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> |

.. _96b_carbon_multi_thread_blinky: Basic Thread Example #################### Overview ******** This example demonstrates spawning of multiple threads using K_THREAD_DEFINE. The example works by spawning three threads. The first two threads control a separate LED. Both of these LEDs (USR1 and USR2) have their individual loop control and timing logic defined by separate functions. After either thread toggles its LED, it also pushes information into a FIFO identifying which thread toggled its LED and how many times it was done. The third thread, ``uart_out()``, uses printk (over the UART) to display the information that comes through the FIFO. - blink1() controls the USR1 LED that has a 100ms sleep cycle - blink2() controls the USR2 LED that has a 1000ms sleep cycle Each thread is then defined at compile time using K_THREAD_DEFINE.
