flexAnaInAverageSetting

int flexAnaInAverageSetting(Flex_IOPin *pin, float alpha);

DESCRIPTION

Sets the averaging alpha value (weight value) for a given ADC channel to read averaged ADC

data. To read the average ADC data use the following functions:

• flexAnaInAverage() - read averaged raw data

• flexAnaInVoltsAverage() - read averaged voltage

• flexAnaInmAmpsAverage() - read averaged current

If you set the alpha value to 1 for a given A/D channel, then you will get the actual unaltered

raw data value.

This function is non-reentrant.

PARAMETERS

pin Pointer to the information structure for the selected pin.

alpha Value for averaging the given analog input channel; the recommended range

is 0.001–1.0.

RETURN VALUE

0: success

-1: invalid alpha value

-2: error (not an analog input?)
