Implement how to get the current tick (of the cpu) or create own tick with a defined time interval.

One possibility would be to use a timer interrupt.

solution proposal:


#include <time.h>

int main(){

   clock_t start, end;
   int32_t cpu_tick = 0;

   if(cpu_tick== 0){
      start = clock();
      for(int i=0; i<100000; i++){
         int a = i*2 + i %2323;
      }
      end = clock();
      cpu_tick = ((int32_t) (end-start)) / F_CPU;


   }

   //Our code

}

Example calculation for nextTick:

clock() + F_CPU * 0.2

The nextTick should then be in 0.2s
