Peter Bigot 6e5db350b2 coccinelle: standardize k_sleep calls with integer timeouts 
Re-run with updated script to convert integer literal delay arguments to
k_sleep to use the standard timeout macros.

BME680: Integrated environmental sensor
#####################################################

Description
***********

This sample application periodically (every 3s) measures the ambient temperature
in degrees Celsius, atmospheric pressure in kilopascal, relative humidity in percentage,
and gas sensor resistance in ohms. The result is written to the console.

Wiring
*******

This sample uses the BME680 sensor controlled using the I2C interface.
Connect Supply: **VDD**, **VDDIO**, **GND** and Interface: **SDA**, **SCL**.
The supply voltage can be in the 1.8V to 3.6V range.
Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up
resistors.

Building and Running
********************

This project outputs sensor data to the console. It requires a BME680
sensor. It should work with any platform featuring a I2C peripheral interface.
It does not work on QEMU.
In this example below the :ref:`nrf52_pca10040` board is used.
