Description
X-CUBE-AZRTOS-G4 (Azure
®
RTOS STM32Cube Expansion Package) provides a full integration of Microsoft
®
Azure
®
RTOS in the STM32Cube environment for the STM32G4 series of microcontrollers. Ready-to-run
applicative examples provided for the
NUCLEO-G474RE and STM32G474E-EVAL Evaluation boards, along with
a full compatibility with STM32CubeMX and STM32CubeIDE, ensure that X-CUBE-AZRTOS-G4 drastically
reduces the learning curve and provides a smooth application development experience with
Azure
®
RTOS and
STM32G4 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).
Azure
®
RTOS FileX, Azure
®
RTOS LevelX, and Azure
®
RTOS USBX are also available to run in bare-metal
mode without the Azure
®
RTOS ThreadX kernel.
FreeRTOS
™
and CMSIS RTOS V2 adaptation layers are included and demonstrated, making it easy and quick to
migrate from FreeRTOS
™
or another RTOS to Azure
®
RTOS ThreadX for STM32G4 users.
X-CUBE-AZRTOS-G4 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-G4 Expansion Package, which therefore does not
support native connectivity to the Azure
®
IoT Hub.
