How to use FreeRTOS with STM32 Microcontroller–Example Project

Learn how to use FreeRTOS with STM32 Microcontroller. The real-time operating system like FreeRTOS allows us multitasking on an MCU. We have used most popular STM32 Nucleo board to demonstrate RTOS capabilities. We have used CMSIS-V2 in STM32CubeIDE. Also, we will learn how to create, delete tasks, and change priority of a task.

very nice explanation bro thanks you so much

I carefully followed the instructions for outputting via printf but see no output in SWV ITM Data Console. I am using an STM32F103C8T6. Should I be defining different "#define" addresses?

Hi I have problem about cubeIDE when I build the code its generates error :
../Core/Src/freertos.c:21:10: fatal error: FreeRTOS.h: No such file or directory
21 | #include "FreeRTOS.h"
|
compilation terminated.
make: *** [Core/Src/subdir.mk:40: Core/Src/freertos.o] Error 1
make: *** Waiting for unfinished jobs....
../Core/Src/main.c:21:10: fatal error: cmsis_os.h: No such file or directory
21 | #include "cmsis_os.h"
|
compilation terminated.
make: *** [Core/Src/subdir.mk:40: Core/Src/main.o] Error 1
"make -j8 all" terminated with exit code 2. Build might be incomplete.

01:46:22 Build Failed. 5 errors, 0 warnings. (took 2s.514ms)
these errors occures. I know these errors mean but when I fix the all after that my the other things generates errors I am reallyy mad about that errors. I even couldnt start the freeRtos for 4 months. Do you have any thing to help me about that problems thanx :)

I use Nucleo-F410RB and follow this tutorial, but i dont see anything in SVM IT Console, if i have adjust some configuration? Thank you in advance

When you see non ASCii signs in the SWV ITM Data Console then your SWV Core Clock Value (in the Debug Configuration menu) is wrong. It should be your CPU Clock rate.

Hi! I have a question, did you still have to download and unzip FreeRTOS? or is it already included in stm32cube ide and stm32cubemx

[KunduruRamesh-nb]

in the task2 we are deleting task1 means it is in forloop how many times ist was deleting

[KunduruRamesh-nb]

how it is coming out from the for loop sir

[mofa]

Hi
can multiple functions run just in one task?

[RakeshWasnik-EmbeddedSystems]

why Trace Asynchronous Sw is used? Most nucleo boards come with ST-link serial wire debug

Hello sir, I have a question generally Software engineers need to upgrade skills very fast, technology in IT moves very fast day by day, what about embedded or Vlsi if we learn to some extent is it to upgrade skills like software pace or it have decent amount of time to upskilling the career ? Share ur view thank you sir

[nothingis_impossible]

Please anybody tell me how i can use qemu debugging plugin in this im trying since week please guide me 😭

[Electronics-cj]

Do you have any Idea, How I can use time slicing in FREERTOS

[rajamukherjee]

which data cable to use to connect stm 32 f446re with laptop?

[Harshavardhan]

Brother, I am 2017 batch from ECE Background, can i start my career in VLSI give me suggestion

[DarshanRayate]

hi sir I have messaged you on Facebook regarding stm32 board can you please check it
