Hi all,
Newbie here, I still do not have the digi as I want to find out a few things before I buy it-
First of all, as I understand, the digi connects to the P1 and P5 but does not use all the gpios. Can someone tell me which gpios are left for me to use?
I am planning to use this as a Car Headunit, so need a few gpios (for infra red remote, power shut down, remote 12v relay etc).
Another question I have - I want to use this to get a DTS signal - it is not clear from the FAQ wheather this is feasable or not? could I run it with raspbmc? is this OS supported or not? and what ramifications are there if it is not supported but still working?
And last question - when outputting surround sound via hdmi, it is not possible to use the analog out for the video signal.
If I use the digi instead- outputting DTS over SPDIF- will there be a video signal over the analog video out?
Thanks for all who got this far :)

HiFiBerry team Only the I2C pins are used. However, you should not use the 3.3V provided by the Raspberry PI, as this is limited to only a few mA.
DTS output is feasible. OpenElec should work with DTS. However as we do not develop these software, we can't guarantee, that it will work.
The HiFiBerry Digi does not interact in any way with the HDMI output. We have heard, that outputiing sound over the Digi and video over HDMI works with some XBMC distributions. But again, we can't guarantee the 3rd-party software works in a specific use case. Therefore we recommend asking software-specific question to the programmers of the software.

Erez Siag Hi Daniel,
Thanks for your reply!
Regarding my last question - I actually meant the opposite-
Will the video be output through the analog out? -
Erez Siag And another question-
You say that only the I2C pins are used, but from what I understand these are only found in the P5 header-
Then why is the P1 used at all? or is it entirely free for me to use? -
HiFiBerry team No, the I2C (C not S!) pins are on the P1 header. P5 is for the I2S data.
Best regards

Erez Siag OK, thanks!
So I have one last question -
Since the digi comes abutted to the Pi, how can I connect to the free gpio?
Also, where can I get the exact pinout of the specific GPIOs that are not used?
I really dont want to make any mistakes with this, as this could probably harm the digi?
