https://github.com/sparkfun/SparkFun_BME280_Arduino_Library

This sketch configures two BME280 to produce comma separated values for use
in generating spreadsheet graphs.
in 10 being used for chip select.

Resources:
Uses Wire.h for I2C operation
Uses SPI.h for SPI operation

Development environment specifics:
Arduino IDE 1.6.4
Teensy loader 1.23
