Product overview


The FP-SNS-DATALOG1 function pack implements High Speed Datalog application for STEVAL-MKSBOX1V1, STEVAL-STWINKT1, and STEVAL-STWINKT1B. It provides a comprehensive solution to save data from any combination of sensors and microphones configured up to the maximum sampling rate.

The application also allows configuring LSM6DSOX (available on STEVAL-MKSBOX1V1) and ISM330DHCX (available on STEVAL-STWINKT1 and STEVAL-STWINKT1B) Machine Learning Core unit and reading its output.

Sensor data can be stored onto a microSD™ card (Secure Digital High Capacity - SDHC) formatted with the FAT32 file system, or streamed to a PC via USB (WinUSB class) using the companion host software (cli_example) provided for Windows and Linux.

The FP-SNS-DATALOG1 allows configuring the board via a JSON file as well as starting and controlling data acquisition. Commands can be sent from a host via the command line interface.

The application can be controlled via Bluetooth using the STBLESensClassic app (for both Android and iOS - v4.17 and above) which lets you manage the board and sensor configurations, start/stop data acquisition on an SD card, control data labeling and display the output of the Machine Learning Core.

To read sensor data acquired using FP-SNS-DATALOG1, easy-to-use scripts in Python and MATLAB® are provided within the software package. The scripts have been successfully tested with MATLAB® v2019a and Python 3.10.

The software is available also on GitHub, where the users can signal bugs and propose new ideas through [Issues] and [Pull Requests] tabs.
