Line-In or ext.mic. - possible in stereo?

Hello people,
i would like to connect an external mic. to my Blue Angel,
and i allready know about the pin assignment of both connectors (22pin or 2,5mm plug).
My question is:
is the analog to digital converter in the blue angel able to do stereo?
if yes, (where) can i solder a stereo line-in to the curcuit?
btw., i'm very happy i found this (wonderful) forum...
merry X-Mas to all of you!

'Philips UDA1380' chip -> stereo sampling!
on that page:
http://handhelds.org/moin/moin.cgi/BlueAngel
they say that BA uses a 'Philips UDA1380' chip
and they have a link for a datasheet (68 pages, pdf) for that chip:
http://www.nxp.com/acrobat_download/datasheets/UDA1380_4.pdf
'Philips UDA1380' chip is capable of doing stereo sampling,
so a BA could be a stereo recorder!
if anybody knows how this could be done,
please give me a hint ...

some things i found:

... if anybody knows if it would work to solder an line-in to the chip
and use that line in for 44khz/16bit stereo recordings,
please let me know...

Well, I took a look at the hi-res photos of the boards on the wiki here:
http://forum.xda-developers.com/files/naked-blue-insane.jpg
and if you rotate the image around 180 degrees, I think the chip in question will be in the top centre of the image on the right.
From looking at the photo, these pins are already hooked up to something. They might even be connected to the same thing, it's hard to tell from the photo. I've not opened my BA myself as it's under guarantee.

hi fraser,
yes, that one is the chip, and yes, it looks like all pins are soldered to the board, but i'm quite sure that they are not connected to anything,
because there is no 'line-in" anywhere on the board (not even a stereo line signal), and thats the purpose of pin 27&29...
the blue angel mic(s) (internal and external) are quite sure connected to pin 31.
i have 2 problems:
1.
i don't know if it's ok to connect an external line to the chip directly,
or if there have to be some 'signal tweak' before sending it into the chip
2.
i don't know if the 'default' driver is able to 'receive' or use stereo signals
- is there some sort of 'software mixer', like in a regular windows pc?
i really need help from an electronics guru...

$5 for anyone who makes this simple program for me

Hey, I've got a 'ghetto' little in car computer system set up and it's a pain having to tap-tap on a 7 inch onscreen keyboard obviously not made for fingers. A full size keyboard just isn't practical in a car environment, however the Kaiser already has a very nice petite one built in.
If anyone can make me a program to send keystrokes FROM the phone TO the computer via USB or bluetooth (usb preferred) I'll paypal them $5, or whatever they see it worth. Thanks a lot!

Good Luck finding someone to do THAT much in depth programing for $5.
But Hey You could get a Sub Sammich!

It's not that much work... (although I'm not taking on any more projects at the moment).
You just need a RAPI Client/Server App coding that can pass the key strokes back and forth.

I'm confused if by car computer system you mean a legitimate computer in your car. If so, GRemote should do the trick http://forum.xda-developers.com/showthread.php?t=427097

you could also use mymobile. It mirrors the keystrokes to the computer or vice versa. not sure if this is what you need but thought I would throw it out there.

ill do it
and retire to oz on the payout..... all £3.28 @ todays exchange rate

It could be helpful. I plan to install a computer in my Nissan Xterra, ITX board and 7" touchscreen LCD. I have the ITX board and everything is ready to install but it's too much money to buy the touchscreen LCD. So instead I deside to break a laptop a part (Dell LH400 NON touchscreen 12") I plan to have the screen in the front somewhere and the board will be in the back and control the laptop with my tilt (w/USB cable or BT). It will be nice to have this kind of software on my tilt.
mayby it should have shortcut to to find application on the computer, like video, pix, gps software, players and more

Gremote
as haywiremonkey said Gremote works very well for that i use it all most every day, i use it over wifi but it says it works over bt also just never tried it. i found gremote in the touch pro software section of the forum.

Thanks for the link, this application is PERFET

[Q] Nook Color wl1271 unlock?

its a long shot but maybe some here can help or at least refer me to someone who can...
i was wondering if anybody was able to enable the Bluetooth and/or FM capabilities of the Nook Color. as it has the wl1271 which according to TI supprorts BlueTooth and FM Transmitting and receiving . it seems to me that it might be a simple software change to enable both of them.
i tried building the original kernel and inserting the BT firmware scripts i download from TI (Froyo_L27.5.2_Connectivity_1271_Panda-1.0-Linux-x86-Install)
and i still cant get the blutooth to show up :-/
any ideas? is there a possibility that the UART interface is not connected on the NC to the BT and therefore cannot control it? i assumed that this chip has only one Host interface which the wifi uses and therefore there shouldn't be any problems with the other capabilities

This isn't the Q&A section

Apply your question(s) in the proper sub-forum, or it might result in a temporary vacation
Actually i'll leave this open, see where it leads to

very interesting read...

wow
it is a great post but it got dirty with all bunch of other topics, i think this issue deserves its own thread as it can lead to enabling 2 amazing features for the nook.
so, basically we need to see if the HCI interface pins are connected right to enable this feature...
the minimum requirements according to the document are:
12 BT_EN <--> GPIO on OMAP.
13 HCI_TX <--> UART lines on the OMAP. UART2_TX
15 HCI_RX <--> UART lines on the OMAP. UART2_RX
17 HCI_CTS <--> OMAP UART CTS line. UART2_CTS
19 HCI_RTS <--> OMAP UART RTS line. UART2_RTS
but how can we check that? is it possible that B&N didnt connect this on purpose ?
that would be such a waste, on the other hand they didnt put a Mic support 3.5 headphones jack even that its supported...

Someone needs to open the NC... trace and measure...
as the USB host will not provide any data...
Edit:
I found this link from ti... pre-compiled linux drivers...
you may need a panda board...

The WL127x doesn't work like that. It goes through the UART, so there's no enumeration. The kernel doesn't know if it's working until you run succeed in running an hciattach on the interface.

Sony Xperia Z3 Compact screen static/white noise.

I have recently gotten a Z3 Compact. It had no screen and i have now fitted a new screen. Everything works. It turns on. The screen turns on. It just only displays the full screen in a small section at the top and like 90% of the screen is a static/white noise display. It seems like it isnt displaying at its full resolution.

Does anyone have any idea what to do.
Things i have tried are:
Doing an update through pc companion
Updating via pc companion.
Re-connecting the screen.
The screen does however work. The full screen works as a touch screen and i have to tap on the center of the screen to select shutdown options even though the display is only on the top strip like in the picture above.
any help would be much appreciated,
thanks,
wivane

Either you have faulty new display or incompatible (Sony used few display manufactures for various models-reflashing kernel should work), or you damaged port (pins) while replacing...
My guess...

yeah, my thoughts too. as i can remember, in the system files u can check what display is installed. (software) maybe it isn't a "original" matching display.

Stock kernel should check LCD version when flashed and rewrite proper drivers... if that is the case...

Concept: Android system with multiple inputs and outputs

I'm well behind the curve on Android in the car and I'm not sure this is even the right place for it but I have a concept for a system and I'm not sure whether the current state of the art permits it. But here goes anyway.
The car is exotic and rare: a Renault Avantime. Here's the cockpit:

You'll note that it's a work of art (may not be to your taste but it's one of those rare beasts; a concept show car that actually went into production). So I don't want to mess with it too much. You'll also note that there's a bump with a Satnav screen (factory system: old VDO/Dayton thing) on top of the dash. There's also a large flap cover forward of the gearshift; that covers a double-DIN hole which was used for the factory CD and satnav controls panel. The factory radio is a headless unit under the seat which runs a dashboard display and steering wheel controls - with a remote for more complex functions.
What I want to install is an Android system with multiple inputs and outputs. The primary display would take the place of the flap forward of the gearshift. The brains of the thing may or may not be integrated into that display.
Inputs would consist of:
- a cabin webcam used for Skype etc.
- a backup camera (no factory fit)
- a forward-looking thermal camera for night vision
The primary touchscreen display would be in front of the gearshift as described. The existing Satnav display would be adapted for a secondary screen (probably not a touchscreen; just a display): normally it would show Google Maps - or some other app for nav data. But it would be selectable via software to display the backup camera view, the thermal camera view, or the Skype display when in a Skype video call.
Obviously the unit would need to be capable of controlling and driving an external AM/FM receiver/amp for that side of the entertainment functionality.
Is any Android system capable of handling these multiple inputs and outputs? The ability to display specific apps on the secondary display is kinda crucial to what I want to do here; are there any general solutions to getting multiple video streams into and out of an Android device? Or would I be better considering a bespoke car PC based on Linux or something? Any suggestions gratefully received.
