What is Cmsis FreeRTOS?
FreeRTOS is one of the market leading real-time operating systems (RTOS) for embedded microcontrollers. The CMSIS-RTOS2 API enables programmers to create portable application code to be used with different RTOS kernels (for example Keil RTX5).
Is STM32 a RTOS?
FreeRTOS is a free and open source real-time operating system (RTOS) that runs on many popular microcontrollers, including STM32. In 2017, Amazon took control of the FreeRTOS project and now provides regular maintenance and support.
What is Cmsis-RTOS2?
CMSIS-RTOS2 is a generic API that is agnostic of the underlying RTOS kernel. Application programmers call CMSIS-RTOS2 API functions in the user code to ensure maximum portability from one RTOS to another. Middleware using CMSIS-RTOS2 API takes advantages of this approach by avoiding unnecessary porting efforts.
What is RTOS2?
The CMSIS-RTOS2 manages the resources of the microcontroller system and implements the concept of parallel threads that run concurrently. Applications frequently require several concurrent activities. CMSIS-RTOS2 can manage multiple concurrent activities at the time when they are needed.
How do I start RTOS?

What is Cmsis-RTOS RTX?
The CMSIS-RTOS RTX manages the resources of the microcontroller system and implements the concept of parallel threads that run concurrently. There are many advantages of using the CMSIS-RTOS RTX kernel. The CMSIS-RTOS RTX system is scalable and additional threads can be added easily at a later time.
When to use CMSIS-RTOS API when FreeRTOS API?
The CMSIS-RTOS API located in the CMSIS_RTOS_V2 folder generated by CubeMX is a collection of wrapper functions for FreeRTOS API. The CMSIS-RTOS functions are used in the examples shipped with STM32Cube FW package. My question is when one should use CMSIS-RTOS API and when FreeRTOS API? This is almost 100% opinion based answer.
Where is the CMSIS-RTOS function in stm32cubemx?
The CMSIS-RTOS API located in the CMSIS_RTOS_V2 folder generated by CubeMX is a collection of wrapper functions for FreeRTOS API. The CMSIS-RTOS functions are used in the examples shipped with STM32Cube FW package.
How to use FreeRTOS on STM32 v1.x?
Engineers looking for practical knowledge concerning implementation of FreeRTOS with other STM32 ecosystem components (HAL library, STM32CubeMX usage for code generation) You will improve your practical skills related to CMSIS_OS v1.x based application development using FreeRTOS as a base operating system
Which is CMSIS os.h folder contains CMSIS RTOS folder?
This shows version 9.0.0 Inside source I can see CMSIS RTOS folder which contains cmsis os.h and .c A] Is it wrapper on top of base FreeRTOS API so can we use these API’s instead of FreeRTOS core API ? B] Is these API’s are matuared and well tested ? C] Do they have complete functionality implmentation mentioned CMSIS compliant ?
