STEVAL-MKI072V1
MEMS demonstration board based on the LY3100ALH
analog output single-axis gyroscope
Features
■Two working modes:
– analog (AWM)
– digital (DWM)
■RoHS compliant
Description
The STEVAL-MKI072V1 is a demonstration board
designed to provide the user with a complete,
ready-to-use platform for demonstration of ST
MEMS devices in the LY3100ALH product family.
The kit includes a sensing element and an IC
interface capable of translating information from
the sensing element into a measured signal that
can be used for external applications.
In addition to the MEMS sensor, the
demonstration board uses an ST7 microcontroller
which functions as a bridge between the sensor
and the PC. This makes it possible to download
the graphical user interface (GUI) from the
website or to use dedicated software routines for
customized applications.
The STEVAL-MKI072V1 demonstration board has
been designed for use in two different working
modes: analog and digital.
In analog working mode (AWM), the
microcontroller on the board is disabled and the
analog outputs of the device are available to the
user on a dedicated connector. This is the default
working mode when the power supply is applied
either through the USB connector or through the
supply connector.
In digital working mode (DWM), the
microcontroller on the board is enabled and it
allows the user to digitally acquire the output
signals of the device, to see them on the PC
through the dedicated GUI, and to control the
control pins of the device.
