Abstract

This function provides smoothing of an analog input. The function calculates the smoothing value by adding S/16 of previous value with (16-S)/16 of actual value. The formula used is:
Out = ([Smooth_factor]/16)[Prev_value]+((16-[Smooth_factor])/16)[Input_value]
S = smoothing factor X1 = initial value/previous output X2 = new input from I/O table

Valid entries for S smooth factor

Provide minimal smoothing 1
Provide maximum smoothing 15
