Presentation Notes

For STM32 families being available in 2021 or later, for example first one being STM32U5, Azure RTOS will be natively integrated in the STM32Cube MCU package. These families will not have dedicated expansion package. Customers will benefit of native CubeMX or CubeIDE support to start new project based on Azure RTOS middlewares. Of course, those who still prefer our legacy middlewares for new STM32s, we will have them available on our Github with set of different examples. First MCU package with Azure RTOS is expected together with mass-market announcement of STM32U5 product, that is planned in Q3 2021.

Presentation Notes

To let you get started quickly and effectively and to understand different applications, we have prepared set of examples for each Azure RTOS component. These are split in 4 different sections: For ThreadX we prepared simple examples for dynamic thread creation, synchronization and thread communication using message queues. Customers currently using FreeRTOS operating system or CMSIS-OS layer can benefit of examples that are compatible with their previous application syntax Then for USBX, examples are split between host and device modes. Standard set of classes is included, including multi-class configuration, like for example HID and CDC dual-class for USB device TCP/IP stack ThreadX includes TCP and UPD examples, each of them in server or client mode. For the application, we include HTTP server, MQTT client and SNTP client modes Lastly, FileX comes with set of different examples for SD card, NAND or NOR memories. Or, if you prefer to Start with CUbeMX or CubeIDE without example, it is made possible thanks to our Expansion package graphical configuration capability

Presentation Notes

You may have wondered who to move forward if you have you application based on FreeRTOS or CMSIS-OS while ST is moving to Azure RTOS instead. Azure RTOS natively comes with FreeRTOS application layer. This means that customers using FreeRTOS application functions can now seamlessly transfer project to ThreadX and still keep application API. Furthermore, customers benefit of high performant and low-memory footprint operating system with industry leading position and set of industry certifications. On the other side, if your application is today based on CMSIS-OS application syntax, ST is delivering Azure RTOS ThreadX port to seamlessly migrate to ThreadX and still keep CMSIS-OS API functions. This is an unique feature available only for STM32 customers.

Presentation Notes

CubeIDE has been recently updated to version 1.6. This version is necessary to use Azure RTOS expansion pack and when working with Azure-RTOS enabled application, it comes with operating system aware debugging for ThreadX. CubeIDE comes with integrated functionality of CubeMX, that let’s you have single tool for code configuration and project development An eclipse-based IDE features advanced code development GCC compiler covers your compilation demand and CubeProgrammer let’s you flash your MCU to be able to effectively debug it. Lastly, for Azure RTOS we have added OS awareness. This features let’s you browsing threads and seeing their current state. Furthermore, you can see a list of other OS services, for example semaphores, mutexes, memory pools or timers. Stay tunes for next versions where we will integrate more operating system aware debugging features.
