Pseudo-code for Dodge Button module
**************************************************************************************

InitializeButtonDebounce
//Takes a priority number, returns True. 
	Initialize the MyPriority variable with the passed in parameter.
	Initialize the port line to monitor the buttons - using PD0 for left button, PD1 for right button
	Sample the button port pins and use them to initialize LastButtonState_L and LastButtonState_R
	Set CurrentState to be DEBOUNCING
	Start debounce timer (timer posts to ButtonDebounceSM)
End of InitializeButtonDebounce

PostButtonService
	Takes an event and posts to service 
End of PostBeamBreak

CheckButtonEvents
//Takes no parameters, returns True if an event was posted
	local RetrunVal = False, CurrentButtonState

	Set CurrentButtonState_L to state read from port pin PD0
	Set CurrentButtonState_R to state read from port pin PD1

	If the state of the port line PD0 has changed
		If the current state of the port line is LO
			PostEvent BUTTON_PRESSED with parameter 'L'
		Set ReturnVal = True
	Endif
	If the state of the port line PD1 has changed
		If the current state of the port line is LO
			PostEvent BUTTON_PRESSED with parameter 'R'
		Set ReturnVal = True
	Endif
	Set LastButtonState_L to CurrentButtonState_L
	Set LastButtonState_R to CurrentButtonState_R
	Return ReturnVal
End of CheckButtonEvents

RunButtonDebounce
//Takes an input event, returns a blank event
//The EventType field of the input Event will be one of: ButtonPressed, or ES_TIMEOUT.

	Based on the state of the CurrentState variable choose one of the following blocks of code:
		CurrentState is Debouncing
			If ThisEvent is ES_TIMEOUT and 
				Set CurrentState to Ready2Sample
			Endif 
		End Debouncing block

		CurrentState is Ready2Sample
			If ThisEvent is BUTTON_PRESSED
				Initialize BUTTON_TIMER with Debounce Time
				Set CurrentState to Debouncing
				Post Event to PostDodgeRegister
			Endif 
		End Ready2Sample block
	Set CurrentState to NextState
	Return ES_NO_EVENT
