X-CUBE-AZRTOS-L5 (Azure® RTOS STM32Cube Expansion Package) provides a full integration of Microsoft® Azure® RTOS in the STM32Cube environment for the STM32L5 Series of microcontrollers. Ready-to-run applicative examples provided for the NUCLEO‑L552ZE‑Q and STM32L562E‑DK Evaluation boards, along with a full compatibility with STM32CubeMX and STM32CubeIDE, ensure that X-CUBE-AZRTOS-L5 drastically reduces the learning curve and provides a smooth application development experience with Azure® RTOS and STM32L5 Series microcontrollers.
The scope of this Expansion Package covers the following Azure® RTOS middleware: RTOS (ThreadX), USB 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 STM32L5 users.
X-CUBE-AZRTOS-L5 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-L5 Expansion Package, which therefore does not support native connectivity to the Azure® IoT Hub.
