Accelerometers

Smart motion features with ultra-low power consumption

ST’s state-of-the-art MEMS accelerometers include analog and digital sensors featuring up to ±400g
acceleration full scale and from 1.62 to 3.6 V supply voltage. Accelerometers have advanced power-
saving features that make them suitable for ultra-low-power applications. These features include low-
power mode, auto wake-up function and a FIFO buffer that can be used to store data, thus reducing the
host processor loading and system power consumption.
The small size and embedded features of ST’s accelerometers make them an ideal choice for handheld
portable applications and where long battery life is required.
The ST accelerometers can be applied in Industrial applications too and in the portfolio are present also
Automotive grade MEMS accelerometers qualified according to AEC-Q100.

The ASM330LXH is a system-in-package featuring both a 3D digital accelerometer and a 3D digital
gyroscope. It has a user-selectable full scale acceleration range of ±2/±4/±8/±16 g and an angular rate
range of ±125/±245/±500/±1000/±2000 dps. The ASM330LXH has two operating modes enabling the
accelerometer and gyroscope sensors to be either activated at the same ODR or the accelerometer can
be enabled while the gyroscope is powered down.

Open Development Environment

The STM32 Open Development Environment (STM32 ODE) is an open, flexible, easy and affordable
way to develop innovative devices and applications based on the STM32 32-bit microcontroller family
combined with other state-of-the-art ST components connected via expansion boards. It enables fast
prototyping with leading-edge components that can quickly be transformed into final designs.

The STM32 ODE is made up of four elements:

•

STM32 Nucleo development boards.

A comprehensive range of affordable development boards

for all STM32 microcontroller series, with unlimited unified expansion capability, and with integrated
debugger/programmer.

•

STM32 Nucleo expansion boards.

Boards with additional functionality to add sense, control,

connectivity, power, audio or other functions as needed. The expansion boards are plugged on top of
the STM32 Nucleo development boards. More complex functionalities can be achieved by stacking the
expansion boards.

•

STM32Cube software.

A set of free-of-charge tools and embedded software bricks to enable fast

and easy development on the STM32, including a Hardware Abstraction Layer, middleware and the
STM32CubeMX PC-based configurator and code generator.

•

STM32Cube expansion software.

Expansion software provided free of charge for use with STM32 Nucleo

expansion boards and compatible with the STM32Cube software framework.

The STM32 Open Development Environment is compatible with a number of IDEs including IAR EWARM,
Keil MDK, mbed and GCC-based environments.

FoCus on tHe new nuCleo eXpansion Board For sensors

The X-NUCLEO-IKS01A1 is a MEMS inertial and environmental sensor evaluation board system. It is compatible with the Arduino UNO R3
connector layout, and is designed around STMicroelectronics’ LSM6DS0 3-axis accelerometer + 3-axis gyroscope, the LIS3MDL 3-axis
magnetometer, the HTS221 humidity sensor
and the LPS25HB pressure sensor.
The board can also be used to evaluate the
new LSM6DS3, evolution of LSM6DS0, by
connecting the STEVAL-MKI160V1 DIL24
adapter.
The X-NUCLEO-IKS01A1 interfaces with the
STM32 microcontroller via the I

C pin, and it

is possible to change the default I

C port.

The Open Software Expansion development suite (“OpenSoftwareX”) offers drivers, middleware and application software to jump start your
STM32 design with ST products like MEMS, Bluetooth low energy, sensors, etc. It enables fast prototyping using the STM32 Open Development
Environment with leading-edge components that can quickly be transformed into final designs.
The Open Software Expansion environment is made up of several free libraries, such as:

•

Open.MEMS:

•

Sensor fusion library for STM32 platform osxMotionFX

•

Sensor carrying position for STM32 platform osxMotionCP

•

Sensor activity recognition for STM32 platform osxMotionAR

•

Sensor gesture recognition for STM32 platform osxMotionGR

•

Open.RF: BlueNRG Bluetooth Low Energy library for the most commonly-used BT smart profiles

•

Open.Audio:

•

Real-time beam forming for STM32 platform

•

Real-time sound source localization for STM32 platform

•

Real-time echo cancellation for STM32 platform

•

Bluetooth Low Energy and microphones for STM32 platform

open.mems

Open.MEMS libraries combine data from several sensors achieving the high level of accuracy required by portable and wearable devices and
other emerging applications, such as IoT.
The osxMotionFX library is the evolution of iNEMO Engine Pro sensor fusion algorithm and API, ported to the STM32 Open Development
Environment. Like its predecessor, the osxMotionFX is filtering and predictive software that uses advanced algorithms to integrate and read
real-time outputs from multiple sensors, achieving accurate position information, independently of environmental conditions. The fusion of real-
time motion-sensor data is set to significantly improve user experience by increasing accuracy, resolution, stability and response time in advanced
motion-based applications in the consumer, computer, industrial and medical fields. The osxMotionFX sensor fusion library is designed for use in
combination with the STM32F4 Nucleo development boards (NUCLEO-F401RE, F411 and F476). When installed on your PC, Open.MEMS libraries
must be activated through a licensing wizard tool (included into the osxMotionFX software package).
Additional sensor fusion libraries are also available:

•

The osxMotionAR provides real-time information on user activity (stationary, walking, fast
walking, biking, or driving)

•

The osxMotionCP provides real-time information regarding the position

•

The osxMotionGR provides real-time information on phone-related gestures such as wake
up, glance and pick up

Licensing wizard tool makes it easier
to quickly get started evaluating your

X-NUCLEO-IKS01A1

STEVAL-MKI160V1

multi-sensor, BluetootH appliCation development platForm

The BLUEMICROSYSTEM1 framework uses
Bluetooth Low Energy, inertial (e.g. motion
MEMS) and environmental (e.g. humidity,
pressure, temperature) sensors. It enables
fusing together and transmitting real-time
sensor data to a smartphone (Android- or iOS-
based) via Bluetooth. BLUEMICROSYSTEM1
provides an implementation example for the
STM32F4 Nucleo platform equipped with the
MEMS and environmental sensor expansion
board (X-NUCLEO-IKS01A1) and the
Bluetooth low energy expansion board
(X-NUCLEO- IDB04A1).
BLUEMICROSYSTEM1 is suitable for all
applications and markets, including IoT and
wearables, that need to effectively sense,
process and transmit valuable information
with very low power consumption and high
performance.
