|New version of the "button" firmware for the MKV GTI that adds TTL outputs for button presses as well as the serial communication.
|Project finished and web page created. (Raw sniffer and
basic button decode firmware working)
|Download the full package (micro code, bill of
material, logics, and
PCB data) here Can_sniffer.zip.
Current firmware images included:
VW MKV GTI "infotainment bus" 100kbs
- Raw bus dump (sniffer/snoop)
- Basic steering wheel button decode (when you press a button the adapter sends out "BUx" followed by a line return. x = the number of the button pressed. (see documentation with firmware for list of button numbers) Firmware also has TTL outputs for each of the buttons on the steering wheel. These outputs can be directly interfaced to other devices / inputs without using a PC or another micro. For example you can set up the "phone" button to turn on a light when pressed.
Other function / car support should be possible. Email me with questions.
