Hi, when I'm trying to compile the example: DigisparkSoftSerial - TwoPortReceive, I receive a error:

The only way to compile is removing the lines:

  Serial.begin(9600);
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

Try https://github.com/ArminJo/DigistumpArduino.

Well it work anyway without the lines that I remove. But now I have another problem, when I add "DigiKeyboard.h" library in the same program that have:

include

OR

include

I get errors. If I compile this individual libraries isolated (different programs and folders) I can compile.

[ArminJo]

You know what multiple definition of__vector_2'` means?

[djayor]

I don't know, but if I just add these 3 libraries to the program, I get that error. I believe that one of the variables mentioned in this libraries is repeated.

[ArminJo]

In short vector2 is for Pin Change Interrupt Request 0. So multiple libraries try to use the same hardware resource the vector2. This is a common problem with libraries using limited hardware resources and cannot be solved.

[djayor]

Oh thanks, this makes sense. I solve the problem using this library, instead of "SoftSerial.h": https://github.com/J-Rios/Digispark_SoftSerial-INT0 And instead of "DigiKeyboard.h" I used: https://github.com/adafruit/Adafruit-Trinket-USB/tree/master/TrinketHidCombo

Works fine this way.
