit selector window appears, to choose the

platform used (Figure 6).

The iNEMO suite application is based on the software development kit (SDK)

iNEMO_SDK.dll (for STEVAL-MKI062V1) and iNEMO2_SDK.dll (for STEVAL-MKI062V2).

Only for the STEVAL-MKI062V2 is the iNEMO suite application also a TCP/IP server for

external/remote demo applications; when the server starts, in the log bar a message shows

the availability of the server. Each client may be connected to the server on port

31001(default) to receive data from the device through the iNEMO suite (server).

Every time a client is connected to the server the log bar shows the IP address of the client

just connected.

Each demo (client) could elaborate and show these data. (The structure of the data sample

sent to all clients is the FrameData_t defined in the iNEMO2_SDK.h).

The TCP/IP server may be enabled/disabled from the Tools->Communication->Settings

menu (its state is shown on the status bar below). From this dialog box, the user can change

the communication port (default 31001). Pay close attention to this information in order to

avoid a communication block from an installed firewall.

To run the INEMO suite:

1. Click on Start > All Programs > STMicroelectronics > iNEMO Suite > iNEMO Suite

Application

2. Launch the program iNEMO software tool (Goldfish Icon)

3. At first, the “Kit Selector” window appears (Figure 6). Select STEVAL-MKI062V2

4. Check that the serial port number is correct (see Figure 5). Otherwise click the refresh

button and choose the right COM port.

It is preferable to connect the iNEMO board to a free USB port before launching the GUI. In

this way, the GUI directly finds the COM port into which the board is plugged.

To change COM port press the “New” button on the toolbar or from the menu File/New and

the kit selector dialog appears.

2.1 iNEMO suite main window

The main window is made up of the following main sections (Figure 7):

1. Sensor selector, where the user can move to a different sensor data view

2. Toolbar for data acquisition setting, to set frequency, acquisition mode, etc.

3. Toolbar for graphic management, helps the user to explore in the graphic window. It

allows to zoom the graph, enabling cursors, save data, and so on

4. Status bar shows the acquisition info

5. Log window

6. Default menu bar

7. The graphical panel, where the data are graphically represented

2.2 Connecting iNEMO

Before starting the acquisition, it is necessary to open the connection between the iNEMO

and the PC. It is preferable to connect the iNEMO board to a free USB port before launching

the GUI. In this way, the GUI directly finds the COM port into which the board is plugged.

On the bottom part of the GUI main window the COM port number is reported, Figure 8:

Figure 8. Selected COM port number

The user must check if the COM port number is the same as the one shown in the device

manager (Figure 5).

If the COM number is different, it is necessary to set the right number. By clicking the new

data file icon (Figure 9) the kit selector window appears and it is possible to select the COM

port number as in Figure 6.
