This example shows how to connect to different I2C address and push to different Wire ports.
12+
13+
The BME280 has two I2C addresses: 0x77 (jumper open) or 0x76 (jumper closed)
14+
15+
This sketch configures the BME280 to read all measurements. The sketch also
16+
displays the BME280's physical memory and what the driver perceives the
17+
calibration words to be.
