1 Demonstration kit description

The Professional MEMS Tool is a complete demonstration kit for digital and analog MEMS sensors. Thanks to itsDIL24 connector, a wide range of MEMS adapter boards can be used.

Figure 1. Demonstration board block diagram

The Professional MEMS Tool demonstration kit is based on the STM32F401VE microcontroller and can beconnected to a PC via USB. Data from MEMS sensors connected to the board can be read through the PC GUIprovided with the kit.The Professional MEMS Tool also implements the DFU (device firmware upgrade) feature, so it can bereprogrammed with a new firmware release without the need to use a programmer (see www.st.com/mems).The Professional MEMS Tool integrates:• Six LEDs:

– two LEDs connected via FET buffers to the interrupt pins of digital adapters– a power/USB LED– three general-purpose LEDs for firmware state indication

• Three buttons:– two user buttons on a dedicated GPIO of the microcontroller– a microcontroller reset button

All the MEMS adapter pins are available on board connectors J1 and J3.

2 Professional MEMS Tool board installation

The software packages can be downloaded from the st.com website; it is arranged in the following directorystructure:• DRIVER: it contains the installation package for the USB drivers needed to connect the Professional MEMS

Tool board to the PC. No driver is needed on Linux and Mac OS platforms, so this directory is included in theWindows installation package only.

• DFU: it contains the .dfu files and the installation package for the software needed to upgrade the firmwareof the Professional MEMS Tool board.

• FIRMWARE: it contains the source code of the firmware of the Professional MEMS Tool board together withthe corresponding binary file that can be flashed to the board using the DFU software.

2.1 Hardware installation (Windows® platforms)• For Linux® and Mac OS® platforms, no driver installation is required.• For Windows platforms, install the STM32 virtual COM port driver by running VCP_V1.4.0_Setup.exe in the

DRIVER folder of the Windows installation package and follow the instructions.

Once the driver is installed, connect the demonstration kit board to a free USB port. A confirmation messageshould appear.

Figure 5. Successful device driver installation

Confirm which COM port has been assigned to the board: right click on My Computer and select Manage, thenselect Device Manager and scroll through the list to Ports (COM & LPT).

Note: The STM32 virtual COM port driver for Windows platforms and related documents are packaged with the STSW-STM32102 software download at www.st.com

4 Supported commands

The microcontroller mounted on the Professional MEMS Tool board is equipped with dedicated firmware thatallows control of the digital output MEMS sensor, and acquisition of the measured data.The firmware also handles the communication between the board and the PC through the USB bus.

4.1 Getting startedBefore using the commands supported by the firmware, the following procedure must be performed:

Step 1. Connect the Professional MEMS Tool to the USB portStep 2. Launch an application that allows sending commands through the virtual serial port. The remainder of

this document assumes the use of Microsoft® HyperTerminal program available with the Windows XPoperating system, but you can use any similar tool.

Step 3. Create a new connection, enter a name (e.g. STEVAL-MKI109V3), and click OK.Step 4. In the Connect Using field, select the virtual COM port to which the USB port has been mapped, and

click OK.Step 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 OKStep 6. In the HyperTerminal application window, select files > properties > settings, then click

ASCII Setup.Step 7. Select Send line ends with line feeds and Echo typed characters locallyStep 8. Click OK to close the ASCII Setup windowStep 9. Click OK button to close the Properties window.

Once this procedure has been completed you can use the commands described in the followingsections by typing them in the “HyperTerminal” window.

4.1.1 Quick startThe basic sequence of commands (based on the LIS3DH accelerometer) to start a data communication sessionand to retrieve X, Y, and Z acceleration data from the demonstration kit is:

Step 1. Connect the Professional MEMS Tool to the USB portStep 2. Start “Microsoft© HyperTerminal” (or another similar application) and configure it as described in

Section 4.1 Getting startedStep 3. Enter the *setdb105v1 command in the HyperTerminal” window, (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 STM32F401VE microcontroller,and *w2047 to switch on the LIS3DH and to set the data rate to 50 Hz

Step 4. Send the *debug command to get the X, Y, and Z data measured by the sensorStep 5. Send *stop to end the continuous acquisition and visualization.

4.2 Supported commandsThe firmware supports a wide range of MEMS adapters; the complete list of supported commands and theirdescriptions are given below. Commands are not case sensitive.

4.2.1 *setdbXXXVYThis command selects the part of the firmware able to handle the adapter board sensor connected to the board.For example, *setdb105V1 selects the firmware for the LIS3DH.The D3 LED (yellow) switches on automatically.

4.2.2 *startThis command initiates continuous data acquisition. When sent, the device returns a string of bytes (plus carriagereturn and line feed) like st OUT1 OUT2 OUT3 IR STP 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 contain the values measured at device outputs; if the output data is represented in morethan 8 bits, OUT1, OUT2, and OUT3 are split into high byte (e.g., XH) and low byte (e.g., XL). In case of 24-bitresolution for some sensors, there is also an extra-low byte (e.g., pressure data: PXL PL PH).IR (INT1 INT2) contains the interrupt bytes and BT SW1|SW2 contains the bytes that describe the state of thebuttons integrated on the board.


UM2116 - Rev 3 page 13/39

Specifically, bit#0 of the SW1|SW2 data corresponds to the status of the SW1 button on the demonstration kitboard: it is set to 1 when the SW1 is pressed (otherwise 0). Bit#1 has the same behavior but is dedicated to theSW2.STP (STPL STPH) contains the step counter bytes for the internal device step counter value.The string is ended with the carriage return (\r) and line feed (\n) bytes.Before sending the *start command, the device must be out of 3-state (high impedance) and some registersmust be configured according to user needs. Therefore, *start must be preceded by a * zoff and someRegister Write commands.As data is continuously acquired, LED D1 (green) blinks according to sensor data rate selected. Table3. Returned values for *start command shows the format of the string returned for each device when a *startcommand is sent. Similar byte strings are returned for groups of commands related to FIFO, as is shown in Table4. Digital output accelerometers: supported commands list, Table 5. Digital output gyroscopes: supportedcommands list, Table 6. Digital output magnetometer: supported commands list, Table 7. Digital output pressuresensor: supported commands list and Table 8.

4.2.3 *debugThis command starts continuous data acquisition in debug mode. When sent to the board, it returns the outputvalues measured by the device formatted in a readable text format.

4.2.4 *stopThis command interrupts any acquisition session that has been started with either the *start or *debugcommands.

4.2.5 *Zon and *ZoffThese commands put the STM32F401VE microcontroller on the demonstration kit in 3-state (high impedance).They allow the isolation of the sensor from the microprocessor and let the user interact with the sensor in a purelyanalog fashion.When the kit is first turned on, the lines are in 3-state (high impedance) mode and you must send the * Zoffcommand to allow communication between the sensor and the microcontroller.After this command has been executed, LED D2 (Red) is turned on.
