製品概要
概要
The FP-SNS-DATALOG1 function pack implements High Speed Datalog application for 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 ISM330DHCX Machine Learning Core unit and reading its output.
Sensor data can be stored onto a micro SD 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 JSON file as well as starting and controlling data acquisition. Commands can be sent from a host via command line interface.
The application can be controlled via Bluetooth using the STBLESensor app (available for Android and under development for iOS) which lets you manage the board and sensor configurations, start/stop data acquisition on SD card, control data labelling 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 3.7.
