Detailed Description

The Register contains parameters for the statistic functions available on the FLT board.

(Implemented in Flt Version 2.00)

The mean value and the variance of the ADC input signal are calculated. This does NOT necessarily correspond with the content of ADC Memory of the FLT boards.

Changes:

29.8.01 ak: Bug in loop for broadcast replacement fixed (started with 1 instead of 0!).
10.7.01 ak: Calculate of the statistics over now 2^16 samples (elongation by 6bit)

Member Function Documentation

void FltStatistic::disable ( int ch )

Disable the statisic functions.

void FltStatistic::disable ( )

Disable the statisic functions for all channels.

void FltStatistic::enable ( int ch )

Enable the statisic functions.

void FltStatistic::enable ( )

Enable the statisic functions for all channels.

bool FltStatistic::get	(	int	ch,
		int *	offset,
		unsigned long *	n
	)

Get the parameters for the statistical functions.

int FltStatistic::getOffset ( int ch )

Returns:: The offset for the ADC values.

int FltStatistic::getSamples ( int ch )

Returns:: The number of samples used in the statistic functions.

bool FltStatistic::isEnabled ( int ch )

Enable the statisic functions.

Returns true if the evaluation of the statistic functions is turned on.

void FltStatistic::set	(	bool	enabled,
		int	offset,
		unsigned long	n
	)

Broadcast the same parameters to all channels.

void FltStatistic::setOffset	(	int	ch,
		int	offset
	)

Defines a offset for the ADC values.

The statistics use the variable x, where x is calulated from the ADC values by the formular

x = ADC_i - offset.

The offset can take values from 0..1023.

void FltStatistic::setOffset ( int offset )

Defines the offset for all channels.

void FltStatistic::setSamples	(	int	ch,
		int	n
	)

Defines the number of samples used in the statistic functions.

Valid values for the number of samples are from 0..2^16-1.

void FltStatistic::setSamples ( int n )

Defines the number of samples for all channels.

int FltStatistic::writeBitsByName	(	int	ch,
		char *	name,
		unsigned long	data
	)		`[virtual]`

Write bit fields by name.

Know fields are

offset
samples
off
