Steering Wheel Control
#1
Hi guys,

I have TB and really enjoying it. And I am new here on this forum as well as for the development boards. I have currently miniatx motherboard in my car (yes I built it once Caputers were famous) and now I would like to change it to TB. However, as I dont understand how to use it with the details below;

This is the original radio's pinout and descriptions
[Image: tl_pinout_anim.gif]

C3
13 Tx (from HU to CDC or PC)
14 Rx (from PC or CDC to HU)
15 GND
16 12V (constant)
17 HU ON (12V when HU is ON)
18 SPDIF IN (***)
19 SPDIF GND (***)
20 (SPDIF GND) (***)


C1
1 DTA
2 CLK
3 MIRQ
4 n/c
5 Radio ON
6 GND



C3 is associated with steering wheel control. And C1 is goes to the head display. I checked Renault forums and other forums as well and found here and this is very old post that I can not be sure with their circuit. And they are referring C3's Pin 13, 14,15. 

Anyone can help me how to get it work properly with TB? How to get button's that I can use as hotkey on VLC? If you can explain me for Debian and Android, I would be also happy if someone provide me the information about C1 port how to send data to lcd Smile .

Thanks a lot
