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.
stm32-usbx-examples provides a full integration of Microsoft Azure RTOS in the STM32Cube environment for the STM32Hxx series of microcontrollers. Ready-to-run applicative examples are also provided for STM32xx, thus reducing the learning curve and ensuring a smooth application development experience with Azure RTOS and STM32 MCUs.
The scope of this package covers the following Azure RTOS middleware: USB Device and Host (USBX) with examples shows how to develop USB Device and host applications.
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 and FileX can be used in standalone mode without RTOS.
- USBX Host MSC requires FileX Middleware usage
- USBX Device ECM/RNDIS classes require NetXDuo usage
One of the following toolchains:
- IAR Embedded Workbench for ARM (EWARM) toolchain 8.50.9 + ST-LINKV3
- STM32CubeIDE V1.13.1 + ST-LINKV3
- RealView Microcontroller Development Kit (MDK-ARM) toolchain V5.37 + ST-LINKV3
The STMicroelectronics GitHub X-CUBE-AZRTOS repository consists of the following repositories:
- Drivers: contains STM32xx CMSIS, HAL and BSP drivers
- Middlewares: contains ThreadX, NetX Duo, FileX, LevelX and USBX stacks including porting on STM32 hardware
- Projects: provides ready-to-run applicative examples for Azure RTOS on the supported boards. Projects are structured as follows:
