Just found out about CubeMX, was doing it the hard way before this..... I have not found a way in MX to create a complete thread based program.

I cannot find anything in the code generation which allows for me to easily, being the operative word, create threads from the generated code. I have not been able to find any examples either to this nature.

What is the best way to go from a standard "main" loop to a thread based generated program? Are there any examples? Every time I create a thread I get an unhappy compiler. There is a secret somewhere on how to create a true thread based program, isn't there?

In CubeMX, when you configure your project, choose Middleware FreeRTOS and a CMSIS interface (both will do, V2 is newer). Depending on how deep you want to dive, you can create tasks (=threads) etc. in CubeMX or in the code. You find the docs here: https://www.keil.com/pack/doc/CMSIS/RTOS2/html/group__CMSIS__RTOS.html

Hi @BEppe.1 ,

Welcome to the community and thanks for your feedback,

You can find plenty of FreeRTOS Examples under Example Selector in CubeMX, some of which are available for CubeMX (Please refer to the attachment). And as @KnarfB mentioned, when you configure your project you can find FreeRTOS under Middleware.

Since you just started using CubeMX, I advise you to watch our tutorial videos, you can access to them easily from Help menu/Tutorial videos in CubeMX.

Thanks that was helpful. Only there are no examples for my board. B-L475E-IOT01A2. I put some code together using different video's, but the "PWM Start" won't start the PWM. Here is the important parts the init and run code. Any suggestions would be appreciated. I have my scope on the correct pin I programmed, I know as I have an Excel sheet with all the pins available from the board matched with the pins used.

Suggestions?
