Hi all forumers !! 

 

I'm totally new to fpgas and I'm trying to get my best !!  

 

But now I really need some suggestions.. I'm implementing a routine in C with quartus that uses a timer but I cannot find how to get it... I need to implement something like that: 

 

#include<time.h> ..... some code here ..... time_t start,now; time(&start); seconds = 0; while seconds < 1 { ... do something... time(&now); seconds=(uint8_t) difftime(now,start); }  

 

by the way it seems not working... i always get seconds==0. 

 

There is a better way to get it works ?? 

 

Thank you for your support !! 

 

Have a nice day !

Solved it. 

 

It was sufficient to add and configure "interval timer" in my qsys. I have called it sys_clck_timer. Than, in eclipse, I have added the sys_clck_timer in the bsp editor of my project.
