      avrora.sim.platform.LED

All Implemented Interfaces:

Microcontroller.Pin.Output

public class LED

extends Microcontroller.OutputPin

The LED class implements an LED (light emitting diode) that can be hooked up to a pin on the microcontroller. The LED prints its state when it is initialized and each time it is turned on or off.

Method Detail

write

public void write(boolean level)

Description copied from interface: Microcontroller.Pin.Output

The write() method is called by the simulator when the program writes a logical level to the pin. The device can then take the appropriate action.

Parameters:

level - a boolean representing the logical level of the write

enablePrinting

public void enablePrinting()

disablePrinting

public void disablePrinting()

getFSM

public FiniteStateMachine getFSM()

The getFSM() method returns the FiniteStateMachine instance corresponding to this LED. This finite state machine representation allows probes to be inserted that are notified when the state of the LED is changed.

Returns:

an instance of the FiniteStateMachine class for this LED instance
