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.

some main components placed on the top layer of the eMotion kit are highlighted.

• Jumpers JP9 and JP10 (

, 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 (

series with its terminals ( Figure 3. Board top view , ref 9).

, 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

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.

UM0979 eMotion board installation

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.

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

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

2.2.1

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.

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”.

DFU

2.2.2

2.2.3

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.

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.

Supported commands

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.

Getting started

Before using the commands supported by the firmware, the following procedure must be performed:

Connect the eMotion to the USB port

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

Create a new connection, enter a name (e.g. “STEVAL-MKI109V2”), and click “OK”

In the “Connect Using” field, select the virtual COM port to which the USB port has been mapped, and click

“OK”

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”

In the “HyperTerminal” application window choose “files” > “properties” > “settings”, then click on the “ASCII

Setup” button

Select “Send line ends with line feeds” and “Echo typed characters locally”

Click the “OK” button to close the “ASCII Setup” window

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.

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.

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.

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

UM0979 - Rev 6

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.

page 19/39

UM0979 - Rev 6

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.

Accelerometer FIFO mode enable
