Ulf Magnusson a84ded74ea dts: Replace status = "ok" with status = "okay" The DT spec. only has "okay" and not "ok". The Linux kernel has around 12k "okay"s and 300 "ok"s. The scripts/dts scripts only check for "disabled", so should be safe re. those at least. The replacement was done with git ls-files \| xargs sed -i 's/status\s=\s"ok"/status = "okay"/' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>		2019-06-14 19:51:13 -05:00

ams iAQcore Indoor air quality sensor
#####################################

Overview
********

This sample application demonstrates how to use the ams iAQcore sensor to
measure CO2 equivalent and VOC. The CO2 value is a predicted value derived from
VOC. The values are fetched and printed every second.

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

This sample application uses the sensor connected to the i2c stated in the
iaq_core.overlay file.
Flash the binary to a board of choice with a sensor connected.
This sample can run on every board with i2c.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensors/ams_iAQcore
   :board: nucleo_f446re
   :goals: build flash
   :compact:
