Functions
void	check_clock_and_update (void)
void	check_periodic_task (void)
void	delay_ticks (uint16_t delay)
	Performs a busy loop delay of delay system ticks. The watchdog is continuously refreshed during the delay. More...
void	rtc_alarm_task (void)
void	rtc_cancel_periodic_task (void)
	Cancels the execution of the periodic task setting to 0 the periodic task timer. More...
int	rtc_config (void)
	Configures and initializes the RTC module, with the defualt settings. Its automatically called by sys_hw_init() More...
void	rtc_config_fast (void)
void	rtc_config_slow (void)
int	rtc_get_date (tm_t *now)
	Reads the RTC time/date and saves it in now. More...
uint32_t	rtc_get_ms_uptime (void)
	Returns the miliseconds counter, number of ms the system has been running without interruption (downtime) More...
uint32_t	rtc_get_uptime (void)
	Returns the second counter, number of seconds the system has been running without interruption (downtime) More...
uint8_t	rtc_is_slow (void)
void	rtc_isr (void)
	RTC interrupt service routine. More...
void	rtc_periodic_task (void)
	Function called when the periodic timer expires. The periodic timer is rearmed automatically by the firmware. More...
int	rtc_set_alarm (tm_t newalarm)
	Programs the alarm with newalarm time values. More...
int	rtc_set_date (tm_t newdate)
	Sets date as RTC date. More...
int	rtc_set_periodic_task_period (uint32_t period)
	Configures the period (expressed as number of system ticks) of execution of the periodic task. A call to this function resets/restarts the periodic task timer. More...
void	rtc_set_timeout (uint16_t timeout)
	Programs the timeout variable, decremented each system tick. More...
bool_t	rtc_timeout_expired (void)
	Returns a 1 if the programmed timeout expired. The timeout is programmed with rtc_set_timeout() More...
void	update_date (void)
