- Make configuration structure.
struct
rtc_calendar_config config_rtc_calendar;
- Fill the configuration structure with the default driver configuration.
rtc_calendar_get_config_defaults(&config_rtc_calendar);
Note: This should always be performed before using the configuration struct to ensure that all values are initialized to known default settings. - Make time structure for alarm and set with default and desired values.
struct
rtc_calendar_time alarm;
rtc_calendar_get_time_defaults(&alarm);
alarm.year = 2013;
alarm.month = 1;
alarm.day = 1;
alarm.hour = 0;
alarm.minute = 0;
alarm.second = 4;
- Change configurations as desired.
config_rtc_calendar.clock_24h =
true
;
config_rtc_calendar.alarm[0].time = alarm;
config_rtc_calendar.alarm[0].mask = RTC_CALENDAR_ALARM_MASK_YEAR;
- Initialize module.
rtc_calendar_init(&rtc_instance, RTC, &config_rtc_calendar);
- Enable module.
rtc_calendar_enable(&rtc_instance);
