STEVAL-MKI109V2: eMotion motherboard for MEMS adapter boards
Introduction
The STEVAL-MKI109V2 (eMotion) is a motherboard designed to provide the user with a complete ready-to-use platform for the
demonstration of MEMS devices mounted on adapter boards.
The STEVAL-MKI109V2 uses an STM32F103RET6 microcontroller which functions as a bridge between the sensor on the
adapter board and the PC on which it is possible to use the Unico graphical user interface (GUI) downloadable from the ST
website or dedicated software routines for customized applications.
This user manual describes the hardware included with the demonstration kit and provides the information required to install the
demonstration board and how to upgrade the firmware of the microcontroller.
For details regarding the features of each sensor, please refer to the datasheet available for each individual device.

The eMotion is a complete demonstration kit that allows demonstration of both digital and analog MEMS sensors.
Thanks to its DIL 24 connector, a wide range of MEMS adapter boards can be used.
The block diagram of the demonstration kit is shown in Figure 1. Demonstration board block diagram.

UM0979
Demonstration kit description
As shown in the Figure 1. Demonstration board block diagram, the eMotion demonstration kit is based on the
STM32F103RET6 microcontroller and can be connected to the PC through the USB bus. Data coming from the
MEMS sensor connected to the board can be read through the PC GUI provided with the kit.
The eMotion also implements the DFU (device firmware upgrade) feature, therefore, in the case of a new
firmware release, it can be reprogrammed without the need to use a programmer. See www.st.com/mems for new
firmware releases.
The eMotion also integrates three general-purpose LEDs, two LEDs connected directly to the interrupt pins of
digital adapters and the power/USB LED. Moreover, the eMotion integrates three buttons: two are available to the
user on a dedicated GPIO of the microcontroller, while the other is used as reset for the microcontroller.
All the MEMS adapter pins are available on two connectors placed on the board (Figure 2. Top silkscreen of the
eMotion kit JP2 and JP3).
The top silkscreen view and image of the full board are shown in Figure 2. Top silkscreen of the eMotion kit and
Figure 3. Board top view respectively.

Demonstration kit description
In order to use the eMotion demonstration kit, installation of a dedicated driver is required, which is included in the
installation pack, together with a GUI interface which allows simple interaction with the sensor. The steps required
for driver and software installation are described in the following sections.
In Figure 3. Board top view some main components placed on the top layer of the eMotion kit are highlighted.
• Jumpers JP9 and JP10 (Figure 3. Board top view, ref 10, ref 11) are used to select the STM32 boot mode.
When the eMotion is used together with MEMS adapters, JP9 and JP10 must be fitted (see STM32
datasheet for more information).
• Jumper J2 (Figure 3. Board top view, ref 7) can be used to directly supply the board (from 3.5 V to 6 V)
instead of using the USB connector.
• Jumper JP1 allows the user to measure the sensor current consumption by connecting a multimeter in
series with its terminals (Figure 3. Board top view, ref 9).
• Jumpers JP4, JP5, and JP6 (Figure 3. Board top view, ref 8) are used to manually set some features which
are available for just some of the analog MEMS adapters (see Table 1. Jumper configuration for power-down
(PD), self test (ST), and high-pass filter reset (HP) for more details). JP4 is used to set the self-test feature,
JP5 to handle the power-down pin, and JP6 to reset the MEMS high-pass filter. When they are fitted on pins
2-3, these functions are handled by the firmware itself.

• J1 connector (Figure 3. Board top view, ref 3) can be used to both reprogram the STM32 and to debug the
code through the JTAG or SWD protocols.
• Jumper JP7 (Figure 3. Board top view, ref 4) is used to select either JTAG (JP7 unfitted) or SWD (JP7 fitted)
mode.
• eMotion also integrates six LEDs and three buttons:
– LED D1 (Figure 3. Board top view, ref 6) is switched on when the board is power supplied.
– LEDs D2 and D3 (Figure 3. Board top view, ref 13) are directly connected to the interrupt pins of the
MEMS digital adapters (if available on the sensor mounted on the adapter board).
– LEDs D4, D5, and D6 (Figure 3. Board top view, ref 12) are general-purpose LEDs and are used to
indicate firmware states. For example, LED D6 is switched on when a specific firmware is selected
from those available. LED D5 on indicates that the microcontroller is well configured for communication
with the sensor. Finally the LED D4 blinks according to the sensor data rate selected.
– Button SW3 (Figure 3. Board top view, ref 1) is used to reset the STM32.
– Button SW1 and SW2 (Figure 3. Board top view, ref 2 and ref 5) are connected to STM32 GPIOs and
are available to the user.

2 eMotion board installation
The software package can be downloaded from the st.com website and includes the following directory structure:
• DRIVER: it contains the installation package for the USB drivers needed to connect the eMotion board to the
PC. No driver is needed on Linux and Mac OS platforms, so this directory is included in the Windows
installation package only.
• DFU: it contains the .dfu files and the installation package for the software needed to upgrade the firmware
of the eMotion board.
• FIRMWARE: it contains the source code of the firmware of the eMotion board together with the
corresponding binary file that can be flashed to the board using the DFU software.
The section below describes the procedure to install the driver for the eMotion board (needed on Windows
platforms only) and the DFU software.
2.1 Hardware installation (Windows platforms)
No driver installation is needed on Linux and Mac OS platforms.
To install the STM32 virtual COM port driver on Windows platforms, launch the “VCPDriver_V1.4.0_Setup.exe”
included in the Windows installation package under the “DRIVER” folder and follow the instructions on the screen.
Once the driver is installed, insert the demonstration kit board into a free USB port. A notification message should
appear, as in Figure 5. Notification message.
UM0979
eMotion board installation
Figure 5. Notification message
Now the eMotion should be recognized by the PC as a virtual COM. In order to confirm which COM port has been
assigned to the board, right click on “My Computer” and select “Manage”, select “Device Manager” and scroll
through the list until “Ports (COM & LPT)”. In the following example (Figure 6. Virtual COM port assignment) the
COM11 has been assigned to the board.

DFU
2.2 DFU
The MEMS STEVAL-MKI109V2 demonstration board is capable of reprogramming an application through the
USB, in accordance with the DFU class specification defined by the USB Implementers Forum. This capability is
useful because it allows reprogramming the microcontroller directly in the field and is particularly well-suited to
USB applications where the same USB connector can be used both for the standard operating mode and for the
reprogramming process.
In order to configure the eMotion board in DFU mode button SW2 must be pressed before supplying the board
and released when the LEDs D1, D4, D5, and D6 light up.
If the firmware version in use is lower than V3.0.0, it’s mandatory to patch the DFU feature using the
“DFU_Patcher_V1.0.2.dfu” file available under the “DFU” folder before proceeding with the upgrade of the
firmware with a version equal to or higher than V3.0.0. The procedure to patch the DFU feature corresponds to
the one used during a standard firmware upgrade with the DFU tool. At the end of this procedure, if the green
LED D4 is on, it indicates that the procedure is successfully completed; if the red LED D5 is on, the procedure
failed and has to be repeated. Before proceeding with the new firmware upgrade the board must be reset using
the SW3 button.
2.2.1 DFU on Windows
To install the DFU software, launch the “DfuSe_Demo_V3.0.5_Setup.exe” included in the software package under
the “DFU” folder and follow the instructions on the screen. To launch the software, select “Start >
STMicroelectronics > DfuSe > DfuSe Demonstration”.
In the ‘Upgrade or Verify Action’ section of the Dfuse Demo tool click on the ‘Choose...’ button and select the
target .dfu file; then click the ‘Upgrade’ button to start the firmware upgrade.
For more details regarding DFU and the microcontroller ST GUI, see the related user manual located under “Start
> STMicroelectronics > DfuSe > Docs > DfuSe Getting Started”.
UM0979 - Rev 6
page 8/39

2.2.2 DFU on Linux
The DFU program used for Linux operating systems is ‘dfu-util’.
The procedure for Ubuntu Linux operating systems is described below.
To install this program, open a terminal and write the following command (with sudo to ensure having the correct
permissions):
sudo apt-get install dfu-util
Create a udev rules file:
sudo gedit /etc/udev/49-emotion.rules
and fill it with the following content:
# 0483:5740 - STM32F4 in USB Serial Mode (CN5) ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740",
ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE:="0666"
# 0483:df11 - STM32F4 in DFU mode (CN5) SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483",
ATTRS{idProduct}=="df11", MODE:="0666"
Tell udev to reload its rules:
sudo udevadm control --reload-rules
You should now be able to program the board. So, connect the eMotion board in DFU mode, and run the following
command:
sudo dfu-util -a 0 -D dfu_path/file.dfu -d 0483:df11
where dfu_path and file.dfu are the path to the dfu file and the dfu file name respectively
(example: sudo dfu-util -a 0 -D Desktop/eMotionV2_REL_4_0.dfu -d 0483:df11).
To use the board with the upgraded firmware you need to disconnect and reconnect it, in order to exit DFU mode.
UM0979
DFU
2.2.3 DFU on Mac OS
The DFU program used for Mac operating systems is ‘dfu-util’. Before installing it, you need to install Homebrew.
To do that, you need to open a terminal and run the following command:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Once Homebrew is installed on your Mac, you can install dfu-utils with the following command:
brew install dfu-util
You should now be able to program the board. So, connect the eMotion board in DFU mode, and run the following
command:
dfu-util -a 0 -D dfu_path/file.dfu -d 0483:df11
where dfu_path and file.dfu are the path to the dfu file and the dfu file name respectively
(example: dfu-util -a 0 -D Desktop/eMotionV2_REL_4_0.dfu -d 0483:df11).
To use the board with the upgraded firmware you need to disconnect and reconnect it, in order to exit DFU mode.

4 Supported commands
The microcontroller mounted on the eMotion board is equipped with dedicated firmware that supports a set of
commands which allow to control either the digital or the analog output MEMS sensor and permits the acquisition
of the measured data. The firmware also handles the communication between the board and the PC through the
USB bus. These features allow the user to easily write their own applications to exploit the capabilities of the
sensor chosen.
This section describes the commands that are supported by the firmware for the microcontroller of the eMotion
demonstration kit.
4.1 Getting started
Before using the commands supported by the firmware, the following procedure must be performed:
1. Connect the eMotion to the USB port
2. Launch an application which allows to send commands through the virtual serial port. The remainder of this
document assumes the use of “Microsoft© HyperTerminal” program available with the Windows XP operating
system
3. Create a new connection, enter a name (e.g. “STEVAL-MKI109V2”), and click “OK”
4. In the “Connect Using” field, select the virtual COM port to which the USB port has been mapped, and click
“OK”
5. In port settings, set bits per second to 115200, data bits to 8, parity to none, stop bits to 1, and flow control to
none. Click “OK”
6. In the “HyperTerminal” application window choose “files” > “properties” > “settings”, then click on the “ASCII
Setup” button
7. Select “Send line ends with line feeds” and “Echo typed characters locally”
8. Click the “OK” button to close the “ASCII Setup” window
9. Click the “OK” button to close the “Properties” window.
Once this procedure has been completed, the user can utilize the commands described in the following sections
by typing them in the “HyperTerminal” window.

Note: IR: interrupt byte; FC: FIFO control register; FS: FIFO source register.
Set demonstration board
The command *setdbxxxvy selects the part of the firmware able to handle the adapter board sensor connected to
the board. e.g., in order to select the firmware for the LIS3DH the command must be: *setdb105V1. The D6 LED
(green) is automatically switched on.
Start command
The *start command initiates the continuous data acquisition. When this command is sent to the device, it returns
a string of bytes (plus carriage return and line feed) similar to “st OUT1 OUT2 OUT3 IR BT”.
The first two bytes are always the ASCII char “s” and “t” which correspond to the hexadecimal values {73h 74h}.
OUT1, OUT2, and OUT3 are the bytes that contain the values measured at device outputs; if the output data is
represented on more than 8 bits, OUT1, OUT2, and OUT3 are split into two bytes: high byte (e.g.: “XH”) and low
byte (e.g.: “XL”).
IR contains the interrupt bytes and BT contains the bytes that describe the state of the buttons integrated on the
board.

Supported commands
Specifically, bit#0 of the “BT” data corresponds to the status of the SW1 button on the demonstration kit board: it
is set to 1 when the SW1 is pressed (otherwise 0). Bit#1 has the same behavior but is dedicated to the SW2.
Before sending the *start command, the device must be out from 3-state and some registers must be configured
according to user needs, therefore, *start must be preceded by a *zoff and some “Register Write” commands.
Table 4. Returned values for *start command shows the format of the string returned for each device when a *start
command is sent.

Stop command
The *stop command interrupts any acquisition session that has been started with either the *start or *debug
commands.
Zon and Zoff
The *Zon and *Zoff commands are employed, respectively, to put into 3-state the STM32F103RET6
microcontroller mounted on the demonstration kit. These commands allow the isolation of the sensor from the
microprocessor and let the user interact with the sensor in a pure analog way.
By default, when the kit is first turned on, the lines are in 3-state mode and the user is required to send the *Zoff
command to allow communication between the sensor and the microcontroller. If Zoff has not been launched, the
firmware ignores any other command.
Device name
The *dev command retrieves the name of the adapter connected to the demonstration kit. The returned value is,
for example, “LIS3DH”.
Firmware version
The *ver command queries the demonstration kit and returns the version of the firmware loaded in the
microprocessor, for example, “V1.0”.
Accelerometer register read
The *rAA command allows the contents of the accelerometer registers in the demonstration kit board to be read.
AA, expressed as a hexadecimal value and written in upper case, represents the address of the register to be
read.
Once the read command is issued, the board returns RAAhDDh, where AA is the address sent by the user and
DD is the data present in the register.
For example, to read the register at address 0x20, the user issues the command *r20, which returns, e.g.,
R20hC7h.
UM0979 - Rev 6
Accelerometer register write
The *wAADD command allows writing to the contents of the accelerometer registers in the demonstration kit
board. AA and DD, expressed as hexadecimal values and written in upper case, represent, respectively, the
page 18/39
Page 19
UM0979
Supported commands
address of the register and the data to be written. For example, to write 0xC7 to the register at address 0x20, the
user issues the command *w20C7.
Gyroscope register read
The *grAA command allows the contents of the gyroscope registers in the demonstration kit board to be read. AA,
expressed as hexadecimal value and written in upper case, represents the address of the register to be read.
Once the read command is issued, the board returns GRAAhDDh, where AA is the address sent by the user and
DD is the data present in the register.
For example, to read the register at address 0x20, the user issues the command *gr20, which returns, e.g.,
GR20hC7h.
Gyroscope register write
The *gwAADD command allows writing to the contents of the gyroscope registers in the demonstration kit board.
AA and DD, expressed as hexadecimal values and written in upper case, represent, respectively, the address of
the register and the data to be written. To write 0xC7 to the register at address 0x20, for example, the user issues
the command *gw20C7.
Magnetometer register read
The *mrAA command allows the contents of the magnetometer registers in the demonstration kit board to be
read. AA, expressed as a hexadecimal value and written in upper case, represents the address of the register to
be read.
Once the read command is issued, the board returns MRAAhDDh, where AA is the address sent by the user and
DD is the data present in the register.
For example, to read the register at address 0x00, the user issues the command *mr00, which returns, e.g.,
MR00h10h.
Magnetometer register write
The *mwAADD command allows writing to the contents of the magnetometer registers in the demonstration kit
board. AA and DD, expressed as hexadecimal values and written in upper case, represent, respectively, the
address of the register and the data to be written. To write 0x20 to the register at address 0x01, for example, the
user issues the command *mw0120.
Pressure sensor register read
The *prAA command allows the contents of the pressure sensor registers in the demonstration kit board to be
read. AA, expressed as a hexadecimal value and written in upper case, represents the address of the register to
be read.
Once the read command is issued, the board returns PRAAhDDh, where AA is the address sent by the user and
DD is the data present in the register.
For example, to read the register at address 0x20, the user issues the command *pr20, which returns, e.g.,
PR20h10h.
Pressure sensor register write
The *pwAADD command allows writing to the contents of the pressure sensor registers in the demonstration kit
board. AA and DD, expressed as hexadecimal values and written in upper case, represent, respectively, the
address of the register and the data to be written. To write 0xC7 to the register at address 0x20, for example, the
user issues the command *pw20C7.
Humidity sensor register read
The *hrAA command allows the contents of the humidity sensor registers in the demonstration kit board to be
read. AA, expressed as a hexadecimal value and written in upper case, represents the address of the register to
be read.
Once the read command is issued, the board returns HRAAhDDh, where AA is the address sent by the user and
DD is the data present in the register.

UM0979
Supported commands
For example, to read the register at address 0x20, the user issues the command *hr20, which returns, e.g.,
HR20h10h.
Humidity sensor register write
The *hwAADD command allows writing to the contents of the humidity sensor registers in the demonstration kit
board. AA and DD, expressed as hexadecimal values and written in upper case, represent, respectively, the
address of the register and the data to be written. To write 0xC7 to the register at address 0x20, for example, the
user issues the command *hw20C7.
Single acquisition
The *single command may be used to read just one set of data. It requires the sensor to be well configured and
once invoked, returns the read values of one data sample.
The format of the returned value is exactly the same as the *debug command (Table 5. Returned values for
*debug command), in fact, the *debug command is used for continuous data acquisition purposes whereas a
*single command returns just one set of data.
List
The *list command returns the list of MKI adapters supported by the firmware, printed in ASCII format.
Listdev
The *listdev command returns the list of devices supported by the firmware, printed in ASCII format.
Echo on
The *echoon command is used to activate the write command verbose mode. Once this command is launched,
after every write command the firmware automatically performs also a read of the register just written. This
function is useful to check if the write has succeeded. For instance, if the *echoon command is launched, after a
*w2027 it results R2027.
Echo off
The *echooff command stops the write command verbose mode.
Accelerometer FIFO reset enable
The *fiforst command enables the accelerometer FIFO reset mode. For more details see the AN3308 application
note.

Quick start
4.3 Quick start
This section shows the basic sequence of commands, based on the LIS3DH accelerometer, to start a data
communication session and to retrieve the X, Y, and Z acceleration data from the demonstration kit:
1. Connect the eMotion to the USB port
2. Start “Microsoft© HyperTerminal” and configure it as described in Section 4.1 Getting started
3. Inside the “HyperTerminal” window, enter the command *setdb105v1 (supposing the LIS3DH adapter board
is used, for other adapters see the relevant datasheets to check the register configuration), enter the
command *Zoff to enable the control of the device by the STM32F103RET6 microcontroller, and *w2047 to
switch on the LIS3DH and to set the data rate to 50 Hz
4. Send the *debug command to get the X, Y, and Z data measured by the sensor
5. Send *stop to end the continuous acquisition and visualization.
