Description

FP-SNS-ALLMEMS2 is an STM32Cube function pack which lets you connect your

IoT node to a smartphone via BLE and use a suitable Android™ or iOS™ application,

like the STBLESensor app, to view real-time environmental and motion sensor data,

digital microphone and battery levels.

It provides features similar to the FP-SNS-ALLMEMS1 function pack, but with a

different implementation for ultra-low power consumption.

The package also enables advanced functions such as voice communication over

BLE, sound source localization and acoustic beam forming using inputs from multiple

microphones, as well as sensor data fusion and accelerometer-based real-time

activity recognition, audio data logging and MEMS sensor data logging on SD card.

This package, together with the suggested combination of STM32 and ST devices,

can be used to develop specific wearable applications or smart things applications in

general, where ultra-low power consumption is a key requirement.

The software runs on the STM32 microcontroller and includes all the necessary

drivers to recognize the devices on the STM32 Nucleo development board and

expansion boards, as well as on the STEVAL-BCNKT01V1, STEVAL-MKSBOX1V1

and STEVAL-STLKT01V1 evaluation boards.

1 Detailed description

1.1 What can you do with STM32Cube function packs?

STM32Cube function packs leverage the modularity and interoperability of STM32 Nucleo and X-NUCLEO

boards together with STM32Cube and X-CUBE software to create function examples for some of the most

common use cases of dif

ferent application technologies.

These software function packs are designed to exploit the underlying STM32 ODE

hardware and software

components as much as possible to best satisfy the requirements of final user applications.

Moreover, function packs may include additional libraries and frameworks that are not present in the original X-

CUBE packages, thus enabling new functionalities allowing real and usable system for developers.

1.2 What is STM32Cube?

STM32Cube is a combination of a full set of PC software tools and embedded software blocks running on STM32

microcontrollers and microprocessors:

• STM32CubeMX configuration tool for any STM32 device; it generates initialization C code for Cortex-M

cores and the Linux device tree source for Cortex-A cores

• STM32CubeIDE integrated development environment based on open-source solutions like Eclipse or the

GNU C/C++ toolchain, including compilation reporting features and advanced debug features

• STM32CubeProgrammer programming tool that provides an easy-to-use and ef

ficient environment for

reading, writing and verifying devices and external memories via a wide variety of available communication

media (JT

AG, SWD, UART, USB DFU, I2C, SPI, CAN, etc.)

• STM32CubeMonitor family of tools (STM32CubeMonRF, STM32CubeMonUCPD, STM32CubeMonPwr) to

help developers customize their applications in real-time

• STM32Cube MCU and MPU packages specific to each STM32 series with drivers (HAL, low-layer, etc.),

middleware, and lots of example code used in a wide variety of real-world use cases

• STM32Cube expansion packages for application-oriented solutions

1.3 How does this STM32Cube function pack complement STM32Cube?

This software is based on the STM32CubeHAL. It extends STM32Cube

by providing a board support package

(BSP) for the BLE sensor expansion board and middleware components for communication with other BLE

devices, for sensor data fusion, real-time audio library

, voice communication over BLE and SD card data logging.

The package contains audio libraries (AcousticBF, AcousticSL and BlueVoiceADPCM) and motion sensor libraries

(MotionFX, MotionAR, MotionCP and MotionGR) useful for sensing applications based on BLE communication.
