void timer1_init

(

void

)

initialize timer1

Set up timer1 for continous counting.

The prescaler is set to 1/256. Therefore the elapsed time t can be calculated in the following way:

{
  power_timer1_enable ();
  TCCR1A = 0;
  TCCR1B = _BV(CS12); /* prescaler 1/256 */
  TIMSK1 = 0; /* no INT generation */
}
