Asynchronous MS5611 Barometric Pressure & Temperature Sensor Arduino Library
This library use I2C to communicate, so only 2 pins are required to interface with the sensor. Unlike most other MS5611 libraries, this library does not use delay() to wait until a measurement is received by the sensor. Rather, it initiates the measurement and lets the user check back at a later time to read it.
Based on the Arduino-MS5611 library by jarzebski.
MS5611_pressure.ino - gets the pressure in Pascals asynchronously
MS5611_adjusted_pressure.ino - gets the pressure in Pascals asynchronously, adjusted for temperature and using the factory calibration data
Use begin() to initialize the sensor. It will return false if no sensor is detected.
Use requestTemperature() or requestPressure() to request a temperature or pressure measurement, respectfully.
These functions will return false if a measurement is already in progress. Not more than one measurement may be in progress at a time, regardless of the type.
Use temperatureReady() or pressureReady() to check whether the temperature or pressure measurement is ready.
These functions return a true or false value.
Use readRawTemperature() or readRawPressure() to read the temperature, in Celsius, or pressure, in Pascals, after the measurement is ready.
These measurements aren't adjusted using calibration data from the factory, and the temperature is not compensated for in the pressure reading. This was done to make the library as preformant as possible for users who do not need this feature.
If you do want to adjust the temperature value using the calibration data, which is recommended, pass the output of readRawTemperature() to adjustTemperature().
If you want to adjust the pressure value using the calibration data and temperature, pass the output of readRawPressure() to adjustPressure(). YOU MUST also pass the output of readRawTemperature() as a second argument.
You can calculate the altitude from a given pressure by passing the pressure, in Pascals, to getAltitude(). You can optionally specify the sea level pressure as a second argument.
You can calculate the sea level pressure by passing a pressure, in Pascals and the corresponding altitude, in Meters, to getSeaLevel().
You can get and set the sensor's oversampling setting with getOversampling() and setOversampling(), respectfully.
