Задача - тахометр для бензиныча 500-20000 об/мин (частота импульсов 8-330 гц) дискретность 10 об/мин. Мозг - AVR.
Вопрос как измерять - тупо частоту, вроде очень тупо. Через период повторения импульсов?
Нету у меня ни винта самолета ни лопастей вертолета. Есть мотор.
Задачку решил. Правда диапазон другой получился 900- более 100000 об мин. меня устроит - бензинки так быстро не крутятся…
