Тема: Часы на ИВЛ1-7/5 на Atmega8

Собрал часы на атмега8. При прошивке столкнулся с проблемой, скетч не компилировался выдавало ошибку. После замены переменной min на minute скетч компилируется часы идут. Хотелось бы расширить функционал часов и добавить в эти часы датчик температуры на ds18b20 с отображением градусов, будильник с зажиганием одного сегмента на индикаторе будильник. Часы запустил на индикаторе ИЛЦ7-4/7Л.

вот так они пока что без корпуса выглядят.

Опубликуйте скетч который используете.

Re: Часы на ИВЛ1-7/5 на Atmega8

Тестирование датчика температуры

к PC0 подключите DS18B20

Мне надо посмотреть что померил датчик

Измерение температуры производится 1 раз в минуту в 0 секунд

Посмотрите что покажет индикатор

Должно быть типа 275 (27,5 гр)

Если все работает, как выводить температуру, сколько раз в минуту, в какое время минуты, как отображать

Варианты

27.5_С
27.5С_
_27.5С
27.5*C

В индикаторе есть точка и колокольчик, у Вас под каждый анод колокольчика и точки отдельный транзисторный ключ? По скетчу видно что колокольчик не должен работать, он в скетче не прописан, но должна работать точка, мигать в такт секунд.

По скетчу видно, что на точке нет транзисторного ключа, на точку просто подано напряжение через резистор, на анод точки постоянно подается напряжение, управление точкой осуществляется через сетку. Этот вопрос надо решать.

У Вас сейчас свободны пины PD3 PD4 , все остальное занято.

Анод точки надо пустить через транзисторный ключ, а сетку запитать на постоянку, и еще добавить ключ для колокольчика, остается всего один свободный пин. Его можно использовать для пищалки будильника.

Но это все позже, надо сначала с датчиком температуры разобраться.

Re: Часы на ИВЛ1-7/5 на Atmega8

27.5С такой бы формат температуры устроил. можно было бы без десятых пол шкалы где часы градусы в цифрах а пол школы верхний нолик и С большое.

почему то время показывает и все. при прошивке засвет восьмерок подмаргивание. после пршивки только время идет и все.
