增加闹钟

void alarm_delete(u8 index);
删除闹钟

void rtc_update_time_api(struct sys_time *time)
更新时间api(更新了时间必须调用该接口)

u8 alarm_active_flag_get(void);
闹钟到达的标志

u8 alarm_get_info(PT_ALARM p, u8 index)
获取闹钟信息

u8 alarm_get_active_index(void);
获取当前激活使能的闹钟(可以理解为下一个会响的闹钟)


u8 alarm_get_total(void)
获取当前已经设备的闹钟数(包括关闭的闹钟)


void rtc_calculate_next_few_day(struct sys_time *data_time,u8 days)
获取今天星期几


void alarm_name_set(u8 *p, u8 index, u8 len)
设置闹钟名字
