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> |

.. _max30101: MAX30101 Heart Rate Sensor ########################## Overview ******** A sensor application that demonstrates how to poll data from the max30101 heart rate sensor. Building and Running ******************** This project configures the max30101 sensor on the :ref:`hexiwear_k64` board to enable the green LED and measure the reflected light with a photodiode. The raw ADC data prints to the console. Further processing (not included in this sample) is required to extract a heart rate signal from the light measurement. .. zephyr-app-commands:: :zephyr-app: samples/sensors/max30101 :board: hexiwear_k64 :goals: build :compact: Sample Output ============= .. code-block:: console GREEN=5731 GREEN=5750 GREEN=5748 GREEN=5741 GREEN=5735 GREEN=5737 GREEN=5736 GREEN=5748 <repeats endlessly>
