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.

Pretty much the same thing as many of the new china Tablets .
The firmware uses cramfs , but I've found another firmware that works,,,, BUT since it's made to be used with a touchscreen no USB or remote is working.
Is there anyone who has an idea on what to to..
The firmware i used to flash the box with is rooted and that's really all I need.

Haha
Very cute . But I'm not sure if it was so helpfull...

Meh - just reread the question. If you can't install anything on it then I don't see what you can do. Reflash back to stock and leave it in a working state.

Well
I don't agree... I currently have the stock FW installed but I wan't to root the device to make 100% use of the hardware

Bluetooth audio codec setting won't stick

Hi all,
I have a Mi 9 lite and a pair of bluetooth headphones. Both are supposed to support a range of bluetooth audio codecs (1) , but I can't get them to use anything but SBC. Trying to find a solution has been frustrating: across the web there's many people who encounter the problem and some find solutions as well, but none work for me / the Mi 9 lite.
In developer options I can see the alternative codecs (2). I can't change any of them until I connect the bluetooth headphones. When connected I can choose any codec (3) , but after setting the value and leaving the settings page , it switches back to SBC.
- I've tried every suggestion I could find: set with BT on, off, either connected to headphones or not connected , battery saver switched on / off, you name it.
- Some people report that when they switched off dual audio the problem was solved (4). But I can't even find these advanced bluetooth settings, they seem to be a samsung galaxy feature.
- Others simply don't have the problem, they can switch freely as long as their headphones support the codec.
- Some people don't have as many codecs, etc etc.
I've pretty much tried all the suggestions and then some, and I'm out of ideas except for chalking a pentagram on the floor and dancing around it with the phone in the middle .
If you have a suggestions or ideas where to look next I would appreciate hearing from you. If I should provide some additional information I'd be happy to do so.
PS I'm no developer but I've been on the android SDK website and found some posts suggesting that the thing to accomplish would be to edit some config file that has the bluetooth codec priority list. No idea if that is of any use though.
EDIT: Having a great time bouncing around in the SDK and finding out what ADB does. Little idea what I'm doing but I'm getting a little taste of why people like messing around with their devices so much. Would rooting the device allow me to explore the filesystem and see what's in /etc/ and so on? Or is that just the fast lane to Brickville?
Dark background screens are mine, light one shows advanced options others seem to have. Numbers correspond with those above

Cheers.

any luck with this issue? any discoveries during further investigation? I've run into this problem frequently on many xiaomi devices (and others). from what I understand, just because they show up in that list, doesn't mean they apply to the given paired device capabilities, which ultimately dictate which option will be used. basically, it doesn't mean anything, until the devices are paired, then it is trial and error to see which setting "sticks". very frustrating to say the least.

Kindle Fire HD 3rd Generation (Soho) - UART

Hi all,
Following on from my previous post (https://forum.xda-developers.com/ki...p/kindle-fire-hd-3rd-generation-soho-t4038369), I have successfully built an image, however (unsurprisingly) it doesn't work. Specifically, after flashing it using TWRP and restarting, my soho goes into a bootloop. Does anyone know how to access UART on soho so I can debug? I can't seem to find any info on it. Or any other suggestions to find out what is the problem?
Thanks,
Jack K

Hmm, seeing I couldn't find info online, I decided to open it up, I found what I think are the pins. It says DEBUG next to the area immediately below the blue square and left of the yellow circle on this graphic from the iFixit soho teardown (the word DEBUG is obscured by the colours):

Argh, linking not allowed yet. Not been around here long enough.
https :// d3nevzfk7ii3be . cloudfront . net / igi / IRYImVnOnk4cREVy . huge
Oops, works now for some reason.

Someone asked on another thread how this is going.
In short, I'm really out of my depth when it comes to hardware debugging, so I've basically not done anything. Is anyone willing to help me? I can post a link to my non-booting build for anyone who (at their own risk) wants to flash it to their soho and analyse what might be going wrong with their own serial cable.
Thanks!
