Member Function Documentation

virtual bool isOn

(

unsigned int

bit = 0

)

const [pure virtual]

Inspect if a certain bit is on.

Parameters:

bit

The bit to check, starting from zero.

Returns:

true if the bit is high (1), false otherwise.

Referenced by DigitalInput::isOn().

virtual bool isOff

(

unsigned int

bit = 0

)

const [pure virtual]

Inspect if a certain bit is on.

Parameters:

bit

The bit to check, starting from zero.

Returns:

true if the bit is low (0), false otherwise.

virtual bool readBit

(

unsigned int

bit = 0

)

const [pure virtual]

Inspect a bit.

Parameters:

bit

The bit to check, starting from zero.

Returns:

true if the bit is high (1), false otherwise.

virtual unsigned int readSequence	(	unsigned int	start_bit,
		unsigned int	stop_bit
	)			const [pure virtual]

Inspect a sequence of bits.

Parameters:

	start_bit	The first bit to check.
	stop_bit	The last bit (inclusive) to check.

Returns:

a bit pattern denoting the bit status from start_bit to stop_bit where bit zero equals the value of start_bit.
