Hello, I have a problem with the timers when I want to change the period. After I call the function for changing the period, the timer is active but never expiring. im using latest version of FreeRTOS. Thanks in advance!

I presume the timer is expiring normally before you change the period. What is the period before the change, and what are you changing the period to? Please show the function call you are making to change the period.
