Контроллер клавиатуры PS/2 для Пентагона
https://www.youtube.com/watch?v=Fo7E3_Vwk2w&t=1031s
Кто-то смотрел или повторял это? Собрал для пентагона - не работает. Память только поставил AS6C1008, так как меньше нет ничего. Все неиспользуемые ноги шины адреса заземлил. CE# - на землю, СЕ2 - подтянул к питанию. По итогу вместо прижима KD0 - KD4 к земле - там пачка импульсов. Пачка импульсов также на WE памяти. Вручную (замыкая адрес и данные) все работает. Ниже скетч для ардуины
