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 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.

    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}.
