С лживым С++ в килобайте много не надрыгаешь, а в ассемблер она играть не умеет.
Дык, уже давно известно что С++ здесь не при чём. Только прямые руки.
Что значит?
А… понЕл).
Это и называется “хобби”. Можно подумать, что коллекции 90% филателистов-любителей имеют хоть какую-то ценность ))

Поэтому нужно собирать прон. И для здоровья и мускулатуру развивает… специфическую. 
а сколько реально кнопок нужно? 3? 4? 5? 6? Не в теории, типа “хачу, чтобы и 10055 можно было”, а реально сколько надо?
А то, может рано мы списали обычный параллельным массив? Давайте, колитесь!
8 кнопок, 2 выхода.
Т.е. на 1 выход нужно посадить 4 кнопки?
Правильно?
pb0 и pb1 используются для управления реле
pb2 читает показания с ACS712
pb3 - чтение кнопок, через 10к подтянут к питанию, кнопки через резисторы на землю.
pb4 - чтение кнопок, через 10к стянут на землю, кнопки через резисторы на питание.
Меня всё устраивает в Вашем скетче. Но если есть возможность отследить нажатие нескольких кнопок одновременно, было бы интересно.
Но, как уже сказали выше, проще купить что-то иное, а это для повышения образованности)
Вот, я об этом и спрашиваю. Ответьте мне, Вам достаточно иметь 4 кнопки на одном аналоговом входе? Чётко ответьте. Если достаточно, то не вопрос, щас сделаем. Вот, если больше, там посложнее.
4 кнопки достаточно.
А на три не сговоримся?
Тогда вообще нет проблем. Сейчас дооптимизирую номиналы чуток и выложу решение
Да там и на 5-6 проблем нет.
У кого как. У Вас, может и нет.
Правила Кирхгофа никто, по-моему, не отменял, имея схему леггко можно расччитать напряжение на входе при различных совместных нажатиях кнопок
Да, только затрахаешься подбирать резисторы, чтобы все комбинации нажатий оставались “различимыми”. Я сделал это “методом Британского музея”, сейчас оформляю пост с лучшими решениями.
Просто сам метод аналоговых кнопок, именно кнопок, кажется мне очень сомнительным, вот я и иронизрую, хотя аналоговый переключатель режиммоа очеень даже может быть
Ниже лежат готовые решения для 2-х, 3-х, 4-х, 5-ти и 6-ти кнопок. Но последние я бы не рекомендовал, ниже будет понятно почему. А для 2-4 кнопок можно просто брать указанные номиналы и настраиваться на рассчитанные ожидаемые значение - никаких проблем.
Речь идёт о вот такой простейшей схеме (по сути такой же, как была у Вас, но перевёрнутой)
Как пользоваться решениями и что они означают.
Решение выглядит вот так:
Цифрами обозначены:
- Сопротивления резисторов R1-R4 (здесь и везде все сопротивления в килоомах);
- Сопротивление Pull-down резистора
- Комбинации кнопок. Единица - нажата, ноль – отпущена. Слева направо: S1, S2, S3 и S4;
- Значение на пине (уже готовое в “попугаях”), которого следует ожидать, если нажата соответствующая комбинация кнопок;
- Сопротивление всех резисторов делителя, если нажата соответствующая комбинация кнопок (это для оценки какой ток будет течь через делитель от питания к земле при нажатии этой комбинации кнопок).
- Минимальный зазор между значениями напряжений (№4). Собственно, это та величина, которая даёт Вам возможность отличать одну кнопку от другой.
Последний параметр очень важен, поясню. Если взять все значения на пине для различных комбинаций нажатия кнопок и найти два самых близкие из них, то это и будет зазор. В данном случае зазор 19, значит никакие две комбинации кнопок не дадут на пин значений более близких, чем 19. Это вполне позволит отличать комбинации друг от друга. Вот если бы зазор был 1, а то и 0, комбинации стали бы неотличимы.
19 – это самый лучший зазор, который удаётся получить для данной схемы для 4-х кнопок. Лучше на этой схеме получить невозможно. Я выбрал все варианты с зазором 19 и привёл под спойлером ниже. Вы можете брать любой, просто используйте указанные номиналы резисторов и pull-down резистора. Выбор между решениями тут по другим (не связанным с этой схемой) соображениям (например, по наличию резисторов). Я бы выбрал разумный pull-down (типа 10 кОм) – это то решение, что мы на примере смотрели, в общем списке оно тоже есть.
Также я просчитал для трёх кнопок (там наилучший зазор получается 47) и выбрал опять же все возможные комбинации с наилучшим зазором. Для двух кнопок наилучший зазор уже 121, комбинации я тоже привёл.

А вот для большего количества кнопок всё печальнее. Для 5-ти кнопок наилучший зазор – всего 9, а для 6-ти – всего 4. Это на пределе паспортной погрешности АЦП – я бы не стал рисковать. Но, приведу всё-таки несколько решений с лучшими зазорами (не все) для полноты изложения.
