Почему срабатывает только последний LED?

[demonpit]

Собрал в PROTON IDE и PROTEUS две схемы на pic18F4550: USB вольтметр для двух ног (2 и 3) и USB LED на две ноги (33 и 34). Отдельно обе схемы работают отлично. Меня интересует USB LED. Отдельно эта схема работает и включает LEDы по команде с ПК кнопками СТАРТ1 и СТАРТ2. Также и выключает LEDы СТОП1 и СТОП2. Попробывал объединить две схемы в одну - срабатывать стала только LED на кнопке СТАРТ2. Если сделать еще пару кнопок и добавить в схему пару LED (т.е. LED1 (33), LED2 (34), LED3 (35) и Led4 (36)), с добавлением команд в PROTON и DELPHI для этих кнопок, при нажатии на программные кнопки СТАРТ 1,2,3 и 4 срабатывает только последняя 4 кнопка - первые три полный мертвяк. Подскажите пожалуйста, как сделать, чтобы при нажатии кнопок СТАРТ 1,2,3 и 4 срабатывали, соответственно, LED 1,2,3 и 4. Вот исходник для PROTON IDE для двух кнопок и двух вольтметров:

Ладно. Спасибо за помощь. Сам все сделал. Тема закрыта.
