Constructor & Destructor Documentation

RTT::dev::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_inThe digital input device to use to read the status.
bit_nrThe bit number to use on the device.
invertSet to true to return the inverted bit in isOn().

RTT::dev::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:
valueA reference to a boolean representing a digital input and which is used to read the status.
invertSet to true to return the inverted value in isOn().
