STEVAL-MKI109V1 and STEVAL-MKI109V2 - eMotion
motherboards for MEMS adapter boards
Introduction
The STEVAL-MKI109V1 and STEVAL-MKI109V2 (eMotion) are two motherboards designed
to provide the user with a complete ready-to-use platform for the demonstration of MEMS
devices mounted on adapter boards.
The STEVAL-MKI109V1 demonstration board uses an STM32F102RB microcontroller while
the STEVAL-MKI109V2 uses an STM32F103RET6 microcontroller; these function 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 and run the demonstration kit user interface.
For details regarding the features of each sensor, please refer to the datasheets available for
each individual device.

    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 release. The eMotion also integrates three general purpose LEDs, two LEDs connected directly to the interrupt pins of digital adapters and the power/USB LED.

  • Page 14: Supported Commands

    Supported commands UM0979 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.

  • Page 16 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}.

The values shown on the screen correspond to the LSB data shown as a decimal number.
  • Page 19 UM0979 Supported commands 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 STM32F10xRx microcontroller mounted on the demonstration kit. These commands allow the isolation of the sensor from the microprocessor and let the user to interact with the sensor in a pure analog way.
