Detailed Description

An interface for reading analog input, like for addressing a whole subdevice in comedi

Unit (MU) : Unit of what is actually read on the analog channel (e.g. Volt)

Definition at line 68 of file AnalogInInterface.hpp.

Member Enumeration Documentation

enum RTT::dev::AnalogInInterface::AnalogReference

Constructor & Destructor Documentation

RTT::dev::AnalogInInterface::AnalogInInterface ( ) [inline]

Create a not nameserved AnalogInInterface instance.

Definition at line 85 of file AnalogInInterface.hpp.

RTT::dev::AnalogInInterface::AnalogInInterface ( const std::string & name ) [inline]

Create a nameserved AnalogInInterface. When name is not "" and unique, it can be retrieved using the AnalogOutInterface::nameserver.

Definition at line 92 of file AnalogInInterface.hpp.

virtual RTT::dev::AnalogInInterface::~AnalogInInterface ( ) [inline, virtual]

Definition at line 96 of file AnalogInInterface.hpp.

Member Function Documentation

virtual void RTT::dev::AnalogInInterface::arefSet	(	unsigned int	chan,
		unsigned int	aref
	)		`[pure virtual]`

Set the analog reference of a particular channel. We took (for now) the comedi API for this, where every aref (eg. Analog reference set to ground (aka AREF_GROUND) corresponds to an unsigned int.

See also:: AnalogReference

Implemented in RTT::FakeAnalogDevice.

int RTT::dev::AnalogInInterface::binaryHighest ( ) const [inline]

Returns the binary highest value

Deprecated:: Do not use. Should return rawRange() in all implementations.

Definition at line 174 of file AnalogInInterface.hpp.

int RTT::dev::AnalogInInterface::binaryLowest ( ) const [inline]

Returns the binary lowest value.

Deprecated:: Do not use. Should return zero in all implementations.

Definition at line 168 of file AnalogInInterface.hpp.

unsigned int RTT::dev::AnalogInInterface::binaryRange ( ) const [inline]

Returns the binary range (e.g. 12bits AD -> 4096)

Deprecated:: by rawRange()

Definition at line 162 of file AnalogInInterface.hpp.

virtual double RTT::dev::AnalogInInterface::highest ( unsigned int chan ) const [pure virtual]

Returns the highest measurable input expressed in MU's for a given channel

Implemented in RTT::FakeAnalogDevice.

virtual double RTT::dev::AnalogInInterface::lowest ( unsigned int chan ) const [pure virtual]

Returns the current lowest measurable input expressed in MU's for a given channel

Implemented in RTT::FakeAnalogDevice.

virtual unsigned int RTT::dev::AnalogInInterface::nbOfChannels ( ) const [pure virtual]

Returns the total number of channels.

Implemented in RTT::FakeAnalogDevice.

virtual void RTT::dev::AnalogInInterface::rangeSet	(	unsigned int	chan,
		unsigned int	range
	)		`[pure virtual]`

Set the range of a particular channel. We took (for now) the comedi API for this, where every range (eg. -5/+5 V) corresponds to an unsigned int. You should provide a mapping from that int to a particular range in your driver documentation

Implemented in RTT::FakeAnalogDevice.

virtual unsigned int RTT::dev::AnalogInInterface::rawRange ( ) const [pure virtual]

Returns the absolute maximal range (e.g. 12bits AD -> 4096).

Implemented in RTT::FakeAnalogDevice.
