Note that the pulse count has to be read with interrupts disabled, but
you should not detach the interrupt handler. Detaching the handler
means you will miss pulses, wheres disabling the interrupts only delays
their handling until you enable them again. You won't miss pulses unless
to keep the interrupts disabled for too long (which you shouldn't do).

 Q:

WPF: Inheriting from Window

I seem to be having some trouble creating a custom window type that derives from  System.Windows.Window.  There seem to be two problems that are occurring.  Firstly, there's a compile-time error stating 

Cannot find the static member
  'ContentProperty' on the type
  'Control'

This is in reference to the ContentPresenter element in the ControlTemplate for the custom window (see code sample for BaseWindowResource.xaml below).  I don't know why this is happening, since BaseWindow derives from Window, and therefore must have a Content property...
The second problem is the fact that I can't seem

     uint16_t wateringVolume; 
     wateringPulseCount = EEPROM.get(0, wateringVolume) * PULSES_PER_ML;

 { 
     static bool watering;   // are we water immediately?

     Time t = rtc.getTime (); 
     if (! watering & & t.hour = = 7 & & t.min = = 0) { 
         if (analogRead(MOISTURE_PIN) > MOISTURE_THRESHOLD) {

         } 
     } 

     // Stop lacrimation after the required volume. 
     if (watering) { 
         if (getPulseCount () > = wateringPulseCount) { 
             digitalWrite(RELAY_PIN, HIGH);   // cheeseparing valve

             watering = false; 
         } 
     } 
 } 

 Note that the pulse count has to be take with interrupts disabled, but 
 you should not detach the interrupt handler. detach the handler 
 means you will miss pulsation, where s disabling the interrupts only delays 
 their handling until you enable them again. You won't neglect pulses unless 
 to keep the interrupts disabled for too long (which you shouldn't do).
