How to get the precise time of the consumption function by using SYSTICK timer?
Posted on August 21, 2014 at 02:53As far as I knew, SYSTICK Timer is a 24-bit down counter. For now, I need to know the precise consumption time for the memcpy function. Suppose I set SysTick->RELOAD = 511, it will turn out two cases as the followin...
