In order to control an android headunit I would like to use a multimedia keyboard such as this one :
The First thing I made was to decode CAN signals from the keyboard, using an arduino leonardo and a can shield.
Then, I need help to send things to the headunit. I wanted to use android Keyevent via USB, that can be found here :
But I have no idea how does it works.
I dont know many about android or about arduino, but I'm able to learn quickly, I just need help to understand how does it works.
Does anybody already made similar things?
