Hi Richard, Thank you so much for the detailed reply.

Here are few doubts:

  1. How the timers of microseconds was achieved in software timers?

  2. In the documentation, I read of content of software timer as follows:
    “Software timers are implemented by, and are under the control of, the FreeRTOS kernel. They do not require hardware support, and are not related to hardware timers or hardware counters.”
    But while generating the code via stmcubemx, we choosed the timebase source in sys tab of “System core” as “TMR 6” instead of “systick”. Here software timer actually uses one of the hardware timer right?

Which of timebase source used by Tick interrupt generally?
