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 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).
    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.
    For audio sample projects, refer to X-CUBE-MEMSMIC1 software package.
