Detailed Description

template<class T, class R = int>
class InputCalibrator< T, R >

Class that performs calibration and scaling of an incoming integer value from an A/D converter or other input device.

It is a templated class, and the template parameter must be a class capable of scaling the incoming values.

Constructor & Destructor Documentation

InputCalibrator()

template<class T, class R = int>

InputCalibrator< T, R >::InputCalibrator	(	const R	in_min,
		const R	in_max,
		const T &	c,
		unsigned int	idx = 0 )

Constructor.

Takes a converter as argument.

Parameters

in_min	Minimum integer value
in_max	Maximum integer value
c	Converter of (template) type T, the operation operator() (const double x) should exist for values between in_min and in_max, and should produce the required converted/scaled value.
idx	Optional index to be stored with the calibrator.

bitDifference()

template<class T, class R = int>

R InputCalibrator< T, R >::bitDifference

(

const double

r

)

const

Return the difference between the given value and the measured value in bit domain.

Parameters

r	Value for comparison

Returns

• 0 if the difference is 1 bit or less
• 1 if the value is two bits larger
• -1 if the value is two bits smaller
• 2 respectively -2 if the value is three bits or more larger or smaller.

index()

template<class T, class R = int>

unsigned int InputCalibrator< T, R >::index ( ) const

inline

The index is a variable for user convenience, e.g.

to remember where in an array of raw data the input value is stored.
