The mutex should protect the "counter" variable in this example
And every time before using "counter" mutex also is used
The print function works using this:

void SWO_PrintChar(char const c, uint8_t const portNo)

Hello, thanks for support

I kind of fixed timer's callback
And added a mutex to the critical section as well

Everything works, but since there was a comment indicating the erroneous use of critical sections, I decided to attach the code again

If it's not difficult, please take a look: is ...

Did I do something wrong?
What other violations are there?

Hello
thank you so much for your help

(my question arose when I was experimenting with the library's capabilities)
That code I divided into 2 parts

This example demonstrates the operation of critical code blocks in threads

#include "ch.h"
#include "hal.h"
#include "rt_test_root.h ...

I'm really trying to understand how to use interruptions and locked code blocks
