Написал програмку для микроконтроллера PIC16F84A которая декодирует PPM сигнал. Хочу проверить её работоспособность. Для этого думал подключить декодер к разъёму “Тренер” на передатчике. Замерил напряжение на контакте “сигнал” а там 9 вольт! 😃
Вопрос: как можно подключить декодер PPM к передатчику, принимая во внимание что на входе микроконтроллера высокий уровень должен быть ~5 вольт, а низкий ~0
Вот так:
Вот так:
Спасибо!
Работает и просто от делителя напряжения.
