Library and demo program for MS4525DO differential pressure sensor based pitot tube, using I2C interface
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:
- https://forum.arduino.cc/index.php?topic=309653.0
- https://github.com/PX4/Firmware/blob/master/src/modules/commander/airspeed_calibration.cpp
- https://github.com/PX4/Firmware/tree/master/src/drivers/differential_pressure/ms4525
