UWP C# Windows 10 IoT Alarm Clock

问题:

I am trying to write an alarm clock app that can set multiple alarms to trigger output pin on Raspberry Pi. Is there any reference project out there I can refer to? or does windows 10 alarm & clock app reference code is available for reference?

I want to find out how to save the individual alarm and display them. do i use a DispatchTimer to monitor the all the alarms set? Thanks.

Updated: The alarm setting intended look like this.

portion of my code to create the appointment is as below. But i dont seem to be able to see any appoint created as the UWP appointment Sample.

 private void Save_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
    {
        var appointment = new Windows.ApplicationModel.Appointments.Appointment();
        var recurrence = new Windows.ApplicationModel.Appointments.AppointmentRecurrence();

        var scheduleTime = TimePicker.Time;
        var timeZoneOffset = TimeZoneInfo.Local.GetUtcOffset(DateTime.Now);
        var startTime = new DateTimeOffset(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, scheduleTime.Hours, scheduleTime.Minutes, 0, timeZoneOffset);
        appointment.StartTime = startTime;

        appointment.Duration = TimeSpan.FromMinutes(5);

        if(dailyAlarm.IsOn == true)
        {
            recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Daily;
        } else
        {
            if (setMonday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Monday; }
            if (setTuesday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Tuesday; }
            if (setWednesday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Wednesday; }
            if (setThursday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Thursday; }
            if (setFriday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Friday; }
            if (setSaturdayday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Saturday; }
            if (setSunday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Sunday; }
        }
    }
