Demonstration kit description
The eMotion is a complete demonstration kit that allows demonstration of both digital and
analog MEMS sensors. Thanks to its DIL 24 connector, a wide range of MEMS adapter
boards can be used.
The block diagram of the demonstration kit is shown in
Figure 1
.
Figure 1. Demonstration board block diagram
As shown in the
Figure 1
, the eMotion demonstration kit is based on the STM32F103RET6
microcontroller and can be connected to the PC through the USB bus. Data coming from the
MEMS sensor connected to the board can be read through the PC GUI provided with the kit.
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. Moreover, the eMotion
integrates three buttons: two are available to the user on a dedicated GPIO of the
microcontroller, while the other is used as reset for the microcontroller.
All the MEMS adapter pins are available on two connectors placed on the board (
Figure 2
JP2 and JP3).
The top silkscreen view and image of the full board are shown in
Figure 2
and
Figure 3
respectively.
