  • Здравствуйте. Не могу понять смысл конденсатора C1 между коллектором VT1 (+5v) и шиной RDY. Да и на схеме его нет. Пока его не убрал с платы доктор не видел контроллеров. Видимо он должен идти не на RDY, а на GND.

    Спасибо. Посмотрел. В ролике говорится про 22 pF, а Вашей спецификации он указан как 100nF. В ближайшее время потыкаю осцилом по ногам сокетов. Действительно ли там постоянно присутствует 12в. Попробую поставить 22 pF и посмотрю будет-ли доктор лечить.

    Этот конденсатор не нужен

    Why is it that after i uploaded v 2.11 all chips are not detected FAIL bad led on

    Ahmed Ibrahim Ahmed 2022-01-08 05:03:35Reply

    Hi, does it work for V2.11 with C1 (100nF) or (22pF) or I remove C1 ?

    Michael Demidov 2022-01-27 19:43:40Reply

    Я не ставил этот конденсатор.

  • +5В и +12В постоянно приходят на восстанавливаемый контроллер. Транзисторы исправны. На RDY высокий уровень всё время.

  • Jason Markham, According to log text, your ‘doctor’ in the parallel high voltage mode (hvpp). For attiny85 you should chose the serial high voltage mode (hvsp). Please change the “hvpp/hvsp” work mode by the specific button (jumper) on the pcb.
