STEVAL-MKI109V1 - eMotion
motherboard for MEMS adapter board
Introduction
The STEVAL-MKI109V1 (eMotion) is a motherboard designed to provide the user with a
complete ready-to-use platform for demonstration of MEMS devices mounted on adapter
boards.
The eMotion board uses an STM32F102RB 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 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 13: Supported Commands

    UM0979 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.

  • Page 15 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}.
