|
Analogue input for the Beaglebone Black. Reads an analogue pin when triggered
|
|
</p>
|
|
<p>The output message topic is the node topic: the output message value is the
|
|
scaled analogue input or NaN if a read error occurs.
|
|
</p>
|
|
<p>
|
|
Simple linear scaling is defined by setting the output values required for input
|
|
values of 0 and 1. You can apply more complicated scaling, e.g. for sensor linearisation,
|
|
by defining breakpoints at intermediate input values, with the desired output for
|
|
each. Values between breakpoints are linearly interpolated.
|
|
</p>
|
|
<p>
|
|
To reduce the effect of noise, enable averaging. This will read the input pin
|
|
voltage ten times in rapid succession for each input message and output the mean value.
