Yet Another Arduino BME280 and BMP280 Digital Pressure Sensor Library

home: https://bitbucket.org/christandlg/bmx280mi

sensors: https://www.bosch-sensortec.com/bst/products/all_products/bmp280 / https://www.bosch-sensortec.com/bst/products/all_products/bme280

Features:

• Supports I2C (via the Wire library) and SPI (via the SPI library) interfaces
• Supports other I2C and SPI libraries via inheritance
• Supports 64 bit pressure calculation
• Never blocks or delays (except for convenience functions)

Changelog:

• 1.2.3

  • added examples for ESP8266 and Normal Mode.

• 1.2.2

  • added function getPressureI64() that returns the pressure as in Pa a <64,8> fixed point number.

• 1.2.1

  • added SoftWire Example.

• 1.2.0

  • fixed a bug #3 where getPressure(), getPressure64() and getHumitiy would depend on getTemperature() to be called immediately before (since last time hasValue() returned true) in order to return correct values.

• 1.1.2

  • updated documentation on function hasValue()
  • updated examples

• 1.1.1

  • fixed an error in 64 bit pressure calculation

• 1.1.0

  • added 64 bit pressure calculation

• 1.0.0

  • added new classes BMx280TwoWire and BMx280SPIClass for TwoWire and SPIClass interfaces -moved BMx280I2C and BMx280SPI classes into their own respecitve source files, further separating data processing from communications
  • when updating from an earlier version and using the BMx280I2C or BMx280SPI classes, change #include <BMx280MI.h> to #include <BMx280I2C.h> or #include <BMx280SPI.h>, respectively
  • simplified function BMx280MI::measure()

• 0.0.2

  • humidity measurement implemented

• 0.0.1

  • initial release
