Hey @ricardocrudo
Thank you again for your reply.
Alright, I already found the defines in the config.h, but wasn’t sure if its a good
idea to change the values in there. With the second encoder available I can do
the most importend things for the first software iteration. 
I also managed to include your changes into due_x variant.cpp, but the due still never connects to
the MOD GUI. I tried it with the tutorial codes, and my code.
Anything else I need to do, or do you maybe have a good idea how i can check if data gets sent to the MOD? Maybe a flag or anything i need to set?
I used the verbose compilation mode to check if i got the right file for the changes. So I’m sure i got the right one.
