Constructor Detail

BinaryScalar

public BinaryScalar(PinDescriptor idx,
                    int r,
                    IADCController cntrl)

Constructor

Parameters:

idx - Pin that

Method Detail

getValue

public int getValue()

Specified by:

getValue in interface IScalarInput

Returns:

current value of the input

getRange

public int getRange()
             throws IOException

Specified by:

getRange in interface IScalarInput

Returns:

maximum possible value that could be returned from the input device

Throws:

IOException

isLow

public boolean isLow()

Specified by:

isLow in interface IInputPin

Returns:

true if the input bit is low.

isHigh

public boolean isHigh()

Specified by:

isHigh in interface IInputPin

Returns:

true if the input bit is high.

waitForChange

public void waitForChange()

Description copied from interface: IInputPin

Blocks the caller waiting for a change. Note that this function may use a polling implementation that prevents deep sleep. To avoid this, use EDemoBoard.waitForPinChange().

Specified by:

waitForChange in interface IInputPin

getIndex

public PinDescriptor getIndex()
