With Azure RTOS complementing the extensive STM32Cube ecosystem providing free development tools, software bricks, and software expansion packages, STM32 users can also leverage the rich services of Azure RTOS, which meet the needs of tiny, smart, connected devices.
X-CUBE-AZRTOS-F7 (Azure RTOS Software Expansion for STM32Cube) provides a full integration of Microsoft Azure RTOS in the STM32Cube environment for the STM32F7 series of microcontrollers. Ready-to-run applicative examples are also provided for the STM32F767ZI-Nucleo, STM32F735G-DK, STM32F747I-DK and STM32F743I-EVAL evaluation boards, thus reducing the learning curve and ensuring a smooth application development experience with Azure RTOS and STM32F7 MCUs.
The scope of this package covers the following Azure RTOS middleware: RTOS (ThreadX), USB Device and Host (USBX), File System including NOR/NAND memories support (FileX and LevelX) and Networking including Ethernet and WiFi media (NetXDuo).
Azure RTOS is a professional grade, highly reliable and market proven Middleware suite:
- Integrated and full featured RTOS. Learn more ThreadX.
- Industrial grade networking stack: optimized for performance coming with many IoT protocols. Learn more Netx Duo
- Advanced FS/FTL: fully featured to support NAND/NOR Flash memories. Learn more FileX and LevelX
- USB Host and Device stacks coming with multiple classes. Learn more USBX
- Safety pre-certifications (from Microsoft): IEC 61508 SIL4, IEC 62304 Class C and ISO 26262 ASIL D
- Security pre-certifications (from Microsoft): EAL4+ for TLS/DTLS, FIPS 140-2 for SW crypto lib
- STM32 granted production license: here
- USBX, FileX and NetXDuo building require ThreadX as they are based on RTOS model.
- USBX Host MSC requires FileX Middleware usage
- USBX Device ECM/RNDIS classes require NetXDuo usage
