Sales Briefcase
  • The STSW-STWINKT01 firmware package for the SensorTile Wireless Industrial Node (STWIN) development kit provides sample projects that you can use to develop custom predictive maintenance, smart industry, IoT and remote monitoring applications. The package is based on our STM32Cube software technology, and includes all the low level drivers to manage the on-board devices and system-level interfaces.

    The package features two projects that demonstrate data logging functionality. One involves streaming data via the USB Virtual COM Port class, which you can subsequently display directly on a PC terminal, and the other is for high speed data storage at maximum sensor sampling rates. In the second case, sensor data can be either stored on micro SD card or can be streamed via USB (WinUSB class).
    There are also three projects regarding audio. The OnboardMics application streams audio signals from both the on-board analog and digital microphones via USB, so you can record and process them on a host PC. The MicArrayCoupon application instead requires the STEVAL-STWINMAV1 microphone array expansion board (not included in the kit), from which the application can simultaneously acquire up to four external microphone audio signals through a USB interface.
    The UltrasoundFFT example calculates the FFT of the on-board analog microphone signal and streams the result to a PC GUI via USB. The microphone sampling rate is set by default to 192 kHz whereas the microphone bandwidth is up to 80 kHz.
    Other two projects demonstrate wireless connectivity using Bluetooth and Wi-Fi. The Bluetooth project allows you to stream environmental sensor data via the Bluetooth Low Energy (BLE) protocol, and is compatible with our freely available ST BLE Sensor app on Android and iOS stores, so you can read and manipulate the data from your mobile device. The Wi-Fi project requires the STEVAL-STWINWFV1 Wi-Fi expansion board (not included in the kit) to implement basic network functionality including pinging a remote station, connecting to a TLS secure server, sending data to an echo server and verifying returned data, and running a server that a remote client can connect to.
