Constructor & Destructor Documentation

RTT::DigitalInput::DigitalInput	(	DigitalInInterface *	dig_in,
		unsigned int	bit_nr,
		bool	invert = false
	)			[inline]

Create an object to read the state of a switch which can be on or off.

Parameters:

	dig_in	The digital input device to use to read the status.
	bit_nr	The bit number to use on the device.
	invert	Set to true to return the inverted bit in isOn().

Definition at line 64 of file DigitalInput.hpp.

RTT::DigitalInput::DigitalInput	(	const bool &	value,
		bool	invert = false
	)			[inline]

Create an object to read the state of a boolean value which can be on or off.

Parameters:

	value	A reference to a boolean representing a digital input and which is used to read the status.
	invert	Set to true to return the inverted value in isOn().
