I think I need some help

Hi there,

at first a really big commendation for your work.
Since a few hours I am trying to understand the cdc_arduino_ported_k9spud_vwcdpic programm.
I use the arduino nano right now. By simple copy and paste the program into the Arduino IDE and check it the compiler says:

Error at compyling.`

Those are the most important things I think. Because i'm relativ new to Ardunio I'm out whats wrong there. In C# I would think that the variable is not definied, but that should already happend, or? And the second part should be a consequential error.

What do you think?

Thank you very much and greetings,

put functions.ino into same folder as cdc_arduino_ported_k9spud_vwcdpic.ino

[DaMusikant]

Wow, that was easy.
Your great, thank you :)

[tomaskovacik]

no problem :)
