Emery Premeaux / Mbed 2 deprecated MS4525_pitot_tube

Library and demo program for MS4525DO differential pressure sensor based pitot tube, using I2C interface

Dependencies:   mbed

Temperature values are correct. But I dont trust the PSI and airspeed (especially airspeed).

Code blended and ported from a combination of the following sources:
