Здравствуйте, хочу повторить схему металлоискателя на ардуино, есть такой код, в коде есть дисплей 1602 без адаптера I2C у меня адаптер запаян и не хочется отпаивать. Прошу помощи в прописке данного адаптера в этот код. Сам пробовал вставлять адаптер с адресом закоментировав при этом выводы на дисплей но вылазит ошибка.
// Induction balance metal detector
// We run the CPU at 16MHz and the ADC clock at 1MHz. ADC resolution is reduced to 8 bits at this speed.
// Timer 1 is used to divide the system clock by about 256 to produce a 62.5kHz square wave.
// This is used to drive timer 0 and also to trigger ADC conversions.
// Timer 0 is used to divide the output of timer 1 by 8, giving a 7.8125kHz signal for driving the transmit coil.
// This gives us 16 ADC clock cycles for each ADC conversion (it actually takes 13.5 cycles), and we take 8 samples per cycle of the coil drive voltage.
// The ADC implements four phase-sensitive detectors at 45 degree intervals. Using 4 instead of just 2 allows us to cancel the third harmonic of the
// coil frequency.
// Timer 2 will be used to generate a tone for the earpiece or headset.
// Other division ratios for timer 1 are possible, from about 235 upwards.
// Wiring:
// Connect digital pin 4 (alias T0) to digital pin 9
// Connect digital pin 5 through resistor to primary coil and tuning capacitor
// Connect output from receive amplifier to analog pin 0. Output of receive amplifier should be biased to about half of the analog reference.
// When using USB power, change analog reference to the 3.3V pin, because there is too much noise on the +5V rail to get good sensitivity.

Вместо библиотеки LiquidCrystal используйте библиотеку LiquidCrystal_I2C
Все библиотеки на месте и работаю проверено на хало ворлд. Я может чуть знаю что такое ардуино верхушек нахватался но осоцилограф на ардуино спаял.

если "все библиотеки на месте и работают" - в чем тогда вопрос?
Еще раз - Вместо библиотеки LiquidCrystal используйте библиотеку LiquidCrystal_I2C
Или буковки I2C в конце названия ни о чем не говорят?

Согласен, я готовлю:) но не в ардуино, яж говорю только верхушек нахватался.
Согласен долго я искал библиотеку что бы хоть холо ворл заработал.
Вод подробная ошибка.

Как? наверное потому я и здесь со своей просьбой.

обычно если сам не можешь заказываешь компетентный сервис )))
Так научите это ... как сложно. Да и зачем нужна lcdbargraph.h если я собираюсь под i2c переписать код. С меня в контакте ардуинщик-бизнесмен запросил 1000 рублей это не вы случайно?
это не я и, ...так как ты просишь чтобы один неуч учил второго неуча в этом случае ставка будет сильно выше, 4 часа 7 тыр )))
PS это не договор оферты...размышления вслух...
Ясно зря зашёл, ну всё равно спасибо, здоровья вам и удачи.
Ты богатый и очереди у тебя? Удачи в бизнесе.
Ты богатый и очереди у тебя? Удачи в бизнесе.
А ты бедный и безмозглый.
Готовое купи, это дешевле.
Ясно зря зашёл, ну всё равно спасибо, здоровья вам и удачи.
почему же зря, скетч тебе дали поправленный (заметь - безвозмездно), осталось решить или новый дисплей купить, или у этого выпаять контроллер или штуку заплатить тому, кто тебе предлагал ...это если по быстрому...
PS обычно хорошим тоном считается приводить ссылку на автора проекта
Не забываем, что не все библиотеки LCD_I2C поддерживают необходимые нам функции, официальная - нет.

Проще гребенку снять ))))
проще новый дисплей купить )))
