#9 CANfestival timer

[Arathi]

I am integrating CANfestival stack on STM32 controller.
My system clock is 96Mhz and timer i have configured for 5usecs
//#define MS_TO_TIMEVAL(ms) ((ms)200)
//#define US_TO_TIMEVAL(us) ((us)1/5)
so with above setting and my heartbeat producer value set to 2sec. it is not working as expected.
heartbeat is produced every ~15ms.
Can someone please help me in getting timer setting proper so that HB works as expeted?
Thanks
