[aster94]

Hi!

I made a library to make the comunication and the development of software for the ECU easier
Keyword Protocol 2000
I think that the original tutorial has been created by toni_k but i don't know his github name
You may consider to add this to the tutorial
I also made a python script that emulates an ECU and it is very useful for the development, somehow similar to the ECUsim 2000 you pubblish only limited to the iso14230 but free
