rkk 1:a1f3bd291a0c 20 * Library for Pressure Sensors of type MS5803-x of MEAS Switzerland (www.meas-spec.com).
rkk 1:a1f3bd291a0c 21 * The driver uses I2C mode (sensor's Protocol Select (PS) pin pulled to high).
rkk 1:a1f3bd291a0c 22 * MS5803-01BA (Barometer Sensor (Altimeter)) was successfully tested by Raig Kaufer.
rkk 1:a1f3bd291a0c 23 * MS5803-14BA (Underwater Pressure Sensor 14 bar) was successfully tested by Robert Katzschmann
rkk 1:a1f3bd291a0c 24 * Other types of MEAS are compatible but not tested
rkk 1:a1f3bd291a0c 25 * Written by Raig Kaufer, distribute freely!
rkk 1:a1f3bd291a0c 26 * Revised by Robert Katzschmann
