begin()

initialise bus i2c/spi. Initialise sensor with given parameters / settings. Checks chip id. Supported chip IDs:
  • 0x56 - BMP280
  • 0x57 - BMP280
  • 0x58 - BMP280
  • 0x60 - BME280
 default exposed parameters setSampling. bpm.begin(addr, theWire, scl, sda)
 bpm: a variable of type BMP280.
 addr: bus sensor address i2c BME280_ADDRESS(0x77) and BME280_ADDRESS_ALTERNATE(0x76) - default BME280_ADDRESS.
 theWire: object pointer Wire - default Wire.
 scl: pin SCL - default SCL(9).
 sda: pin SDA - default SDA(10).
 bool - true on success, false otherwise bpm.begin(spi, sck, miso, mosi, ss)
 bpm: a variable of type BMP280.
 theWire: object pointer SPI .
 sck: custom SCK pin
 miso: custom MISO pin
 mosi: custom MOSI pin ss: custom SS pin bool - true on success, false otherwise
