The following code sample measures the time of the for-cycle in microseconds (requires floating point library):
MAIN.C
void main(void)
{
unsigned int i, time;
float one_loop_us;
FC81_Reset(); /* reset the counter */
for (i = 0; i < 60000; ++i); /* for-cycle */
/* get measured time of whole for-cycle */
if(FC81_GetTimeUS(&time) == ERR_OK) {
/* average time of one loop */
one_loop_us = time / 60000.0;
}
}
