See DS3231_HAL.hfor the description of parameters and use.
To use this in your pico project:
- copy this directory (DS3231_HAL) as a subdirectory of the base project directory or add it as a git submodule
- add the following line to the main CMakeLists.txt, after the
add_executable(...)statement:
add_subdirectory( DS3231_HAL ) - MemI2C also needs to be added your project.
- At least version 3.13 of CMake is needed, make sure the main CMakeLists.txt begins with a
cmake_minimum_required(VERSION 3.13)(or later) line to correctly set policies. - use
#include "DS3231_HAL.h"as needed.
