Best resources to learn FreeRTOS STM32CubeMX & TrueStudio

[Michael Uman]

Hello,

I'm rather new at MCU programming but have been a SWE for 20+ years working in low-level Linux (libraries and device drivers) and I understand the basics of multi-threaded programming. I have several STM32 eval boards including P-Nucleo-STM32WB55 and Nucleo-32 STM32466RE and would like to delve into FreeRTOS middleware.

I have managed to create a microcode which flashes the LED every second running in a thread but I still feel like I'm missing quite a bit. I have been `googling` this topic for the last 2 days and have not found anything specific to the STM32CubeMX/TrueStudio toolchain.

I figured the best way to learn would be to ask those who know. That is why I came here to the ST forum for advice.

Thank you,

My suggestion is to not use CubeMX flawed bloatware and use FreeRTOS directly. First get it running like in these examples:

http://www.pezzino.ch/freertos-hello-world/

And from there official FreeRTOS documentation is the help:

Hello Piranha,

Thank you very much for your prompt reply.

I had a quick look at the material you suggested and it seems helpful. In my short experience it seems that STMCubeMX adds a layer CMSIS (Cortex Micro-controller Software Interface Standard) to the project which provides an alternate API for thread creation and manipulation. I appreciate your link to the official FreeRTOS documentation.

Thank you,

And some links explaining what is CMSIS and in particular CMSIS-RTOS:

Enjoy the reading.

Hello Pavel,

Thank you for the links to the CMSIS documentation. I have started looking at them and find them very helpful to understand the FreeRTOS API.

Have a good day!
