Embedded software samples for BlueCoin: data streaming via USB and BLE, logging on SD card, gesture recognition, audio acquisition and playback

The STSW-BCNKT01 firmware package for BlueCoin Starter Kit provides sample projects for the development of custom applications. Built on STM32Cube software technology, it includes all the low level drivers to manage the on-board devices and system-level interfaces.

The package comes with the DataLog, AudioLoop, BLE_SampleApp and Gesture Recognition applications. The DataLog application features sensor raw data streaming via USB (Virtual COM Port class) and sensor data storage on SD card. The BLE_SampleApp provides a sample Bluetooth low energy configuration that enables BlueCoin to stream environmental sensor data; it is compatible with the ST BlueMS app available for Android and iOS. The Gesture Recognition application exploits the Time-of-Flight ranging sensors to detect the distance of a target object, and some simple gestures such as directional swipe and tap.

Key Features

  • Complete firmware suite to build applications on BlueCoin development kit using:
    • STM32F446 high-performance microcontroller
    • motion sensors
    • microphone array
    • pressure sensor
    • temperature sensor
    • proximity sensors
  • Based on STM32Cube, the consistent and complete embedded software for STM32 that maximizes portability between all STM32 series and frees the user from dependency issues.
  • A DataLog application which allows the real-time transmission of all sensor data to a PC via serial port or to save/log sensor data to file on an SD card
  • An AudioLoop application which sends audio signals acquired by the microphones to USB (Audio IN Class) and to an on-board DAC via I²S interface.
  • A GestureRecognition application to configure Time-of-Flight ranging sensors and gesture detection middleware.
  • A BLE_SampleApp which provides an example of Bluetooth low energy configuration
  • A third party FAT file system middleware for small embedded systems
  • Freely available in source code from ST web site
