Calculating corrected Altitude from Pressure & Temperature using Teensy 3.2, BME280, and library from farmerkeith

[samarjay]

@samarjay

This library provides two functions for this relationship, as follows:

calcAltitude (pressure, seaLevelhPa);
calcNormalisedPressure (pressure, altitude);

There is also a simpllified version, which assumes the standard sea level pressure of 1013.15 hPa.

calcAltitude (pressure); // standard seaLevelPressure assumed

as described here...
