I'm not aware of why writing the prescaler wouldn't work, but generally I modulate the Period or Pulse in an Update interrupt. Both Prescaler and Period are written as N-1 values, the prescaler is always limited to 16-bit.

Minimum requirements:

State clearly the model of STM32 being used from the outset

Provide complete compilable code, this can be a subset of the whole, but it needs to compile in a stand alone form. Code should include all defines, as well as clock and pin initialization.

Use the syntax high-lighter to post code.

If the code runs hundreds on lines, attach the C file as an attachment to the post.

If the code is spread across multiple files ZIP all files together and post a single file.

Failure to do these things will likely result in your post being ignored.

Thanks for your replay. I'll surely remember your suggestions in future posts. The code is working now. I've re-generated the whole code from STM32CubeMX with timer settings corrected after full deletion of rthe faulty project. Now everything is working fine. Thanks again.
