Если кто-нибудь может помочь мне с этой проблемой, я был бы очень признателен.
Вот что я знаю.
У меня есть специальная печатная плата, основанная на процессоре atmega328p.
Я использую atmelstudio 7.0.1645 IDE.
Я использовал мастер ASF для настройки своего проекта.
Я программирую с использованием USBTinyISP.
В моем основном цикле я переключаю светодиод и задерживаюсь на 1 секунду.
Тем не менее, когда я проверяю область, светодиод мигает с частотой 1,6 с
Я проверил предохранители, и все они установлены правильно по умолчанию (E = 0xff, H = 0xD9, L = 0x62) этодолжен дать тактовую частоту 1 МГц.(Внутренний RC 8 МГц плюс деление на 8 прескалеров)
Я использую Службу управления системными часами ASF и Службу задержек.
вызов sysclk_get_main_hz(); возвращает 16000000.
вызов sysclk_get_source_clock_hz(); возвращает 1000000.
вызов sysclk_get_cpu_hz(); возвращает 1000000.
Что мне кажется правильным.
Также, если я скомпилирую и запрограммирую аналогичный проект из arduino ide, функции задержки будут активированы, поэтому ячувствую, что могу исключить любые очевидные проблемы с оборудованием.В любом случае, я просто использую внутренний RC.
Я выследил Гудл за подобные проблемы, но просто получаю обычные проблемы с настройкой часов, которые я чувствую, что я исчерпал.
Любая дополнительная помощь будет оченьоценили.Спасибо.
