void __attribute__((interrupt))
This ISR handles most of the business interacting with the 1-wire bus.
Default definitions of C compiler quirk work-arounds.
void clock_init(void)
Initialize the clock library.
CCIF clock_time_t clock_time(void)
Get the current clock time.
clock_time_t etimer_next_expiration_time(void)
Get next event timer expiration time.
void etimer_request_poll(void)
Make the event timer aware that the clock has changed.
CCIF unsigned long clock_seconds(void)
Get the current value of the platform seconds.
int etimer_pending(void)
Check if there are any non-expired event timers.
void clock_delay(unsigned int delay)
Obsolete delay function but we implement it here since some code still uses it.
#define CLOCK_SECOND
A second, measured in system clock time.
