Digital I/O operations on a Device.

Member Function Documentation

ReadInputBit()

bool ReadInputBit

(

int

port

)

Reads a single input port from the device.

Parameters

port	Port index to read.

Returns

true for input high state; false for low.

ReadInputGroup()

BitVector32 ReadInputGroup

(

int

group

)

Reads the input group from the device.

An input group consists of 32 single ports. Non existent ports are always 0. Thus there are only more than one input group if InputCount is larger than 32.

Parameters

group

Group index to read.

Returns

A BitVector32 representing the 32 bits of the input group selected by group .

ReadOutputBit()

bool ReadOutputBit

(

int

port

)

Reads a single output port from the device.

Parameters

port	Port index to read.

Returns

true for output high state; false for low.

ReadOutputGroup()

BitVector32 ReadOutputGroup

(

int

group

)

Reads the output group from the device.

An output group consists of 32 single ports. Non existent ports are always 0. Thus there are only more than one output group if OutputCount is larger than 32.

Parameters

group

Group index to read.

Returns

A BitVector32 representing the 32 bits of the output group selected by group .

WriteOutputBit()

void WriteOutputBit	(	int	port,
		bool	value
	)

Write a single output port to the device.

Parameters

port	Port index to write.
value	true for hight state; false for low.

WriteOutputGroup() [1/2]

void WriteOutputGroup	(	int	group,
		BitVector32	value
	)

Writes the output group to the device.

An output group consists of 32 single ports. Non existent ports are ignored. Thus there are only more than one output group if OutputCount is larger than 32.

Parameters

group	Group index to write.
value	Vector of port states.

WriteOutputGroup() [2/2]

void WriteOutputGroup	(	int	group,
		BitVector32	value,
		BitVector32	mask
	)

Writes the mask ed output group to the device.

An output group consists of 32 single ports. Non existent ports are ignored. Thus there are only more than one output group if OutputCount is larger than 32.

Parameters

group	Group index to write.
value	Vector of port states.
mask	Bit mask for the bits being actually set to the ports.
