Sebastian Bøe 55ee53ce91 cmake: Prepend 'cmake_minimum_required()' into 'app' build scripts Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the application and test build scripts. Modern versions of CMake will spam users with a deprecation warning when the toplevel CMakeLists.txt does not specify a CMake version. This is documented in bug #8355. To resolve this we include a cmake_minimum_required() line into the toplevel build scripts. Additionally, cmake_minimum_required is invoked from within boilerplate.cmake. The highest version will be enforced. This patch allows us to afterwards change CMake policy CMP000 from OLD to NEW which in turn finally rids us of the verbose warning. The extra boilerplate is considered more acceptable than the verbosity of the CMP0000 policy. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>		2018-08-15 04:06:50 -07:00

AMG88XX Infrared Array Sensor
#############################

Overview
********

This sample application periodically reads the 8x8 temperature array from
the AMG88XX sensor and displays its values to the serial console.
The sample can also be configured to be triggered when the upper threshold
of 27 |deg| Celsius has been reached.

Requirements
************

The Panasonic AMG88XX is an 8x8 (64) pixel infrared array sensor available
only in a SMD design. Here are two sources for easily working with this sensor:

- `AMG88xx Evaluation Kit`_
- `Adafruit AMG8833 8x8 Thermal Camera Sensor`_

We used the Evaluation Kit mounted on FRDM-K64F board.
On the Evaluation Kit, all jumpers except the J11 must be removed.

This sample uses the sensor APIs and the provided driver for the AMG88xx sensor.

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

This sample reads from the sensor and outputs sensor data to the console every
second. If you want to test the sensor's trigger mode, specify the trigger
configuration in the prj.conf file and connect the interrupt output from the
sensor to your board. For the FRDM-K64F we tested, pin PTC2 must be muxed as
GPIO. You can change the upper threshold values by editing the sample.
The default upper threshold value is 27 |deg| Celsius (80.6 |deg| Fahrenheit).

The sensor array data is output every second.
