Detailed Description

A test class which replaces a real device driver. It reproduces on the output what it gets on the input.

Member Function Documentation

virtual void RTT::FakeAnalogDevice::arefSet	(	unsigned	chan,
		unsigned	aref
	)			`[inline, 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

Implements RTT::dev::AnalogInInterface.

virtual double RTT::FakeAnalogDevice::highest ( unsigned chan ) const [inline, virtual]

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

Implements RTT::dev::AnalogInInterface.

Definition at line 117 of file FakeAnalogDevice.hpp.

virtual double RTT::FakeAnalogDevice::lowest ( unsigned chan ) const [inline, virtual]

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

Implements RTT::dev::AnalogInInterface.

Definition at line 112 of file FakeAnalogDevice.hpp.

virtual unsigned int RTT::FakeAnalogDevice::nbOfChannels ( ) const [inline, virtual]

Returns the total number of channels.

Implements RTT::dev::AnalogInInterface.

Definition at line 70 of file FakeAnalogDevice.hpp.

virtual void RTT::FakeAnalogDevice::rangeSet	(	unsigned	chan,
		unsigned	range
	)			`[inline, 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

Implements RTT::dev::AnalogInInterface.

Definition at line 64 of file FakeAnalogDevice.hpp.

virtual unsigned int RTT::FakeAnalogDevice::rawRange ( ) const [inline, virtual]

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

Implements RTT::dev::AnalogInInterface.
