Method Summary

IInputPin	bindInputPin(PinDescriptor pidx) register an input only pin and return the accessor object for it
IIOPin	bindIOPin(PinDescriptor pidx) register an input/output pin and return the accessor object for it
IOutputPin	bindOutputPin(PinDescriptor pidx) register an output only pin and return the accessor object for it
boolean	getPinValue(PinDescriptor pidx) get the current value of the pin, this can be called on both outputs and inputs, if the pin is not a scalar type the return value will by either 0 or 1
void	setPinDirection(PinDescriptor pidx, boolean output) set the pin direction, if output > 0 its set to an output if output == 0 its set to an input.
void	setPinValue(PinDescriptor pidx, boolean value) Ask the controller to set the pin value.

Method Detail

bindOutputPin

IOutputPin bindOutputPin(PinDescriptor pidx)

register an output only pin and return the accessor object for it

Parameters:

pidx - pin to access

Returns:

accessor object

bindInputPin

IInputPin bindInputPin(PinDescriptor pidx)

register an input only pin and return the accessor object for it

Parameters:

pidx - pin to access

Returns:

accessor object

bindIOPin

IIOPin bindIOPin(PinDescriptor pidx)

register an input/output pin and return the accessor object for it

Parameters:

pidx - pin to access

Returns:

accessor object

setPinValue

void setPinValue(PinDescriptor pidx,
                 boolean value)

Ask the controller to set the pin value.

Parameters:

pidx - pin to set value of

value - binary value

getPinValue

boolean getPinValue(PinDescriptor pidx)

get the current value of the pin, this can be called on both outputs and inputs, if the pin is not a scalar type the return value will by either 0 or 1

setPinDirection

void setPinDirection(PinDescriptor pidx,
                     boolean output)

set the pin direction, if output > 0 its set to an output if output == 0 its set to an input.
