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

This enum can be used to configure the arefSet() function.

Constructor & Destructor Documentation

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.

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.

Returns the binary highest value

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

Definition at line 174 of file AnalogInInterface.hpp.

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.

virtual int RTT::dev::AnalogInInterface::rawRead ( unsigned int  chan,
int &  value 
) [pure virtual]

Read a raw value from channel chan

Returns:
0 on sucess.

Implemented in RTT::FakeAnalogDevice.

virtual int RTT::dev::AnalogInInterface::read ( unsigned int  chan,
double &  value 
) [pure virtual]

Read the real value from channel chan

Returns:
0 on sucess.

Implemented in RTT::FakeAnalogDevice.

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

Resolution is expressed in bits / MU

Implemented in RTT::FakeAnalogDevice.
