X-CUBE-AZRTOS-L4 (Azure® RTOS STM32Cube Expansion Package) provides a full integration of Microsoft® Azure® RTOS in the STM32Cube environment for the STM32L4 Series and STM32L4+ Series of microcontrollers. Ready-to-run applicative examples provided for the NUCLEO-L4R5ZI and 32L4R9IDISCOVERY Evaluation boards, along with a full compatibility with STM32CubeMX and STM32CubeIDE, ensure that X-CUBE-AZRTOS-L4 drastically reduces the learning curve and provides a smooth application development experience with Azure® RTOS, and STM32L4 Series and STM32L4+ Series microcontrollers.
The scope of this Expansion Package covers the following Azure® RTOS middleware: RTOS (ThreadX), USB Host and Device (USBX), and file system including the support for NOR and NAND Flash memories (FileX and LevelX).
A FreeRTOS™ adaptation layer is included and demonstrated, making it easy and quick to migrate from FreeRTOS™ to Azure® RTOS ThreadX for STM32L4 and STM32L4+ users.
X-CUBE-AZRTOS-L4 is only an STM32Cube integration of middleware stacks from Microsoft® Azure® RTOS. Neither the Azure SDK for Embedded C nor the Azure IoT Middleware for Azure RTOS, available from www.github.com/azure, are part of the X-CUBE-AZRTOS-L4 Expansion Package, which therefore does not support native connectivity to the Azure® IoT Hub.
