X-CUBE-AVS is an expansion package for the STM32Cube software platform from STMicroelectronics. It contains ready-to-use libraries and open routines that accelerate porting the AVS SDK (Software Development Kit) to the microcontroller.
The newly launched X-CUBE-AVS software package enables Amazon’s Alexa Voice Service (AVS) to run on STM32 microcontrollers. It allows simple connected objects such as smart appliances, home-automation devices, and office products to support advanced conversational user interfaces with Cloud-based intelligence like automatic speech recognition and natural-language understanding.
X-CUBE-AVS is the first such package to cater specifically for microcontrollers. In general, AVS development usually targets more power-hungry and expensive microprocessors, X-CUBE-AVS makes Alexa technology accessible to a wider spectrum of developers and projects.
The software handles low-layer communication and connection to AVS servers. It provides application-specific services, and encapsulates the AVS protocol to ease application implementation.
X-CUBE-AVS comes with a demonstration example for the STM32F769 Discovery Kit, which shows how to connect a simple smart-speaker to AVS, leveraging the board-configuration interface included in the software. It can be used with other STM32F7 microcontrollers, or any STM32 device with adequate CPU performance and memory to run the AVS SDK.
It is now available to download, free of charge.
