Доброго времени суток, Использую библиотеку для DS3231*/*DS3231.cpp - Arduino/chipKit library support for the DS3231 I2C Real-Time Clock Copyright (C)2015 Rinky-Dink Electronics, Henning Karlsen. All right reserved This library has been made to easily interface and use the DS3231 RTC with an Arduino or chipKit. You can find the latest version of the library at http://www.RinkyDinkElectronics.com/ This library is free software; you can redistribute it and/or modify it under the terms of the CC BY-NC-SA 3.0 license. Please see the included documents for further information.* пробую собрать на основе этого модуля и Нано недельный таймер, чтобы включать/выключать по времени и дню недели. Подскажите, как правильно вытаскивать конкретно часы, минуты, дни недели? Или как кто видит реализовать данную задачу? Заранее спасибо за конкретику.
Там же все в документации расписано и даже примеры есть. Что конкретно непонятно то? Код (C++): // DS3231_Serial_Hard // Copyright (C)2015 Rinky-Dink Electronics, Henning Karlsen.
