Parameter
These interpolation functions are useful for converting
between engineering units and raw analog counts.
Pamux analog input and output values range between 0
and FFF hex (4,095 decimal). These values typically
correspond to engineering units, such as pH and psi.
For example, to convert raw counts (from 0 to FFF hex)
to a percentage, use:
float fPercent=PamuxUtilScaleI2F
(0,0xFFF,0.0,100.0,RawCount);
Converts an array of boolean (0 or not
0) values to a bit packed integer.
Converts a bit packed integer to an
array of boolean (1 or 0) values.
Qty indicates the number of bits to be
packed or unpacked.
