Re: LED матрица max7219

Они есть, просто на фото не попало.

Re: LED матрица max7219

Здравствуйте!Подскажите,можно ли установить фоторезистор с другими характеристиками? У меня сопротивление освещённости 100-200кОм,сопротивление темноты 10-20мОм..

Re: LED матрица max7219

Можно использовать.

Если не хватить напряжения для нормального регулирования то используйте множитель:

int u = (ADCL|ADCH << 8);

заменить на

int u = (ADCL|ADCH << 8)*2;

Re: LED матрица max7219

Здравствуйте,воспроизвёл ваш проект,всё работает,но почему-то нет разделительных мигающих точек, когда показывает время.Я установил прошивку помеченную как "Аппаратный I2C...Что может быть не так?

Re: LED матрица max7219

Проверьте наличие импульсов с частотой 1 сек на выводе sqw модуля часов реального времени

Подскажите, пожалуйста, как проверить наличие импульсов.

Re: LED матрица max7219

Мультиметром померьте напряжение или подключите светодиод через 300 Ом.

Re: LED матрица max7219

Проверял, нет импульсов, на sqw-5вольт,устанавливал ещё 3 модуля rtc, такая же картина, RTC-DS3231...

Re: LED матрица max7219

Какой используете модуль часов реального времени?

Re: LED матрица max7219

Для Ds3231

ds_write(0x07, 0b00010000); // выход SQW, частота 1 Гц

замените на

ds_write(0x0E, 0b00010000); // выход SQW, частота 1 Гц

Re: LED матрица max7219

Возможно ли сделать такую настройку времени кнопками , что бы, например, при настройке минут ход секунд обнулялся (для более точной настройки времени)? Сейчас часы и минуты настраиваются, а ход секунд никак не корректируется (секунды идут, как начали идти при первом включении..)

В момент выхода из меню корректировки времени, секунды обнуляются.

Re: LED матрица max7219

Класс! Понравился проект, всё работает. Можно отключить показ календаря и влажность. То есть оставить температуру и время?

Re: LED матрица max7219

Как можно проверить модуль MAX7219. При заливке разных скетчей, в том числе и скетча с часами матрица не отображает время так, как на картинке. цифры сдвинуты и налезают одна на другую. Точки секунд смещены вниз. Есть ли какой-то скетч, чтобы можно было проверить правильность работы матрицы и контроллера в целом?
