My name is Eero and im from Finland. I studying in electric automation engineer specialized to programming. I am at first year and it taks 3-4 years to graduate.
I have done some retrofits to my previous Audi A4 2009, but now i am learned programmin mostly Python and C# i realized what nice things i can do to my car.
I have changed new steering wheel from Audi TTS mk2 to my Audi A7 2011. Airbag problem was solved easily with R8 airbag with two detonators but problem is buttons. TTS steering wheel have two buttons more than in A7.
I do not know is that TTS with newer LIN BUS system than A7, or is those buttons giving just different signals and A7 does not understand them. Any of those buttons working, just lights are working but they coming from + and ground.
Anyways, i want to read the LIN BUS signals of the buttons. Can i do it with Macchina m2?
I have to read what TTS SW buttons giving and what A7 SW is giving. So i can translate TTS signal to A7.
How can i do that, is not clear yet. I have to program some microprocessor module to translate one code to another, LIN wire which is coming from steering wheel have to go trough that module.
Is there anyone who having experience with this?
