Stmicroelectronics Stm32 Software Package For Simple Iot Products With Amazon's Alexa Technology

April  2, 2018, China - STMicroelectronics' X-Cube-AVS software package  enables Amazon's Alexa Voice Service (AVS) to run on STM32*  microcontrollers, enabling cloud intelligence (automatic speech  recognition and Advanced conversational user  interfaces for natural language understanding appear on simple IoT  devices such as smart home appliances, home automation devices, and  office equipment.

As  an extension to the STM32Cube software platform, the X-CUBE-AVS  contains a directly available firmware library and open routines, which  helps to quickly port the AVS SDK (software development kit) to the  microcontroller. In  addition, the software package also integrates application code  examples, eliminating the need for developers to develop complex  software layers needed for embedded devices to run AVS. AVS development tools are usually designed for high power consumption  and high price microprocessors, and X-CUBE-AVS is the first dedicated  software package for similar microcontrollers, allowing more developers  and projects to use Alexa technology.

The  software handles the connection between the IoT device and the bottom  layer of the AVS server, provides dedicated services, and encapsulates  the AVS protocol to simplify the implementation of the application. The  connection management feature includes a permanent token mechanism that  can directly restore disconnected connections without the need for  repeated user authentication procedures. The software package also provides durability testing software tools  that can simulate events such as network disconnections to simplify the  robustness testing and verification of user applications.

The  X-CUBE-AVS contains a demonstration sample of the STM32F769 discovery  kit (order code: 32F769IDISCOVERY) that demonstrates how to use the  board configuration interface included in the software to connect a  simple smart speaker to the AVS. The  X-CUBE-AVS can be used with the STM32F7 microcontroller or any STM32  product with CPU performance and memory that meets the AVS SDK  requirements. The X-CUBE-AVS software can now be downloaded for free from http://www.st.com/x-cube-avs.
