Простые часы Pic12f629 & tm1637
Прошивка и файл проекта
clock12f629tm1637.rar
Часы первичные для механических часов "Стрела". Pic12f675(629)
Прошивка и файл проекта
master_clock2pic12f.rar
Простые часы в другой программе MPLAB IDE. Схема такая же.
pic12f675tm163732867hz.rar
Второй вариант с DS3231.
pic12f675tm1637ds3231.rar
Третий вариант с DS1307.
pic12f675tm1637ds1307.rar
Интересно, что в DS1307 7бит в регистре секунд установить в ноль надо.
Термометр DS18b20.

}Индикатор литиевого аккумулятора. Размышления в теории. > 4.2в мигает зеленый светодиод. 4,2 - 3,8в горит зеленый светодиод.3,8-3,4в горит желтый светодиод.3,4-3в горит красный светодиод.<3в мигает красный светодиод. Обычно измеряют напряжение с помощью опорного напряжения. АЦП результат = Uвх*1024/Uref. Думаю, если сделать так, чтобы не делать делитель напряжения. Uвх будет опорным напряжением, например 2.5(1.5)в через TL431(432). А Uref будет настроен на U питания. Главное, чтобы U питания был не меньше 2.5в. Хотя защита литиевого аккумулятора сработает при напряжении 2.5в.

А вы можете предоставить виде графического изображения во Flowcode или сам проект во Flowcode? А то скачал архив а там нет файла проекта во Flowcode. И какая у вас версия программы Flowcode?
