Detailed Description

Digital I/O operations on a Device.

Constructor & Destructor Documentation

DigitalIO()

DigitalIO ( Device  device )

package

Creates a DigitalIO object from the given device .

Parameters

device

Parent 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.

Implements IDigitalIO.

ReadInputGroup()

BitVector32 ReadInputGroup

(

int

group

)

Reads a single output group from the device.

Parameters

group

Port index to read.

Returns

true for output high state; false for low.

Implements IDigitalIO.

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.

Implements IDigitalIO.

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

Implements IDigitalIO.

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.

Implements IDigitalIO.

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.

Implements IDigitalIO.

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.

Implements IDigitalIO.
