Macro reference

AddSample

	AddSample
Adds a sample to the first in first out sample buffer.
- FLOAT	Sample
Value to add into the FIFO buffer
- VOID	Return

GetDeviation

	GetDeviation
Gets the standard deviation of the values in the first in first out buffer
- FLOAT	Return

GetMean

	GetMean
Gets the mean of the values in the first in first out buffer
- FLOAT	Return

InitialiseFIFO

	InitialiseFIFO
initialises the first in first out buffer values to 0
- VOID	Return

SetSampleCount

	SetSampleCount
Sets the number of samples when using the variable sample count type.
- UINT	SampleCount

- VOID	Return

Property reference

	Properties
	Sample Count Type
Controls if the number of samples to determine the mean and deviation are fixed or variable, Fixed has some additional optimisations when adding samples but variable allows flexibility. The sample count for variable samples defaults to the max count and can be set using the SetSampleCount macro.
	Number of Samples
Fixed number of samples used to calculate the mean and deviation. Samples are first in first out so the newest sample will replace the oldest.
	Initial Sample Value
Sets the initial value of each sample when initialising the FIFO.
