Конфигурация: Программатор: Arduino uno , «arduino as ISP». Жертва: Arduino pro mini ATMega 328P 16mHz. Версия программы: 1.8.13 . Порт, программатор и плата, прописаны верно.

Примечания: Программатор и жертва работают. Бутлоадер прописался успешно . Функция на которую матюкается компилятор вроде как тоже правильно написана. В чем дело — не пойму.

Может подскажете что поправить надо?

I am extremely new to Arduino coding and have downloaded a sketch for the PCA9685 to use with model railroading and turnout control. When I verify the sketch I get several errors … I don’t even know how to resolve and could use some assistance. There are two sketches:

1:

    /***************************************************
  This sketch can be used to operate any number of turnouts on a
  Model Railroad. Code blocks can be added to accomodate any number
  of servos. This sketch uses only two servos for this demonstration.

  The pushbutton can be replaced with a SPST switch
  commonly used on a control panel. Three pin Bicolor LED can be used
  in place of two seperate LEDs in each circuit.

  10K Ohm pulldown resistor used on switch
  330 Ohm resistor used on LEDs. One per pair of LEDs
