Constructor Detail

IOPin

public IOPin(PinDescriptor idx,
             IGPIOController cntrl)

Method Detail

setHigh

public void setHigh()

Description copied from interface: IOutputPin

Sets pin output high

Specified by:

setHigh in interface IOutputPin

setLow

public void setLow()

Description copied from interface: IOutputPin

Sets pin output low

Specified by:

setLow in interface IOutputPin

setHigh

public void setHigh(boolean high)

Specified by:

setHigh in interface IOutputPin

Parameters:

high - boolean. If true, output is set high, otherwise output is set low.

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.

Specified by:

waitForChange in interface IInputPin

isOutput

public boolean isOutput()

Description copied from interface: IIOPin

Ask if this pin is an output. Pins are initially inputs. Note that it is possible to query the current pin setting of an output pin using isHigh() and isLow().

Specified by:

isOutput in interface IIOPin

Returns:

true if this pin is currently set to be an output

setAsOutput

public void setAsOutput(boolean b)

Specified by:

setAsOutput in interface IIOPin

Parameters:

b - if b is true the pin becomes an output, if false it becomes an input

getIndex

public PinDescriptor getIndex()
