getVoltageUnfiltered

public double getVoltageUnfiltered()

setLPF

public void setLPF(double alpha)

Set the alpha coefficient for the low-pass filter. y[n] = alpha*y[n-1] + (1-alpha)*x[n]. I.e., values near one represent low-pass filters with greater effect. The nominal sample rate is 500Hz.

Parameters:

alpha - [0,1].
