Project Name: LEDButton_Polled

Project Type:
	ADSP-BF533 [ ]
	ADSP-BF537 [X]
	ADSP-BF561 [ ]
	
Hardware Used:
	EZ-Kit LEDs and Buttons 
	
System Services Components Used:
	DMA Manager                         [ ]   Deferred Callback Manager   [ ]
	Interrupt Manager                   [ ]   Timer Module                [ ]
	Power Management Module             [ ]   Flag Module                 [X]
	External Bus Interface Unit Module  [ ]   Port Module                 [ ]
	
Example Overview:
	This is a demo program which show how to use the Flag service to access LEDs
	and push buttons. 

	The LED's except led 6 and led 7 (power) are turned off when you start the program.
 
	This example uses the first three switches and the first 2 LEDs.
	 
	
	SW13 (first button  or PB-1)  - toggles LED1 on/off
	SW12 (second button or PB-2)  - toggles LED2 on/off
	
	If you press button SW11 (or PB-3) the program terminates

	This example uses polling to check if a button has been pressed using the flag service.
	If a button has been pressed the appropriate action is taken to toggle the corresponding
	LED.
